"tooltip-text"	Read-Write	Sets the text of tooltip to be the given string. Also see `gtk.Tooltip.set_text().` This is a convenience property which will take care of getting the tooltip shown if the given string is not `None`: GtkWidget:has-tooltip will automatically be set to `None` and there will be taken care of GtkWidget::query-tooltip in the default signal handler. Default value: `None`. This property is available in GTK+ 2.12 and above.
"visible"	Read-Write	If `True`, the widget is visible

Description

The gtk.Widget class is the base class for all PyGTK widgets. It provides the common set of method and signals for the widgets including:

drag and drop setting and management methods
selection methods
methods to realize, map and show widgets
methods to manage size allocation and requests
methods to initiate widget redrawing
methods to deal with the widget's place in the widget hierarchy
event management methods
methods to modify the style settings
methods to access the default resources

gtk.Widget introduces style properties - these are basically object properties that are stored not on the object, but in the style object associated to the widget. Style properties are set in resource files. This mechanism is used for configuring such things as the location of the scrollbar arrows through the theme, giving theme authors more control over the look of applications without the need to write a theme engine in C.

Use the gtk.widget_class_install_style_property() function to install style properties for a widget class, the gtk.widget_class_find_style_property() function or the gtk.widget_class_list_style_properties() function to get information about existing style properties and the style_get_property() method to obtain the value of a style property.

Methods

gtk.Widget.set_allocation

    def set_allocation(allocation)

allocation :

a gtk.gdk.Rectangle.

Note

This method is available in PyGTK 2.22 and above.

The set_allocation() method sets the widget's allocation. This should not be used directly, but from within a widget's "size_allocate" implementation.

gtk.Widget.get_allocation

    def get_allocation()

Returns :

a gtk.gdk.Rectangle

The get_allocation() method returns a gtk.gdk.Rectangle containing the bounds of the widget's allocation.

gtk.Widget.drag_check_threshold

    def drag_check_threshold(start_x, start_y, current_x, current_y)

`start_x` :	the X coordinate of start of drag
`start_y` :	the Y coordinate of start of drag
`current_x` :	the current X coordinate
`current_y` :	the current Y coordinate
Returns :	`True` if the drag threshold has been passed.

The check_drag_threshold() method checks to see if a mouse drag starting at (start_x, start_y) and ending at (current_x, current_y) has passed the+ drag threshhold distance, and thus should trigger the beginning of a drag-and-drop operation.

gtk.Widget.drag_get_data

    def drag_get_data(context, target, time=0L)

`context` :	a `gtk.gdk.DragContext`
`target` :	an atom
`time` :	a timestamp or 0L to specify the current time

The drag_get_data() method gets the data associated with a drag specified by drag_context and target. When the data is received or the retrieval fails, a "drag_data_received" signal will be emitted. Failure of the retrieval is indicated by the length field of the gtk.SelectionData being negative. However, when the drag_get_data() method is called implicitly because gtk.DRAG_DEFAULT_DROP was set, the widget will not receive notification of failed drops.

gtk.Widget.drag_highlight

    def drag_highlight()

The drag_highlight() method draws a highlight around a widget. This will attach handlers to "expose_event" and "draw", so the highlight will continue to be displayed until the drag_unhighlight() method is called.

gtk.Widget.drag_unhighlight

    def drag_unhighlight()

The drag_unhighlight() method removes the highlight that was set by the drag_highlight() method.

gtk.Widget.drag_dest_set

    def drag_dest_set(flags, targets, actions)

`flags` :	the flags that specify what actions should be taken on behalf of a widget for drops onto that widget. The targets and actions fields only are used if `gtk.DEST_DEFAULT_MOTION` or `gtk.DEST_DEFAULT_DROP` are given.
`targets` :	a sequence of target tuples
`actions` :	a bitmask of possible actions for a drop onto this widget.

The drag_dest_set() method sets up a widget as a potential drag drop destination. The value of flags is a combination of the GTK Dest Defaults Constants.

targets is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

The value of actions is one of the GDK Drag Action Constants.

gtk.Widget.drag_dest_set_proxy

    def drag_dest_set_proxy(proxy_window, protocol, use_coordinates)

`proxy_window` :	the `gtk.gdk.Window` to forward drag events to
`protocol` :	the drag protocol that `proxy_window` accepts
`use_coordinates` :	if `True`, send the same coordinates to the destination, because it is an embedded subwindow.

The drag_dest_set_proxy() method sets a proxy gtk.gdk.Window specified by proxy_window that drag events are forwarded to on behalf of the widget. The value of protocol is one of the GDK Drag Protocol Constants.

If use_coordinates is True, the same coordinates are sent to the destination because the widget's an embedded subwindow.

gtk.Widget.drag_dest_unset

    def drag_dest_unset()

The drag_dest_unset() method clears the information about a drop destination set with the drag_dest_set() method. The widget will no longer receive notification of drags.

gtk.Widget.drag_dest_find_target

    def drag_dest_find_target(context, target_list)

`context` :	the drag context
`target_list` :	a list of droppable targets, or `None`.
Returns :	the first target that the source offers and the dest can accept, or `None`

The dest_find_target() method looks for a match between the targets in the gtk.gdk.DragContext specified by context and the target_list, returning the first matching target, or NONE if no match is found. The list specified by target_list should usually be the return value from the drag_dest_get_target_list() method, but some widgets may have different valid targets for different parts of the widget; in that case, they will have to implement a "drag-motion" handler that passes the correct target list to this method. target_list is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

gtk.Widget.drag_dest_get_target_list

    def drag_dest_get_target_list()

Returns :

the list of targets or None if no targets are set

The drag_dest_get_target_list() method returns the list of targets this widget can accept from drag-and-drop. The returned value is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

gtk.Widget.drag_dest_set_target_list

    def drag_dest_set_target_list(target_list)

target_list :

a list of droppable targets, or None

The drag_dest_set_target_list() method sets the target types (that this widget can accept from drag-and-drop) to the list specified by target_list. The widget must first be made into a drag destination with the drag_dest_set() method. target_list is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

gtk.Widget.drag_dest_add_image_targets

    def drag_dest_add_image_targets()

Note

gtk.Widget.drag_source_set

    def drag_source_set(start_button_mask, targets, actions)

`start_button_mask` :	the bitmask of buttons that can start the drag
`targets` :	a list of targets that the drag will support
`actions` :	the possible actions for a drag from this widget.

The drag_source_set() method sets up the widget to start a drag operation when the user clicks and drags on the widget. The widget must have a window. The value of start_button_mask is a combination of the GDK Modifier Constants.

The value of actions is one of the GDK Drag Action Constants:

gtk.Widget.drag_source_unset

    def drag_source_unset()

The drag_source_unset() method unsets the drag source for the widget that was set up by the drag_source_set() method.

    def drag_source_set_icon(colormap, pixmap, mask=None)

`colormap` :	the colormap of the icon
`pixmap` :	the image data for the icon
`mask` :	the transparency mask for an image.

The drag_source_set_icon() method sets the icon that will be used for drags from the widget using the specified pixmap and mask. colormap specifies the colormap to be used to create the icon. The drag_source_set_icon_pixbuf() method should be used instead of this method.

gtk.Widget.drag_source_set_icon_pixbuf

    def drag_source_set_icon_pixbuf(pixbuf)

pixbuf :

the gtk.gdk.Pixbuf for the drag icon

    def drag_source_get_target_list()

Returns :

the list of targets or None if no targets are set

Note

This method is available in PyGTK 2.6 and above.

The drag_source_get_target_list() method returns the list of targets this widget can provide for drag-and-drop. The returned value is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

gtk.Widget.drag_source_set_target_list

    def drag_source_set_target_list(target_list)

target_list :

a list of droppable targets, or None

Note

This method is available in PyGTK 2.6 and above.

The drag_source_set_target_list() method sets the target types (that this widget can provide for drag-and-drop) to the list specified by target_list. The widget must first be made into a drag source with the drag_source_set() method. target_list is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

gtk.Widget.drag_source_add_text_targets

    def drag_source_add_text_targets()

Note

This method is available in PyGTK 2.6 and above.

The drag_source_add_text_targets() method adds the text targets supported by gtk.SelectionData to the target list of the widget's drag source using an info value of 0. If you need another value for info, use the gtk.target_list_add_text_targets() function and the drag_source_set_target_list() method.

gtk.Widget.drag_source_add_image_targets

    def drag_source_add_image_targets()

Note

This method is available in PyGTK 2.10 and above.

The drag_source_add_image_targets() method adds the image targets supported by gtk.SelectionData to the target list of the widget's drag source using an info value of 0. If you need another value for info, use the gtk.target_list_add_image_targets() function and the drag_source_set_target_list() method.

gtk.Widget.drag_source_add_uri_targets

    def drag_source_add_uri_targets()

Note

This method is available in PyGTK 2.10 and above.

The drag_source_add_uri_targets() method adds the URI targets supported by gtk.SelectionData to the target list of the widget's drag source using an info value of 0. If you need another value for info, use the gtk.target_list_add_image_targets() function and the drag_source_set_target_list() method.

gtk.Widget.drag_begin

    def drag_begin(targets, actions, button, event)

`targets` :	the list of targets supported by the widget drag
`actions` :	the allowed drag operations for the drag
`button` :	the button the user pressed to start the drag
`event` :	the `gtk.gdk.Event` that triggered the drag
Returns :	a new `gtk.gdk.DragContext`

The drag_begin() method starts a drag on the source side. The method only needs to be used when the application is starting drags itself, and is not needed when the drag_source_set() method is used. targets is a sequence (list or tuple) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

The value of actions is one of the GDK Drag Action Constants.

button is the button that the user pressed to start the drag operation. event is the gtk.gdk.Event that triggered the start of the drag operation (the button press). This method returns the gtk.gdk.DragContext for the drag operation.

gtk.Widget.grab_add

    def grab_add()

The grab_add() method makes the widget the current grabbed widget. This means that interaction with other widgets in the same application is blocked and mouse as well as keyboard events are delivered to this widget.

gtk.Widget.grab_remove

    def grab_remove()

The grab_remove() method removes the grab from the widget. You have to pair calls to the grab_add() and grab_remove() methods.

gtk.Widget.rc_get_style

    def rc_get_style()

Returns :

the resulting style.

The rc_get_style() method finds all matching RC styles for the widget, composites them together, and then creates a gtk.Style representing the composite appearance.

gtk.Widget.selection_owner_set

    def selection_owner_set(selection, time=0L)

`selection` :	an atom representing the selection to claim
`time` :	a timestamp or 0L to use the current time
Returns :	`True` if successful

The selection_owner_set() method claims the ownership of the selection specified by selection for the widget.

gtk.Widget.selection_add_target

    def selection_add_target(selection, target, info)

`selection` :	an atom representing the selection
`target` :	an atom representing the target for the selection
`info` :	an integer ID that will be passed to the application

The selection_add_target() method adds the specified target to the list of supported targets for the specified selection. info is an integer ID that will be passed to the application when the "selection-get" handler is called.

gtk.Widget.selection_add_targets

    def selection_add_targets(selection, targets)

`selection` :	an atom representing the selection
`targets` :	a sequence of 3-tuples containing target data

The selection_add_targets() method adds the list of targets (specified by targets) to the list of supported targets for the specified selection. targets is a sequence (Python tuple or list) of 3-tuples that contain information about the targets. The target data contains a string representing the drag type, target flags (a combination of gtk.TARGET_SAME_APP and gtk.TARGET_SAME_WIDGET or neither) and an application assigned integer ID used for identification purposes.

gtk.Widget.selection_clear_targets

    def selection_clear_targets(selection)

selection :

an atom representing a selection

The selection_clear_targets() method remove all targets registered for the specified selection for the widget.

gtk.Widget.selection_convert

    def selection_convert(selection, target, time=0L)

`selection` :	an atom specifying the selection
`target` :	an atom specifying the target type
`time` :	a timestamp for the request or 0L to use the current time
Returns :	`True` if the request succeeded

The selection_convert() method requests the contents of the specified selection for the specified target type. When received, a "selection_received" signal will be generated.

gtk.Widget.selection_remove_all

    def selection_remove_all()

The selection_remove_all() method removes all handlers and unsets ownership of all selections for a widget. This method is called when widget is being destroyed and not usually by applications.

gtk.Widget.destroy

    def destroy()

The destroy() method destroys the widget. When a widget is destroyed, it will break any references it holds to other objects. If the widget is inside a container, the widget will be removed from the container. If the widget is a toplevel (derived from gtk.Window), it will be removed from the list of toplevels, and the reference PyGTK holds to it will be removed. Removing a widget from its container or the list of toplevels results in the widget being finalized. In most cases, only toplevel widgets (windows) require explicit destruction, because when you destroy a toplevel its children will be destroyed as well.

gtk.Widget.unparent

    def unparent()

The unparent() method is only for use in widget implementations. It should be called by implementations of the remove method on a gtk.Container, to dissociate a child widget from the container.

gtk.Widget.show

    def show()

The show() method causes a widget to be displayed as soon as practical. Any widget that isn't shown will not appear on the screen. If you want to show all the widgets in a container, it's easier to call the show_all() on the container, instead of individually showing the widgets. Of course you have to show the containers containing a widget, as well as the widget itself, before it will appear onscreen. When a toplevel container is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel container is realized and mapped.

gtk.Widget.show_now

    def show_now()

The show_now() method is the same as the show() method except if the widget is an unmapped toplevel widget (i.e. a gtk.Window that has not yet been shown), it enters the main loop and waits for the window to actually be mapped.

Note

Because the main loop is running, anything can happen during this method.

gtk.Widget.hide

    def hide()

The hide() method reverses the effects of the show() method, causing the widget to be hidden (removed from the display) by unmapping it.

gtk.Widget.show_all

    def show_all()

The show_all() method recursively shows the widget, and any child widgets (if the widget is a container).

gtk.Widget.hide_all

    def hide_all()

The hide_all() method recursively hides the widget and its child widgets (if any).

gtk.Widget.set_no_show_all

    def set_no_show_all(no_show_all)

no_show_all :

the new value for the "no_show_all" property

Note

This method is available in PyGTK 2.4 and above.

The set_no_show_all() method sets the "no_show_all" property to the value of no_show_all. If no_show_all is True calls to the show_all() and hide_all() methods will not affect this widget.

This method is mostly for use in constructing widget hierarchies with externally controlled visibility, see the gtk.UIManager reference for mote information.

gtk.Widget.get_no_show_all

    def get_no_show_all()

Returns :

the current value of the "no_show_all" property.

Note

This method is available in PyGTK 2.4 and above.

The get_no_show_all() method returns the current value of the "no_show_all" property. If "no-show-all" is True calls to the show_all() and hide_all() methods will not affect the widget.

gtk.Widget.map

    def map()

The map() method maps the widget (causes it to be displayed). This method will also cause the widget to be realized if it is not currently realized. This method is usually not used by applications.

gtk.Widget.unmap

    def unmap()

The unmap() method unmaps the widget (causes it to be removed from the display). This method is not usually used by applications.

gtk.Widget.realize

    def realize()

The realize() method creates the resources associated with a widget. For example, the widget gtk.gdk.Window will be created when the widget is realized. Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically. Realizing a widget requires all the widget's parent widgets to be realized; calling the realize() method realizes the widget's parents in addition to the widget itself. A widget must be inside a toplevel window when you realize it. This method is primarily used in widget implementations, and not in applications. Many times when you think you might need it, a better approach is to connect to a signal that will be called after the widget is realized automatically, such as "expose_event". Or simply using the gobject.connect_after() method to add a handler to the "realize" signal.

gtk.Widget.unrealize

    def unrealize()

The unrealize() method frees all resources associated with the widget, such as the gtk.gdk.Window.

gtk.Widget.queue_draw

    def queue_draw()

The queue_draw() method is equivalent to calling the queue_draw_area() method for the entire area of a widget.

gtk.Widget.queue_draw_area

    def queue_draw_area(x, y, width, height)

`x` :	the x coordinate of upper-left corner of rectangle to redraw
`y` :	the y coordinate of upper-left corner of rectangle to redraw
`width` :	the width of rectangle to redraw
`height` :	the height of rectangle to redraw

The queue_draw_area() method invalidates the rectangular area of the widget specified by x, y, width and height by calling the gtk.gdk.Window.invalidate_rect() method on the widget's window and all its child windows. Once the main loop becomes idle (after the current batch of events has been processed, roughly), the window will receive expose events for the union of all regions that have been invalidated.

Normally you would only use this method in widget implementations. But you might also use it, or the gtk.gdk.Window.invalidate_rect() method directly, to schedule a redraw of a gtk.DrawingArea or some portion thereof. Frequently you can just call the gtk.gdk.Window.invalidate_rect() method instead of this method. This method will invalidate only a single window, instead of the widget and all its children. The advantage of adding to the invalidated region compared to simply drawing immediately is efficiency; using an invalid region ensures that you only have to redraw one time.

gtk.Widget.queue_resize

    def queue_resize()

The queue_resize() method schedules the widget to have its size renegotiated. This method should be called when a widget for some reason has a new size request. For example, when you change the text in a gtk.Label, a resize is queued to ensure there's enough space for the new text.

gtk.Widget.queue_resize_no_redraw

    def queue_resize_no_redraw()

Note

This method is available in PyGTK 2.4 and above.

The queue_resize_no_redraw() method works like the queue_resize() method, except that the widget is not invalidated.

gtk.Widget.size_request

    def size_request()

Returns :

a tuple containing the widget's required width and height.

The size_request() method returns the preferred size of a widget as a tuple containing its required width and height. This method is typically used when implementing a gtk.Container subclass to arrange the container's child widgets and decide what size allocations to give them with the size_allocate() method. Obtaining a size request requires that the widget be associated with a screen, because font information may be needed.

Also remember that the size request is not necessarily the size a widget will actually be allocated.

See the get_child_requisition() method.

gtk.Widget.size_allocate

    def size_allocate(allocation)

allocation :

the position and size to be allocated to the widget

The size_allocate() method sets a size allocation for the widget using the gtk.gdk.Rectangle specified by allocation. This method is only used by gtk.Container subclasses, to assign a size and position to their child widgets.

gtk.Widget.get_child_requisition

    def get_child_requisition()

Returns :

a tuple containing the required size of the widget

The get_child_requisition() method returns a tuple containing the widget requisition width and height. This method is only for use in widget container implementations since it obtains the widget requisition directly. By comparison the size_request() method actually computes the size request and fills in the widget requisition before returning. Because this method does not recalculate the size request, it can only be used when you know that the widget requisition is up-to-date, i.e. the size_request() method has been called since the last time a resize was queued. In general, only container implementations have this information; applications should use the size_request() method instead.

gtk.Widget.add_accelerator

    def add_accelerator(accel_signal, accel_group, accel_key, accel_mods, accel_flags)

`accel_signal` :	the widget signal to emit on accelerator activation
`accel_group` :	the accel group for this widget, added to its toplevel
`accel_key` :	the keyval of the accelerator e.g. `ord('q')`
`accel_mods` :	the modifier key combination of the accelerator
`accel_flags` :	the flag accelerators, e.g. `gtk.ACCEL_VISIBLE`

The add_accelerator() method installs an accelerator for the widget in accel_group that causes accel_signal to be emitted if the accelerator is activated. The accelerator key and modifiers are specified by accel_key and accel_mods respectively. accel_mods should be a combination of the GDK Modifier Constants. accel_flags is a combination of gtk.ACCEL_VISIBLE and gtk.ACCEL_LOCKED (see the GTK Accel Flags Constants). The accel_group needs to be added to the widget's toplevel via the gtk.Window.add_accel_group() method and the signal specified by accel_signal must have signal flags that include the gobject.SIGNAL_ACTION flag (see the GObject Signal Flag Constants for more information). Accelerators added through this method are not user changeable during runtime. If you want to support accelerators that can be changed by the user, the set_accel_path() or gtk.MenuItem.set_accel_path() methods instead.

gtk.Widget.remove_accelerator

    def remove_accelerator(accel_group, accel_key, accel_mods)

`accel_group` :	the accel group for this widget
`accel_key` :	the keyval of the accelerator
`accel_mods` :	the modifier key combination of the accelerator
Returns :	`True` if the accelerator was removed

The remove_accelerator() method removes the accelerator specified by accel_key and accel_mods from the widget's accelerator group (specified by accel_group), previously installed with the add_accelerator() method.

gtk.Widget.set_accel_path

    def set_accel_path(accel_path, accel_group)

`accel_path` :	the path used to look up the the accelerator
`accel_group` :	a `gtk.AccelGroup`.

The set_accel_path() method sets an accelerator (using the key bindings defined in accel_path) in the accelerator group specified by accel_group. This method removes any accelerators for any accelerator group installed by previous calls to the set_accel_path() method. Associating accelerators with paths allows them to be modified by the user and the modifications to be saved for future use. This method is a low level method that would most likely be used by a menu creation system like gtk.ItemFactory. If you use gtk.ItemFactory, setting up accelerator paths will be done automatically. Even when you you aren't using gtk.ItemFactory, if you only want to set up accelerators on menu items the gtk.MenuItem.set_accel_path() method provides a somewhat more convenient interface.

gtk.Widget.can_activate_accel

    def can_activate_accel(signal_id)

`signal_id` :	the ID of an installed signal
Returns :	`True` if the accelerator can be activated.

Note

This method is available in PyGTK 2.4 and above.

The can_activate_accel() method returns True if an accelerator that activates the signal specified by signal_id can currently be activated. This is done by emitting the "can-activate-accel" signal. If the signal isn't overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped.

gtk.Widget.mnemonic_activate

    def mnemonic_activate(group_cycling)

`group_cycling` :	if True grab the focus instead of activating the widget
Returns :	True if the signal was handled

The mnemonic_activate() method emits the "mnemonic-activate" signal on the widget and returns True if the signal was handled. group_cycling is True if the focus is being shifted to the widget and False if the widget should be activated.

gtk.Widget.event

    def event(event)

`event` :	a `gtk.gdk.Event`
Returns :	`True` if the event was handled

The event() method emits the event signals on a widget (those signals should never be emitted without using this method to do so). If you want to synthesize an event though, don't use this method; instead, use the gtk.main_do_event() function so the event will behave as if it were in the event queue. Don't synthesize expose events; instead, use the gtk.gdk.Window.invalidate_rect() method to invalidate a region of the window.

gtk.Widget.send_expose

    def send_expose(event)

`event` :	an expose `gtk.gdk.Event`
Returns :	`True` if the event was handled

The send_expose() method emits an expose event signal on a widget. This method is usually used when propagating an expose event to a child NO_WINDOW widget, and that is normally done using the gtk.Container.propagate_expose() method. If you want to force an area of a window to be redrawn, use the gtk.gdk.Window.invalidate_rect() method. To cause the redraw to be done immediately, follow that call with a call to the gtk.gdk.Window.process_updates() method.

gtk.Widget.activate

    def activate()

Returns :

True if the widget was activatable

The activate() method emits the "activate" signal on the widget that activates it (if it can be activated). Activation is what happens when you press Enter on a widget during key navigation; clicking a button, selecting a menu item, etc. If the widget isn't activatable, the method returns False.

gtk.Widget.set_scroll_adjustments

    def set_scroll_adjustments(hadjustment, vadjustment)

`hadjustment` :	an adjustment for horizontal scrolling, or `None`
`vadjustment` :	an adjustment for vertical scrolling, or `None`
Returns :	`True` if the widget supports scrolling

The set_scroll_adjustments() method sets the horizontal and vertical scroll adjustments specified by hadjustment and vadjustment respectively and returns True. If the widget doesn't support scrolling this method returns False. Widgets that don't support scrolling can be scrolled by placing them in a gtk.Viewport, which does support scrolling. This method emits the "set-scroll-adjustments" signal on the widget.

gtk.Widget.reparent

    def reparent(new_parent)

new_parent :

a gtk.Container to move the widget into

The reparent() method moves a widget from one gtk.Container to another.

gtk.Widget.intersect

    def intersect(area, intersection)

`area` :	a rectangle
Returns :	a rectangle of the intersection of the widget and `area` or `None`

The intersect() method computes the intersection of a the widget's area and area, and returns the intersection in a gtk.gdk.Rectangle. This method returns False if there is no intersection.

gtk.Widget.region_intersect

    def region_intersect(region)

`region` :	a `gtk.gdk.Region`, in the same coordinate system as the widget.allocation. That is, relative to the widget.window for `NO_WINDOW` widgets; relative to the parent window of the widget.window for widgets with their own window.
Returns :	a newly allocated `gtk.gdk.Region` holding the intersection of the widget and `region`. The coordinates of the returned region are relative to widget.window for `NO_WINDOW` widgets, and relative to the parent window of widget.window for widgets with their own window.

Note

This method is available in PyGTK 2.10 and above.

The region_intersect() method computes and returns as a gtk.gdk.Region the intersection of a the widget's area and the gtk.gdk.Region specified by region. Since the result may be empty, use the gtk.gdk.Region.empty() method to check.

gtk.Widget.freeze_child_notify

    def freeze_child_notify()

The freeze_child_notify() method freezes the child notify queue that is used to notify child widgets of child property changes.

gtk.Widget.child_notify

    def child_notify(child_property)

child_property :

a child property

The child_notify() method adds a child property to the widget's child notify queue that is used to notify child widgets of a change to a child property.

gtk.Widget.thaw_child_notify

    def thaw_child_notify()

The thaw_child_notify() method reverses the effect of a previous call to the freeze_child_notify() method.

gtk.Widget.is_focus

    def is_focus()

Returns :

True if the widget is the focus widget.

The is_focus() method returns True if the widget is the focus widget within its toplevel. This does not mean that the gtk.HAS_FOCUS flag is necessarily set; gtk.HAS_FOCUS will only be set if the toplevel widget additionally has the global input focus.

gtk.Widget.grab_focus

    def grab_focus()

The grab_focus() method causes the widget to have the keyboard focus for it's enclosing gtk.Window. The widget must be a focusable widget, such as a gtk.Entry. Also, the widget must have the gtk.CAN_FOCUS flag set.

gtk.Widget.grab_default

    def grab_default()

The grab_default() method causes the widget to become the default widget. The widget must have the gtk.CAN_DEFAULT flag set by calling the gtk.Object.set_flags() method. The default widget is activated when the user presses Enter in a window. Default widgets must be activatable, that is, gtk.Widget.activate() should affect them.

gtk.Widget.set_name

    def set_name(name)

name :

the name for the widget

The set_name() method sets the "name" property of the widget to the string specified by name. Widgets can be named, which allows you to refer to them in a GTK resource file.

gtk.Widget.get_name

    def get_name()

Returns :

the name of the widget

The get_name() method returns the value of the "name" property that contains the name of the widget or None if the widget has no name.

gtk.Widget.set_state

    def set_state(state)

state :

the new state for the widget

The set_state() method sets the state of the widget to the value specified by state. The value of state must be one of the GTK State Type Constants.

Usually you should set the state using wrapper methods such as set_sensitive().

gtk.Widget.set_sensitive

    def set_sensitive(sensitive)

sensitive :

if True make the widget sensitive

The set_sensitive() method sets the "sensitive" property of the widget to the value specified by sensitive. If sensitive is True the widget will be sensitive and the user can interact with it. An insensitive widget appears "grayed out" and the user can't interact with it. Insensitive widgets are known as "inactive", "disabled", or "ghosted" in some other toolkits.

gtk.Widget.set_app_paintable

    def set_app_paintable(app_paintable)

app_paintable :

if True the application will paint directly on the widget

The set_app_paintable() method sets the "app-paintable" property to the value of app_paintable. If app_paintable is True the application will paint directly on the widget.

gtk.Widget.set_double_buffered

    def set_double_buffered(double_buffered)

double_buffered :

if True double-buffer a widget

The set_double_buffered() method sets the widget's flags according to the value of double_buffered. If double_buffered is True the gtk.DOUBLE_BUFFERED flag is set; otherwise it is unset. Widgets are double buffered by default. "Double buffered" simply means that the gtk.gdk.Window.begin_paint_rect() and gtk.gdk.Window.end_paint() methods are called automatically around expose events sent to the widget. The gtk.gdk.Window.begin_paint_rect() method diverts all drawing to a widget's window to an off screen buffer, and the gtk.gdk.Window.end_paint() method draws the buffer to the screen. The result is that users see the window update in one smooth step, and don't see individual graphics primitives being rendered. In very simple terms, double buffered widgets don't flicker, so you would only use this method to turn off double buffering if you had special needs and really knew what you were doing.

gtk.Widget.set_redraw_on_allocate

    def set_redraw_on_allocate(redraw_on_allocate)

redraw_on_allocate :

if True, the entire widget will be redrawn when it is allocated to a new size. Otherwise, only the new portion of the widget will be redrawn.

The set_redraw_on_allocate() method sets a flag that determines if the entire widget is queued for drawing when a widget's size allocation changes. By default, this setting is True and the entire widget is redrawn on every size change. If your widget leaves the upper left are unchanged when made bigger, turning this setting on will improve performance.

Note

For NO_WINDOW widgets setting this flag to False turns off all allocation on resizing: the widget will not redraw even if its position changes; this is to allow containers that don't draw anything to avoid excess invalidations. If you set this flag on a NO_WINDOW widget that does draw on the widget's gtk.gdk.Window, you are responsible for invalidating both the old and new allocation of the widget when the widget is moved and responsible for invalidating regions newly when the widget increases size.

gtk.Widget.set_parent

    def set_parent(parent)

parent :

a parent container

The set_parent() method is useful only when implementing subclasses of gtk.Container. This method sets the container as the parent of the widget, and takes care of some details such as updating the state and style of the child to reflect its new location. The reverse method is the unparent() method.

gtk.Widget.set_parent_window

    def set_parent_window(parent_window)

parent_window :

the new parent window.

The set_parent_window() method sets a non default parent window for the widget.

gtk.Widget.set_child_visible

    def set_child_visible(is_visible)

is_visible :

if True, the widget should be mapped along with its parent.

The set_child_visible() method determines if the widget should be mapped along with its parent. If is_visible is True the widget will be mapped with its parent if it has called the show() method.

The child visibility can be set for widget before it is added to a container to avoid mapping children unnecessarily. The widget's child visibility flag will be reset to its default state of True when the widget is removed from a container. Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself. This method is only useful for container implementations and never should be called by an application.

gtk.Widget.get_child_visible

    def get_child_visible()

Returns :

True if the widget is mapped with the parent.

The get_child_visible() method returns the value set with the set_child_visible() method. This method is only useful for container implementations and never should be called by an application.

gtk.Widget.get_parent

    def get_parent()

Returns :

the parent container of the widget, or None

The get_parent() method returns the parent container of the widget or None if the widget has no parent.

gtk.Widget.get_parent_window

    def get_parent_window()

Returns :

the parent gtk.gdk.Window of the widget

The get_parent_window() method returns the widget's parent gtk.gdk.Window.

gtk.Widget.child_focus

    def child_focus(direction)

`direction` :	the direction of focus movement
Returns :	`True` if focus ended up inside the widget

The child_focus() method is used by custom widget implementations. If you're writing an application, use the grab_focus() method to move the focus to a particular widget, and the gtk.Container.set_focus_chain() method to change the focus tab order.

The child_focus() method is called by containers as the user moves around the window using keyboard shortcuts. The value of direction indicates what kind of motion is taking place: gtk.DIR_TAB_FORWARD, gtk.DIR_TAB_BACKWARD, gtk.DIR_UP, gtk.DIR_DOWN, gtk.DIR_LEFT or gtk.DIR_RIGHT

This method emits the "focus" signal on the widget. Widgets override the default handler for this signal in order to implement appropriate focus behavior. The "focus" default handler for a widget should return:

True if the focus is left on a focusable location inside the widget, and
False if the focus moved outside the widget

If returning True, widgets normally call the grab_focus() method to place the focus accordingly; if returning False, they don't modify the current focus location.

gtk.Widget.set_size_request

    def set_size_request(width, height)

`width` :	the width the widget should request, or -1 to unset
`height` :	the height the widget should request, or -1 to unset

The set_size_request() method sets the minimum size of a widget to the values specified by width and height. You can use this method to force a widget to be either larger or smaller than it normally would be. In most cases, the gtk.Window.set_default_size() is a better choice for toplevel windows than this method. Setting the default size will still allow users to shrink the window but setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, the gtk.Window.set_geometry_hints() can be a useful method as well.

Note

There is an inherent danger when setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hard code a size that will always be correct.

The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it requested. If the size request in a given direction is -1 (unset), then the "natural" size request of the widget will be used instead. Widgets can't actually be allocated a size less than 1 by 1, but you can pass 0,0 to this method to mean "as small as possible".

gtk.Widget.get_size_request

    def get_size_request()

Returns :

a 2-tuple containing the requested width and height

The get_size_request() method returns a 2-tuple containing the width and height of the widget that was explicitly set for the widget using the set_size_request(). A value of -1 for the width or height indicates that that dimension has not been set explicitly and the natural requisition of the widget will be used instead. See the set_size_request() method for more information. To get the size a widget will actually use, call the size_request() instead of this method.

gtk.Widget.set_events

    def set_events(events)

events :

the event mask

The set_events() method sets the event mask for a widget using the value specified by events. The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget's functionality, so be careful. This method must be called while a widget is unrealized. Consider using the add_events() method for widgets that are already realized, or if you want to preserve the existing event mask. This method can't be used with gtk.NO_WINDOW widgets since a widget must have a gtk.gdk.Window to receive events. To get events on gtk.NO_WINDOW widgets, place them inside a gtk.EventBox and receive events on the event box.

The value of events must be a combination of the GDK Event Mask Flag Constants:

gtk.Widget.add_events

    def add_events(events)

events :

an event mask

The add_events() method adds the events specified by events to the event mask for the widget. See the set_events() method for details.

gtk.Widget.set_extension_events

    def set_extension_events(mode)

mode :

the extension events to receive

The set_extension_events() method sets the extension events mask to the value specified by mode. The value of mode must be one of the GDK Extension Mode Constants.

See the gtk.gdk.Window.input_set_extension_events() method for more information.

gtk.Widget.get_extension_events

    def get_extension_events()

Returns :

the extension events for the widget

The get_extension_events() method returns the extension events the widget will receive. See the gtk.gdk.Window.input_set_extension_events() method for more information.

gtk.Widget.get_toplevel

    def get_toplevel()

Returns :

the topmost ancestor of the widget, or the widget itself if there's no ancestor.

The get_toplevel() method returns the topmost widget in the container hierarchy that the widget is a part of. If the widget has no parent widgets, it will be returned as the topmost widget.

Note the difference in behavior as compared to the get_ancestor() method that returns None if the widget isn't inside a toplevel window, and if the window is inside a widget derived from gtk.Window that is in turn inside the toplevel gtk.Window. While the second case may seem unlikely, it actually happens when a gtk.Plug is embedded inside a gtk.Socket within the same application.

To reliably find the toplevel gtk.Window, use the get_toplevel() method and check if the gtk.TOPLEVEL flag is set on the result.

gtk.Widget.get_ancestor

    def get_ancestor(widget_type)

`widget_type` :	a widget type
Returns :	the ancestor widget, or `None` if not found

The get_ancestor() method returns the first ancestor of the widget with the type specified by widget_type. For example:

  widget.get_ancestor(gtk.Box)

returns the first gtk.Box that's an ancestor of the widget. See the get_toplevel() method for information about checking for a toplevel gtk.Window.

gtk.Widget.get_colormap

    def get_colormap()

Returns :

the colormap used by the widget

The get_colormap() method returns the colormap that will be used to render the widget.

gtk.Widget.get_visual

    def get_visual()

Returns :

the visual for the widget

The get_visual() method returns the visual that will be used to render the widget.

gtk.Widget.get_screen

    def get_screen()

Returns :

the gtk.gdk.Screen for the toplevel for this widget.

Note

This method is available in PyGTK 2.2 and above.

The get_screen() method returns the gtk.gdk.Screen from the toplevel window associated with the widget. This method can only be called after the widget has been added to a widget hierarchy with a gtk.Window at the top.

gtk.Widget.has_screen

    def has_screen()

Returns :

True if there is a gtk.gdk.Screen associated with the widget.

Note

This method is available in PyGTK 2.2 and above.

The has_screen() method returns True if a gtk.gdk.Screen is associated with the widget. All toplevel widgets have an associated screen, as do all widgets added into a hierarchy with a toplevel window.

gtk.Widget.get_display

    def get_display()

Returns :

the gtk.gdk.Display for the toplevel for this widget.

Note

This method is available in PyGTK 2.2 and above.

The get_display() method returns the gtk.gdk.Display for the toplevel window associated with the widget. This method can only be called after the widget has been added to a widget hierarchy with a toplevel gtk.Window

gtk.Widget.get_root_window

    def get_root_window()

Returns :

the gtk.gdk.Window root window for the toplevel for this widget.

Note

This method is available in PyGTK 2.2 and above.

The get_root_window() method returns the root window containing the widget. This method should only be called after the widget has been added to a widget hierarchy with a toplevel gtk.Window

The root window is useful for such purposes as creating a popup gtk.gdk.Window associated with the window.

gtk.Widget.get_settings

    def get_settings()

Returns :

the associated gtk.Settings object

The get_settings() method returns the settings object holding the settings (global property settings, RC file information, etc) used for this widget.

gtk.Widget.get_clipboard

    def get_clipboard(selection)

`selection` :	a `gtk.gdk.Atom` or string that identifies the clipboard to use. `gtk.gdk.SELECTION_CLIPBOARD` gives the default clipboard. Another common value is `gtk.gdk.SELECTION_PRIMARY`, which gives the primary X selection.
Returns :	the appropriate `gtk.Clipboard` object. If no clipboard already exists, a new one will be created. Once a clipboard object has been created, it is persistent for all time.

Note

This method is available in PyGTK 2.2 and above.

The get_clipboard() method returns the gtk.Clipboard object for the selection specified by selection. The widget must have a gtk.gdk.Display associated with it, and so must be attached to a toplevel window.

gtk.Widget.get_accessible

    def get_accessible()

Returns :

an atk.Object

The get_accessible() method returns the Accessibility ToolKit (ATK) object for the widget as an atk.Object.

gtk.Widget.set_colormap

    def set_colormap(colormap)

colormap :

a gtk.gdk.Colormap

The set_colormap() method sets the gtk.gdk.Colormap for the widget to the value specified by colormap. Widget must not have been realized.

gtk.Widget.get_events

    def get_events()

Returns :

the event mask for the widget

The get_events() method returns the event mask for the widget that determines the events that the widget will receive. See the set_events() method for more detail about events.

gtk.Widget.get_pointer

    def get_pointer()

Returns :

a tuple containing the X and Y coordinates of the mouse pointer

The get_pointer() method returns a tuple containing the location of the mouse pointer in widget coordinates. Widget coordinates are a bit odd; for historical reasons, they are defined as:

the widget gtk.gdk.Window coordinates for widgets that are not gtk.NO_WINDOW widgets, or
the coordinates relative to the widget allocation for widgets that are gtk.NO_WINDOW widgets.

gtk.Widget.is_ancestor

    def is_ancestor(ancestor)

`ancestor` :	another `gtk.Widget`
Returns :	`True` if `ancestor` contains the widget as a child, grandchild, great grandchild, etc.

The is_ancestor() method returns True if the widget is somewhere inside the hierarchy of the widget specified byancestor

gtk.Widget.translate_coordinates

    def translate_coordinates(dest_widget, src_x, src_y)

`dest_widget` :	a `gtk.Widget`
`src_x` :	the X position relative to the widget
`src_y` :	the Y position relative to the widget
Returns :	a tuple containing the X and Y position relative to `dest_widget`

The translate_coordinates() method returns a tuple containing the translation of the widget x and y coordinates specified by src_x and src_y respectively to coordinates relative to dest_widget. In order to perform this operation, both widgets must be realized, and must share a common toplevel.

gtk.Widget.hide_on_delete

    def hide_on_delete()

Returns :

True

The hide_on_delete() method is a utility method that is intended to be connected to the "delete_event" signal on a gtk.Window. The method calls the hide() method on the widget, then returns True. If connected to "delete_event", the result is that clicking the close button for a window (on the window frame, top right corner usually) will hide but not destroy the window. By default, PyGTK destroys windows when "delete_event" is received.

gtk.Widget.set_style

    def set_style(style)

style :

a gtk.Style, or None to revert to the default style

The set_style() method sets the "style" property to the value of style. The "style" property contains the gtk.Style for the widget. This method interacts badly with themes, because themes work by replacing the gtk.Style.

gtk.Widget.ensure_style

    def ensure_style()

The ensure_style() method makes sure that the widget has a style. This method is useful if applied to an unrealized widget. Usually, if you want the style, the widget is realized, and guaranteed to have a style.

gtk.Widget.get_style

    def get_style()

Returns :

the widget's gtk.Style

The get_style() method returns the value of the "style" property.

gtk.Widget.modify_style

    def modify_style(style)

style :

the gtk.RcStyle holding the style modifications

The modify_style() method modifies the style values on the widget using the values in style. Modifications made using this technique take precedence over style values set via an RC file, however, they will be overridden if a style is explicitly set on the widget using the set_style() method. The gtk.RcStyle object is designed so each attribute can either be set or unset, so it is possible, using this method, to modify some style values and leave the others unchanged.

Note that modifications made with this method are not cumulative with previous calls to the modify_style() method or with such methods as the modify_fg() method. If you wish to retain previous values, you must first call the get_modifier_style() method, make your modifications to the returned style, then call the modify_style() method with that style. On the other hand, if you first call the modify_style() method, subsequent calls to such methods as the modify_fg() method will have a cumulative effect with the initial modifications.

gtk.Widget.get_modifier_style

    def get_modifier_style()

Returns :

the modifier style for the widget. This gtk.RcStyle is owned by the widget.

The get_modifier_style() method returns the current modifier style for the widget as set by the modify_style() method. If no style was previously set, a new gtk.RcStyle object will be created( with all values unset), and set as the modifier style for the widget. If you make changes to this rc style, you must call the modify_style() method, passing in the returned rc style, to make sure that your changes take effect.

Caution

Passing the style back to the modify_style() method will normally end up destroying it, because the modify_style() method copies the passed-in style and sets the copy as the new modifier style, thus dropping any reference to the old modifier style.

gtk.Widget.modify_fg

    def modify_fg(state, color)

`state` :	a widget state.
`color` :	the `gtk.gdk.Color` to assign.

The modify_fg() method sets the foreground color to the gtk.gdk.Color specified by color for the widget in the specified state. All other style values are left untouched. The value of state must be one of the GTK State Type Constants.

gtk.Widget.modify_bg

    def modify_bg(state, color)

`state` :	a widget state.
`color` :	the `gtk.gdk.Color` to assign

The modify_bg() method sets the background color to the gtk.gdk.Color specified by color for the widget in the specified state. All other style values are left untouched. See modify_fg() method for detail on the possible values of state.

Note

modify_bg() only affects widgets that have an associated gtk.gdk.Window. Widgets that do not have an associated window include gtk.Arrow, gtk.Bin, gtk.Box, gtk.Button, gtk.CheckButton, gtk.Fixed, gtk.Image, gtk.Label, gtk.MenuItem, gtk.Notebook, gtk.Paned, gtk.RadioButton, gtk.Range, gtk.ScrolledWindow, gtk.Separator, gtk.Table, gtk.Toolbar, gtk.AspectFrame, gtk.Frame, gtk.VBox, gtk.HBox, gtk.VSeparator, gtk.HSeparator. These widgets can be added to a gtk.EventBox to overcome this limitation.

gtk.Widget.modify_text

    def modify_text(state, color)

`state` :	a widget state.
`color` :	the `gtk.gdk.Color` to assign.

The modify_text() method sets the text color to the gtk.gdk.Color specified by color for the widget in the specified state. All other style values are left untouched. The text color is the foreground color used along with the base color (see the modify_base() method) for widgets such as gtk.Entry and gtk.TextView. See the modify_fg() method for detail on the possible values of state.

gtk.Widget.modify_base

    def modify_base(state, color)

`state` :	a widget state.
`color` :	the `gtk.gdk.Color` to assign

The modify_base() method sets the base color to the gtk.gdk.Color specified by color for the widget in the specified state. All other style values are left untouched. The base color is the background color used along with the text color (see the modify_text() method) for widgets such as gtk.Entry and gtk.TextView. See modify_fg() method for detail on the possible values of state.

gtk.Widget.modify_font

    def modify_font(font_desc)

font_desc :

a font description to use

The modify_font() method sets the font to use to the value specified by font_desc for the widget. All other style values are left untouched.

gtk.Widget.create_pango_context

    def create_pango_context()

Returns :

the new pango.Context

The create_pango_context() method creates a new pango.Context with the appropriate colormap, font description, and base direction for drawing text for this widget. See the get_pango_context() method.

gtk.Widget.get_pango_context

    def get_pango_context()

Returns :

the pango.Context for the widget.

The get_pango_context() method returns the pango.Context with the appropriate colormap, font description and base direction for this widget. Unlike the context returned by the create_pango_context() method, this context is owned by the widget (it can be used as long as widget exists), and will be updated to match any changes to the widget's attributes.

If you create and keep a pango.Layout using this context, you must deal with changes to the context by calling the pango.Layout.context_changed() method on the layout in response to the "style-set" and "direction-set" signals for the widget.

gtk.Widget.create_pango_layout

    def create_pango_layout(text)

`text` :	the text to set on the layout
Returns :	the new `pango.Layout`

The create_pango_layout() method creates a new pango.Layout with the appropriate colormap, font description, and base direction for drawing the specified text for this widget. If you keep a pango.Layout created by this method, you must call pango.Layout.context_changed() in response to the "style-set" and "direction-set" signals for the widget to notify the layout of changes to the base direction or font of this widget.

gtk.Widget.render_icon

    def render_icon(stock_id, size, detail=None)

`stock_id` :	a stock ID
`size` :	a stock size
`detail` :	the render detail to pass to the theme engine or `None`
Returns :	a new pixbuf, or `None` if the stock ID wasn't known

The render_icon() method is a convenience method that uses the theme engine and RC file settings for the widget to look up the stock icon specified by stock_id of the specified size and to render it to a pixbuf that is returned. stock_id should be a stock icon ID such as gtk.STOCK_OPEN or gtk.STOCK_OK. size should be one of the GTK Icon Size Constants:

detail is an optional string that identifies the widget or code doing the rendering, so that theme engines can special-case rendering for that widget or code.

gtk.Widget.set_composite_name

    def set_composite_name(name)

name :

the name to set.

The set_composite_name() method sets a widgets composite name to the value specified by name. The widget must be a composite child of its parent

gtk.Widget.get_composite_name

    def get_composite_name()

Returns :

the composite name of the widget or None

The get_composite_name() method returns the composite name of a widget or None if the widget is not a composite.

gtk.Widget.reset_rc_styles

    def reset_rc_styles()

The reset_rc_styles() method resets the styles of widget and all descendants to the correct values for the currently loaded RC file settings. This method is not useful for applications.

gtk.Widget.style_get_property

    def style_get_property(property_name)

`property_name` :	the name of a style property
Returns :	the property value

Note

This method is available in PyGTK 2.4 and above.

The style_get_property() method returns the value of a style property specified by property_name.

gtk.Widget.set_direction

    def set_direction(dir)

dir :

the new direction

The set_direction() method sets the "direction" property to the value specified by dir. The "direction" property determines the reading direction of the widget that controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is to handle localization for languages with right-to-left reading directions. Generally, applications will use the default reading direction, except for containers that are arranged in an order that is explicitly visual rather than logical (such as buttons for text justification). The values of dir must be one of the GTK Text Direction Constants.

If the direction is set to gtk.TEXT_DIR_NONE, then the value set by the gtk.widget.set_default_direction() function will be used.

gtk.Widget.get_direction

    def get_direction()

Returns :

the reading direction for the widget.

The get_direction() method returns the reading direction for the widget. See the set_direction() method for more information.

gtk.Widget.shape_combine_mask

    def shape_combine_mask(shape_mask, offset_x, offset_y)

`shape_mask` :	the shape to be added.
`offset_x` :	the X position of shape mask with respect to the widget's `gtk.gdk.Window`.
`offset_y` :	Y position of shape mask with respect to the widget's `gtk.gdk.Window`.

The shape_combine_mask() method sets a shape for the widget's gtk.gdk.Window using the mask specified by shape_mask at the location specified by offset_x and offset_y. This allows for transparent windows etc., see the gtk.gdk.Window.shape_combine_mask() method for more information.

gtk.Widget.reset_shapes

    def reset_shapes()

The reset_shapes() method recursively resets the shapes of the widget and its descendants.

gtk.Widget.path

    def path()

Returns :

the widget's path

The path() method returns the full path to the widget. The path is simply the name of a widget and all its parents in the container hierarchy, separated by periods. The name of a widget comes from the get_name() method. Paths are used to apply styles to a widget in gtkrc configuration files. Widget names are the type of the widget by default (e.g. "GtkButton") or can be set to an application-specific value with the set_name() method. By setting the name of a widget, you allow users or theme authors to apply styles to that specific widget in their gtkrc file.

gtk.Widget.class_path

    def class_path()

Returns :

the widget's class path

The class_path() method is similar to the path() method, but does not use a custom name set with the set_name() (e.g. always uses "GtkButton" even if a custom name is available).

gtk.Widget.list_mnemonic_labels

    def list_mnemonic_labels()

Returns :

the list of mnemonic labels

Note

This method is available in PyGTK 2.4 and above.

The list_mnemonic_labels() method returns a list of the widgets, normally labels, for which this widget is a the target of a mnemonic (see for example, the gtk.Label.set_mnemonic_widget() method).

gtk.Widget.add_mnemonic_label

    def add_mnemonic_label(label)

label :

a gtk.Widget that acts as a mnemonic label.

Note

This method is available in PyGTK 2.4 and above.

The add_mnemonic_label() method adds the widget specified by label to the list of mnemonic labels for the widget.(See the list_mnemonic_labels() method for more detail).

gtk.Widget.remove_mnemonic_label

    def remove_mnemonic_label(label)

label :

a gtk.Widget that was previously set as a mnemonic label.

Note

This method is available in PyGTK 2.4 and above.

The remove_mnemonic_label() method removes the widget specified by label from the list of mnemonic labels for the widget. (See the list_mnemonic_labels() method). label must have previously been added to the list with the add_mnemonic_label().

gtk.Widget.menu_get_for_attach_widget

    def menu_get_for_attach_widget()

Returns :

a list of menus attached to this widget.

Note

This method is available in PyGTK 2.6 and above.

The menu_get_for_attach_widget() method returns a list of the menus that are attached to this widget.

gtk.Widget.set_activate_signal

    def set_activate_signal(signal_name)

signal_name :

a signal name

Note

This method is available in PyGTK 2.8 and above.

The set_activate_signal() method sets the signal specified by signal_name as the signal to be emitted when the widget is activated for example by a call to the activate() method.

gtk.Widget.set_set_scroll_adjustments_signal

    def set_set_scroll_adjustments_signal(signal_name)

signal_name :

a signal name

Note

This method is available in PyGTK 2.8 and above.

The set_scroll_adjustments_signal() method sets the signal specified by signal_name as the signal to be emitted when the widget has its scroll adjustments set for example by a call to the set_scroll_adjustments() method.

gtk.Widget.get_action

    def get_action()

Returns :

the gtk.Action that a widget is a proxy for, or None, if it is not attached to an action.

Note

This method is available in PyGTK 2.10 and above.

The get_action() method returns the gtk.Action that widget is a proxy for. See also the gtk.Action.get_proxies() method.

gtk.Widget.drag_dest_set_track_motion

    def drag_dest_set_track_motion(track_motion)

track_motion :

if True accept all targets

Note

This method is available in PyGTK 2.10 and above.

The drag_dest_set_track_motion() method tells the widget to emit "drag-motion" and "drag-leave" events regardless of the targets and the gtk.DEST_DEFAULT_MOTION flag.

This may be used when a widget wants to do generic actions regardless of the targets that the source offers.

gtk.Widget.drag_dest_get_track_motion

    def drag_dest_get_track_motion()

Returns :

True if the widget always emits "drag-motion events"

Note

This method is available in PyGTK 2.10 and above.

The drag_dest_get_track_motion() method returns True if the widget has been configured to always emit "drag-motion" signals.

gtk.Widget.is_composited

    def is_composited()

Returns :

True if the widget can rely on its alpha channel being drawn correctly.

Note

This method is available in PyGTK 2.10 and above.

`offset_y` :	Y position of `shape_mask` with respect to the widget's window.

Note

This method is available in PyGTK 2.10 and above.

The input_shape_combine_mask() method sets an input shape for this widget's gtk.gdk.Window. This allows for windows that react to a mouse click in a nonrectangular region, see the gtk.gdk.Window.input_shape_combine_mask() method for more information.

gtk.Widget.get_activate_signal

    def get_activate_signal()

Returns :

a signal name

Note

This method is available in PyGTK 2.10 and above.

The get_activate_signal() method returns the name of the signal that is emitted when the widget is activated for example by a call to the activate() method. See the set_activate_signal() method for more information.

gtk.Widget.error_bell

    def error_bell()

Note

This method is available in PyGTK 2.12 and above.

The error_bell() method notifies the user about an input-related error on this widget. If the GtkSettings:gtk-error-bell setting is True, it calls gtk.gdk.Window.beep(), otherwise it does nothing. Note that the effect of gtk.gdk.Window.beep() can be configured in many ways, depending on the windowing backend and the desktop environment or window manager that is used.

gtk.Widget.get_has_tooltip

    def get_has_tooltip()

Returns :

the current value of has-tooltip on widget.

Note

This method is available in PyGTK 2.12 and above.

gtk.Widget.get_tooltip_window

    def get_tooltip_window()

Returns :

the gtk.Window of the current tooltip.

Note

This method is available in PyGTK 2.12 and above.

The get_tooltip_window() method returns the gtk.Window of the current tooltip. This can be the gtk.Window created by default, or the custom tooltip window set using gtk.Widget.set_tooltip_window().

gtk.Widget.keynav_failed

    def keynav_failed(direction)

`direction` :	direction of focus movement.
Returns :	`True` if stopping keyboard navigation is fine, `False` if the emitting widget should try to handle the keyboard navigation attempt in its parent container(s).

Note

This method is available in PyGTK 2.12 and above.

The keynav_failed() should be called whenever keyboard navigation within a single widget hits a boundary. The function emits the GtkWidget::keynav-changed signal on the widget and its return value should be interpreted in a way similar to the return value of gtk.Widget.child_focus():

When True is returned, stay in the widget, the failed keyboard navigation is Ok and/or there is nowhere we can/should move the focus to.

When False is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling gtk_widget_child_focus() on the widget's toplevel.

The default ::keynav-failed handler returns True for gtk.DIR_TAB_FORWARD and gtk.DIR_TAB_BACKWARD. For the other values of GtkDirectionType, it looks at the GtkSettings:gtk-keynav-cursor-only" setting and returns False if the setting is True This way the entire user interface becomes cursor-navigatable on input devices such as mobile phones which only have cursor keys but no tab key.

Whenever the default handler returns True, it also calls gtk.Widget.error_bell() to notify the user of the failed keyboard navigation.

A use case for providing an own implementation of ::keynav-failed (either by connecting to it or by overriding it) would be a row of GtkEntry widgets where the user should be able to navigate the entire row with the cursor keys, as e.g. known from user interfaces that require entering license keys.

gtk.Widget.modify_cursor

    def modify_cursor(primary, secondary)

`primary` :	the color to use for primary cursor (does not need to be allocated), or `None` to undo the effect of previous calls to of `gtk.Widget.modify_cursor`().
`secondary` :	the color to use for secondary cursor (does not need to be allocated), or `None` to undo the effect of previous calls to of `gtk.Widget.modify_cursor`().

Note

This method is available in PyGTK 2.12 and above.

The modify_cursor() sets the cursor color to use in a widget, overriding the GtkWidget:cursor-color and GtkWidget:secondary-cursor-color style properties. All other style values are left untouched. See also gtk.Widget.modify_style().

    def set_tooltip_markup(markup)

markup :

the contents of the tooltip for widget, or None

Note

This method is available in PyGTK 2.12 and above.

The set_tooltip_markup() sets markup as the contents of the tooltip, which is marked up with the Pango text markup language. This function will take care of setting GtkWidget:has-tooltip to True and of the default handler for the GtkWidget::query-tooltip signal. See also the GtkWidget:tooltip-markup property and gtk.Tooltip.set_markup().

gtk.Widget.set_tooltip_text

    def set_tooltip_text(text)

text :

the contents of the tooltip for widget, or None

Note

This method is available in PyGTK 2.12 and above.

gtk.Widget.set_tooltip_window

    def set_tooltip_window(custom_window)

custom_window :

a gtk.Window, or None

Note

This method is available in PyGTK 2.12 and above.

The set_tooltip_window() replaces the default, usually yellow, window used for displaying tooltips with custom_window. GTK+ will take care of showing and hiding custom_window at the right moment, to behave likewise as the default tooltip window. If custom_window is None, the default tooltip window will be used.

Note

You have to connect to the "query-tooltip" signal a callback to decide if the custom_window should be shown or not, return True if you want to show the custom_window, False otherwise. You have also to set the property "has-tooltip" to True or the "query-tooltip" signal will not be emitted.

gtk.Widget.trigger_tooltip_query

    def trigger_tooltip_query()

Note

This method is available in PyGTK 2.12 and above.

The trigger_tooltip_query() triggers a tooltip query on the display where the toplevel of widget is located. See gtk.tooltip_trigger_tooltip_query() for more information.

gtk.Widget.get_snapshot

    def get_snapshot(clip_rect)

`clip_rect` :	a `gtk.gdk.Rectangle` or `None`.
Returns :	The `gtk.gdk.PixmapWindow` snapshot of the widget.

Note

This method is available in PyGTK 2.14 and above.

The get_snapshot() method creates a gtk.gdk.Pixmap of the contents of the widget and its children.

Works even if the widget is obscured. The depth and visual of the resulting pixmap is dependent on the widget being snapshot and likely differs from those of a target widget displaying the pixmap. The function gtk.gdk.Pixbuf.get_from_drawable() can be used to convert the pixmap to a visual independant representation.

The snapshot area used by this function is the widget's allocation plus any extra space occupied by additional windows belonging to this widget (such as the arrows of a spin button). Thus, the resulting snapshot pixmap is possibly larger than the allocation.

If clip_rect is non-None, the resulting pixmap is shrunken to match the specified clip_rect. The (x,y) coordinates of clip_rect are interpreted widget relative. If width or height of clip_rect are 0 or negative, the width or height of the resulting pixmap will be shrunken by the respective amount. For instance a clip_rect { +5, +5, -10, -10 } will chop off 5 pixels at each side of the snapshot pixmap. If non-NULL, clip_rect will contain the exact widget-relative snapshot coordinates upon return. A clip_rect of { -1, -1, 0, 0 } can be used to preserve the auto-grown snapshot area and use clip_rect as a pure output parameter.

The returned pixmap can be None, if the resulting clip_area was empty.

gtk.Widget.get_window

    def get_window()

Returns :

the widget's gtk.gdk.Window .

Note

This method is available in PyGTK 2.14 and above.

gtk.Widget.send_focus_change

    def send_focus_change(event)

`event` :	a FOCUS_CHANGE `gtk.gdk.Event`.
Returns :	the return value from the event signal emission: `True` if the event was handled, and `False` otherwise.

Note

This method is available in PyGTK 2.22 and above.

The send_focus_change() method ends the focus change event to the widget.

This method is not meant to be used by applications. The only time it should be used is when it is necessary for a gtk.Widget to assign focus to a widget that is semantically owned by the first widget even though it's not a direct child - for instance, a search entry in a floating window similar to the quick search in gtk.TreeView.

gtk.Widget.set_realized

gtk.Widget.get_requisition

    def get_requisition(requisition)

Returns :

a gtk.Requisition.

Note

This method is available in PyGTK 2.22 and above.

The get_requisition() method retrieves the widget's requisition.

This method should only be used by widget implementations in order to figure whether the widget's requisition has actually changed after some internal state change (so that they can call queue_resize() instead of gtk.Widget.queue_draw()).

gtk.Widget.style_attach

    def style_attach()

Note

This method is available in PyGTK 2.22 and above.

The style_attach() method attaches the widget's gtk.Style to the widget's gtk.gdk.Window. It is a replacement for the gtk.Style.attach() method and should only ever be called in a derived widget's "realize" implementation which does not chain up to its parent class' "realize" implementation, because one of the parent classes (finally gtk.Widget) would attach the style itself.

has_window :

True if the widget has a window, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

The set_has_window() method specifies whether the widget has a gtk.gdk.Window of its own. Note that all realized widgets have a non-None "window" (get_window() never returns a None window when a widget is realized), but for many of them it's actually the gtk.gdk.Window of one of its parent widgets. Widgets that do not create a window for themselves in their "realize" implementation must announce this by calling this function with has_window = False.

gtk.Widget.get_has_window

    def get_has_window()

Returns :

True if widget has a window, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

The get_receives_default() method determines whether the widget is alyways treated as default widget withing its toplevel when it has the focus, even if another widget is the default.

The effective sensitivity of a widget is however determined by both its own and its parent widget's sensitivity. See is_sensitive().

gtk.Widget.get_sensitive

    def get_sensitive()

Returns :

True if the widget is sensitive, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

    def set_visible(visible)

visible :

True if the widget should be shown, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

The set_visible() method sets the visibility state of the widget. Note that setting this to True doesn't mean the widget is actually viewable, see get_visible().

gtk.Widget.get_visible

    def get_visible()

Returns :

True if the widget is visible, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

gtk.Widget.set_window

    def set_window(window)

window :

a gtk.gdk.Window.

Note

This method is available in PyGTK 2.22 and above.

The set_window() method sets the widget's window. This method should only be used in a widget's "realize" implementation. The window passed is usually either a new window or the window of its parent widget as returned by get_parent_window().

Widgets must indicate whether they will create their own gtk.gdk.Window by calling set_has_window(). This is usually done in the widget's init() method.

gtk.Widget.has_default

    def has_default()

Returns :

True if widget is the current default widget within its toplevel, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

The has_grab() method determines whether the widget is currently grabbing events, so it is the only widget receiving input events (keyboard and mouse).

gtk.Widget.is_sensitive

    def is_sensitive()

Returns :

True if the widget is effectively sensitive, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

The is_sensitive() method returns the widget's effective sensitivity, which means it is sensitive itself and also its parent widget is sensntive.

gtk.Widget.is_toplevel

    def is_toplevel()

Returns :

True if the widget is a toplevel, False otherwise.

Note

This method is available in PyGTK 2.22 and above.

Functions

gtk.widget_push_colormap

    def gtk.widget_push_colormap(cmap)

cmap :

a gtk.gdk.Colormap

The gtk.widget_push_colormap() function pushes the gtk.gdk.Colormap specified by cmap onto a global stack of colormaps. The topmost colormap on the stack will be used when creating widgets. Remove cmap with the gtk.widget_pop_colormap() function. There's little reason to use this function.

gtk.widget_push_composite_child

    def gtk.widget_push_composite_child()

The gtk.widget_push_composite_child() function creates all new widgets as composite children until the corresponding gtk.widget_pop_composite_child() function call. A composite child is a child that's an implementation detail of the container it's inside and should not be visible to people using the container. Composite children aren't treated differently (but see the gtk.Container.foreach() method vs. the gtk.Container.forall() method), but e.g. GUI builders might want to treat them in a different way.

gtk.widget_pop_composite_child

    def gtk.widget_pop_composite_child()

The gtk.widget_pop_composite_child() function cancels the effect of a previous call to the gtk.widget_push_composite_child() function.

gtk.widget_pop_colormap

    def gtk.widget_pop_colormap()

The gtk.widget_pop_colormap() function removes the gtk.gdk.Colormap on the top of the global stack of colormaps. This function reverses the effect of the gtk.widget_push_colormap() function.

    def gtk.widget_get_default_style()

Returns :

the default gtk.Style

The gtk.widget_get_default_style() function returns the default gtk.Style used by all newly created widgets

gtk.widget_set_default_colormap

    def gtk.widget_set_default_colormap(colormap)

colormap :

a gtk.gdk.Colormap object

The gtk.widget_set_default_colormap() function sets the default gtk.gdk.Colormap to use when creating widgets to the value specified by colormap. The gtk.widget_push_colormap() function is a better function to use if you only want to affect a few widgets, rather than all widgets.

gtk.widget_get_default_colormap

    def gtk.widget_get_default_colormap()

Returns :

the default gtk.gdk.Colormap object

The gtk.widget_get_default_colormap() function returns the default gtk.gdk.Colormap used when creating new widgets.

gtk.widget_set_default_direction

    def gtk.widget_set_default_direction(dir)

dir :

the new default direction - either gtk.TEXT_DIR_RTL or gtk.TEXT_DIR_LTR.

The gtk.widget_set_default_direction() function sets the default text direction to the value specified by dir. The value of dir must be either gtk.TEXT_DIR_RTL or gtk.TEXT_DIR_LTR. The default text direction is used for widgets that have not had a text direction set by the set_direction() method.

gtk.widget_get_default_direction

    def gtk.widget_get_default_direction()

Returns :

the default text direction

The gtk.widget_get_default_direction() function returns the default text direction as set by the gtk.widget_set_default_direction() function.

gtk.widget_class_list_style_properties

    def gtk.widget_class_list_style_properties(widget)

`widget` :	a `gtk.Widget`
Returns :	a list of style properties as GParam objects

Note

This function is available in PyGTK 2.4 and above.

The gtk.widget_class_list_style_properties() function returns a list of the style properties of the gtk.Widget specified by widget. The list contains a GParam object for each style property.

a string specifying the name of the property
an object specifying the property type
a string specifying the nickname for the property or None
a string specifying the short description for the property or None

The last item must be a integer containing a combination of the GObject Param Flag Constants. Additional tuple items (if needed) are inserted between the fourth item and the last item depending on the property type:

`gobject.TYPE_CHAR`	minimum, maximum and default values

    def callback(widget, event, user_param1, ...)

`widget` :	the widget that received the signal
`event` :	the event that triggered the signal
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)
Returns :	`True` to stop other handlers from being invoked for the event. `False` to propagate the event further.

The "button-press-event" signal is emitted when a mouse button is pressed.

Returns :	`True` to stop other handlers from being invoked for the event. `False` to propagate the event further.

Note

This signal is available in GTK+ 2.4 and above.

The "can-activate-accel" signal is emitted when an accelerator is about to activate widget. The handler determines if the accelerator that activates the signal identified by signal_id can currently be activated. This signal is present to allow applications and derived widgets to override the default GtkWidget handling for determining whether an accelerator can be activated.

The "child-notify" gtk.Widget Signal

    def callback(widget, child_property, user_param1, ...)

`widget` :	the widget that received the signal
`child_property` :	the name of a child property
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "child-notify" signal is emitted when child_property is changed.

Child properties are available with objects derived from gtk.Container. Those properties are not specific to either the container or the child widget but to their relation. For example, the "pack-type" property of gtk.Box or the "menu-label" property of gtk.Notebook are child properties.

The "client-event" gtk.Widget Signal

    def callback(widget, event, user_param1, ...)

`widget` :	the widget that received the signal
`event` :	the event that triggered the signal
`user_param1` :	the first user parameter (if any) specified with the `connect`() method

`widget` :	the widget that received the signal
`event` :	the event that triggered the signal
`user_param1` :	the first user parameter (if any) specified with the `connect`() method

`...` :	additional user parameters (if any)
Returns :	`True` to stop other handlers from being invoked for the event. `False` to propagate the event further.

The "destroy-event" signal is emitted when a gtk.gdk.Window is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time.

The "direction-changed" gtk.Widget Signal

    def callback(widget, direction, user_param1, ...)

`widget` :	the widget that received the signal
`direction` :	the previous direction: `gtk.TEXT_DIR_NONE`, `gtk.TEXT_DIR_LTR` or `gtk.TEXT_DIR_RTL`

The "drag-begin" gtk.Widget Signal

    def callback(widget, drag_context, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "drag-begin" signal is emitted when the user initiates a drag operation on widget. A typical reason to connect to this signal is to set up a custom drag icon with the drag_source_set_icon() method.

The "drag-data-delete" gtk.Widget Signal

    def callback(widget, drag_context, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "drag-data-delete" signal is emitted when the drag completes a move operation and requires the source data to be deleted. The signal handler is responsible for deleting the data that has been dropped.

The "drag-data-get" gtk.Widget Signal

    def callback(widget, drag_context, selection_data, info, timestamp, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`selection_data` :	a `gtk.SelectionData` object
`info` :	an integer ID for the drag
`timestamp` :	the time of the drag event
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "drag-data-get" signal is emitted when a drag operation completes that copies data or when a drag drop occurs using the gtk.gdk.DRAG_PROTO_ROOTWIN protocol. The drag source revceives this signal when the drag destination requests the data using the drag_get_data() method. The handler needs to fill selection_data with the data in the format specified by the target associated with info.

The "drag-data-received" gtk.Widget Signal

    def callback(widget, drag_context, x, y, selection_data, info, timestamp, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`x` :	the X position of the drop
`y` :	the Y position of the drop
`selection_data` :	a `gtk.SelectionData` object
`info` :	an integer ID for the drag
`timestamp` :	the time of the drag event
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "drag-data-received" signal is emitted when the drag destination receives the data from the drag operation. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call the gtk.gdk.DragContext.drag_status() method and not finish the drag. If the data was received in response to a "drag-drop" signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call the gtk.gdk.DragContext.finish() method, setting the success parameter to True if the data was processed successfully.

The "drag-drop" gtk.Widget Signal

    def callback(widget, drag_context, x, y, timestamp, user_param1, ...)

`widget` :	the widget that received the signal

`timestamp` :	the time of the drag event
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)
Returns :	`True` if the cursor is in a drop zone

The "drag-drop" signal is emitted when the drag initiates a drop operation on the destination widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns False and no further processing is necessary. Otherwise, the handler returns True. In this case, the handler must ensure that the gtk.gdk.DragContext.finish() method is called to let the source know that the drop is done. The call to the gtk.gdk.DragContext.finish() method can be done either directly or in a "drag-data-received" handler that gets triggered by calling the drag_get_data() method to receive the data for one or more of the supported targets.

The "drag-end" gtk.Widget Signal

    def callback(widget, drag_context, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "drag-end" signal is emitted when the drag operation is completed. A typical reason to connect to this signal is to undo things done in a "drag-begin" handler.

The "drag-failed" gtk.Widget Signal

    def callback(widget, drag_context, result, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`result` :	the result of the drag operation.
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)
Returns :	`True` if the failed drag operation has been already handled.

The "drag-failed" signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DND operation based on the type of error, it returns True is the failure has been already handled (not showing the default "drag operation failed" animation), otherwise it returns False.

The "drag-leave" gtk.Widget Signal

    def callback(widget, drag_context, timestamp, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`timestamp` :	the time of the drag event
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "drag-leave" signal is emitted when the drag operation moves off of a drop target widget. A typical reason to connect to this signal is to undo things done in a "drag-motion" handler, e.g. undo highlighting with the drag_unhighlight() method.

The "drag-motion" gtk.Widget Signal

    def callback(widget, drag_context, x, y, timestamp, user_param1, ...)

`widget` :	the widget that received the signal
`drag_context` :	the `gtk.gdk.DragContext`
`x` :	the X position of the drop
`y` :	the Y position of the drop
`timestamp` :	the time of the drag event
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)
Returns :	`True` if the cursor is in a drop zone

The "drag-motion" signal is emitted when the drag operation moves over a drop target widget. The signal handler must determine if the cursor position is in a drop zone or not. If it is not in a drop zone, it should return False and no further processing is necessary. Otherwise, the handler should return True. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling the gtk.gdk.DragContext.drag_status() method. If the decision to accept or reject the drop can't be made based solely on the cursor position and the type of the data, the handler may inspect the dragged data by calling the drag_get_data() method and defer the gtk.gdk.DragContext.drag_status() method call to the "drag-data-received" handler.

Note

There is no "drag-enter" signal. The drag receiver has to keep track of any "drag-motion" signals received since the last "drag-leave" signal. The first "drag-motion" signal received after a "drag_leave" signal should be treated as an "enter" signal. Upon an "enter", the handler will typically highlight the drop site with the drag_highlight() method.
