gtk.Action — an action which can be triggered by a menu or toolbar item (new in PyGTK 2.4)
|
"activate" | def callback( |
This widget is available in PyGTK 2.4 and above.
A gtk.Action
represents operations that the user can perform, along with some information
how it should be presented in the interface. Each gtk.Action
provides
methods to create icons, menu items and toolbar items representing
itself.
As well as the callback that is called when the action gets activated, the following also gets associated with the action:
The action will also have some state information:
Apart from regular actions, there are toggle actions, which can be
toggled between two states and radio actions, where only one in a group
can be in the "active" state. Other actions can be implemented as gtk.Action
subclasses.
Each gtk.Action
can have
one or more proxy menu items, toolbar buttons or other proxy
widgets. Proxies mirror the state of the action (text label, tooltip, icon,
visible, sensitive, etc), and should change when the action's state
changes. When the proxy is activated, it should activate its action.
gtk.Action(name
, label
, tooltip
, stock_id
)
| a unique name for the gtk.Action |
| the label displayed in menu items and on buttons |
| a tooltip for the action |
| the stock icon to display in widgets representing the action |
Returns : | a new gtk.Action |
This constructor is available in PyGTK 2.4 and above.
Creates a new gtk.Action
object. To add the action to a gtk.ActionGroup
and set the accelerator for the action, call the gtk.ActionGroup.add_action_with_accel()
.
def block_activate()
This method is available in PyGTK 2.16 and above.
The block_activate
() method disable activation signals from the action
This is needed when updating the state of your proxy
gtk.Activatable
widget could result in calling
gtk.Action.activate
(),
this is a convenience function to avoid recursing in those cases (updating toggle state for instance).
def get_gicon()

True
if the action is effectively sensitive i.e. both the
gtk.Action
and
its associated gtk.ActionGroup
are sensitive.
def get_sensitive()
Returns : | True if the action itself
is sensitive. |
This method is available in PyGTK 2.4 and above.
The get_sensitive
() method returns the
value of the "sensitive" property. If "sensitive" is True

)
| the proxy widget |
This method is available in PyGTK 2.4 and above.
The connect_proxy
() method connects the
widget specified by proxy
to the gtk.Action
object as
a proxy. This method synchronizes various properties of the gtk.Action
with the
widget (such as label text, icon, tooltip, etc), and attaches a callback so
that the gtk.Action
is
activated when proxy
is.
If proxy
is already connected to another
gtk.Action
, it
is disconnected first. The gtk.Action
should be
added to a gtk.ActionGroup
before calling this method.
def disconnect_proxy(proxy
)
| the proxy widget |
This method is available in PyGTK 2.4 and above.
The disconnect_proxy
() method
disconnects the widget specified by proxy
from the
gtk.Action
. This
method does not destroy the widget. The gtk.Action
should be
added to a gtk.ActionGroup
before calling this method.
def get_proxies()
Returns : | a list of proxy widgets. |
This method is available in PyGTK 2.4 and above.
The get_proxies
() method returns a list
containing the proxy widgets associated with the gtk.Action
.
def connect_accelerator()
This method is available in PyGTK 2.4 and above.
The connect_accelerator
() method
installs the accelerator for the gtk.Action
if it has
an associated accel path and gtk.AccelGroup
. See
the set_accel_path()
and the set_accel_group()
methods.
Since multiple proxies may independently trigger the
installation of the accelerator, the gtk.Action
counts
the number of times this method has been called and doesn't remove the
accelerator until disconnect_accelerator()
has been called as many times.
def disconnect_accelerator()
This method is available in PyGTK 2.4 and above.
The disconnect_accelerator
() method
undoes the effect of one call to the connect_accelerator()
method.
def block_activate_from(proxy
)
| a proxy widget |
This method is available in PyGTK 2.4 and above.
The block_activate_from
() method
disables calls to the activate()
method by signals on the widget specified by
proxy
. This is used to break notification loops for
things like check or radio actions.
This method is intended for use by gtk.Action
implementations.
def unblock_activate_from(proxy
)
| a proxy widget |
This method is available in PyGTK 2.4 and above.
The unblock_activate_from
() method
re-enables calls to the activate()
method by signals on the widget specified by proxy
.
This undoes the blocking done by the block_activate_from()
method.
This method is intended for use by gtk.Action
implementations.
def get_accel_path()
Returns : | the accelerator path associated with the action
or None |
This method is available in PyGTK 2.6 and above.

() method returns the
accel path for the action or None
if no accel path is
set.
def set_accel_path(accel_path
)
| the accelerator path |
This method is available in PyGTK 2.4 and above.
The set_accel_path
() method sets the
accel path for the action to the value of
accel_path
. All proxy widgets associated with the
action will have this accel path, so that their accelerators are
consistent.
def get_always_show_image()
Returns : | Returns True if the action's menu item proxies always show their image, False otherwise |
This method is available in PyGTK 2.22 and above.
The get_always_show_image
() method returns whether the action's
menu item proxies will ignore the "gtk-menu-images" setting and always show their image, if available.
def set_always_show_image(always_show
)
| If True the action's menu item proxies will always show their image |
This method is available in PyGTK 2.22 and above.
The set_always_show_image
() method sets whether the action's
menu item proxies will ignore the "gtk-menu-images" setting and always show their image, if available.
Use this if the menu item would be useless or hard to use without their image.

)
| a gtk.AccelGroup or None |
This method is available in PyGTK 2.4 and above.

)
| if True make the action
sensitive |
This method is available in PyGTK 2.6 and above.
The set_sensitive
() method sets the
"sensitive" property to the value of sensitive
. Note
that this doesn't necessarily set the effective sensitivity. See the is_sensitive
()
method for more information.

() method sets whether action
is visible when vertical
def set_menu_item_type(visible
)
| the type of menuitem to be created for the action |
This method is available in PyGTK 2.10 and above.
The set_menu_item_type
() method is a
classmethod that sets the type of menuitem to be created for the
action to that specified by type
. This is
useful when using the gtk.UIManager
and you would like to use something other than a gtk.ImageMenuItem
(gtk.Action
) or
a gtk.CheckMenuItem
(gtk.ToogleAction
gtk.RadioAction
).
def set_tool_item_type(visible
)
| the type of toolitem to be created for the action |
This method is available in PyGTK 2.10 and above.
The set_tool_item_type
() method is a
classmethod that sets the type of toolitem to be created for the
action to that specified by type
. This is
useful when using the gtk.UIManager
and you would like to use something other than a gtk.ToolButton
(gtk.Action
) or
a gtk.ToggleToolButton
(gtk.ToogleAction
gtk.RadioAction
).
For example, to use a gtk.MenuToolButton
in a toolbar you would subclass gtk.Action
:
class MenuToolAction(gtk.Action): __gtype_name__ = "MenuToolAction" gobject.type_register(MenuToolAction)
and then call set_tool_item_type
():
MenuToolAction.set_tool_item_type(gtk.MenuToolButton)
You have to create, name and add an instance of
MenuToolAction
to your gtk.ActionGroup
:
actiongroup.add_action(MenuToolAction("my_menutoolaction", "_MTB_label", "do something", None))
The ui description should reference the
MenuToolAction
like:
<toolitem action="my_menutoolaction"/>
After the gtk.UIManager
creates the toolbar including the gtk.MenuToolButton
proxy for the MenuToolAction
, you would have to
create and add a menu to the gtk.MenuToolButton
instance.
This technique can be extended by subclassing gtk.ToolItem
and adding custom widgets to it.
def callback(action
, user_param1
, ...
)
| the gtk.Action that
received the signal |
| the first user parameter (if any) specified
with the connect () |
| additional user parameters (if any) |
This signal is available in PyGTK 2.4 and above.
The "activate" signal is emitted when
action
is activated.
