Description

A gtk.MenuShell is the abstract base class used to derive the gtk.Menu and gtk.MenuBar subclasses. A gtk.MenuShell is a container of gtk.MenuItem objects arranged in a list which can be navigated, selected, and activated by the user to perform application functions. A gtk.MenuItem can have a submenu associated with it, allowing for nested hierarchical menus.

Methods

gtk.MenuShell.append

    def append(child)

child :

The gtk.MenuItem to add.

The append() method adds a new gtk.MenuItem specified by child to the end of the menu shell's item list.

gtk.MenuShell.prepend

    def prepend(child)

child :

The gtk.MenuItem to add.

The prepend() method adds a new gtk.MenuItem specified by child to the beginning of the menu shell's item list.

gtk.MenuShell.insert

    def insert(child, position)

child :

The gtk.MenuItem to add.

position :

The position in the item list where child should be added. Positions are numbered starting from 0.

The insert() method adds a new gtk.MenuItem specified by child to the menu shell's item list at the position specified by position.

gtk.MenuShell.deactivate

    def deactivate()

The deactivate() method deactivates the menu shell. Typically this results in the menu shell being removed from the screen.

gtk.MenuShell.select_item

    def select_item(menu_item)

menu_item :

The gtk.MenuItem to select.

The select_item() method selects the menu item specified by menu_item from the menu shell.

gtk.MenuShell.deselect

    def deselect()

The deselect() method deselects the currently selected item from the menu shell, if any.

gtk.MenuShell.activate_item

    def activate_item(menu_item, force_deactivate)

menu_item :

The gtk.MenuItem to activate.

force_deactivate :

If True, force the deactivation of the menu shell after the menu item is activated.

The activate_item() method activates the menu item specified by menu_item. If force_deactivate is True the menushell is forcibly deactivated after menu_item is activated.

gtk.MenuShell.select_first

    def select_first(search_sensitive)

search_sensitive :

if True, search for the first selectable menu item, otherwise select nothing if the first item isn't sensitive.

Note

This method is available in PyGTK 2.2 and above.

The select_first() method selects the first visible or selectable child of the menu shell if search_sensitive is True. Don't select tearoff items unless the only item is a tearoff item. If search_sensitive is False select nothing if the first item isn't sensitive. search_sensitive should be False if the menu is being popped up initially.

gtk.MenuShell.cancel

    def cancel()

Note

This method is available in PyGTK 2.4 and above.

The cancel() method cancels the selection within the menu shell.

gtk.MenuShell.set_take_focus

    def set_take_focus(take_focus)

take_focus :

if True, the menu shell should take the keyboard focus on popup.

Note

This method is available in PyGTK 2.8 and above.

The set_take_focus() method sets the "take-focus" property to the value of take_focus. If take_focus is True the menu shell will take the keyboard focus so that it will receive all keyboard events to enable keyboard navigation in menus.

Setting the "take-focus" property to False is useful only for special applications like virtual keyboard implementations which should not take keyboard focus.

The "take-focus" state of a menu or menu bar is automatically propagated to submenus whenever a submenu is popped up, so you don't have to worry about recursively setting it for your entire menu hierarchy. Only when programmatically picking a submenu and popping it up manually, should the "take-focus" property of the submenu be set explicitly.

Note that setting it to False has side-effects:

  • If the focus is in some other app, it keeps the focus and keyboard navigation in the menu doesn't work. Consequently, keyboard navigation on the menu will only work if the focus is on some toplevel owned by the onscreen keyboard.

  • To avoid confusing the user, menus with the "take-focus" property set to False should not display mnemonics or accelerators, since they may not work.

Also see the gtk.gdk.keyboard_grab() function for more information.

gtk.MenuShell.get_take_focus

    def get_take_focus()

Returns :

True if the men shell will take keyboard foucs on popup.

Note

This method is available in PyGTK 2.8 and above.

The get_take_focus() method returns the value of the "take-focus" property. See the set_take_focus() method for more information.

Signals

The "activate-current" gtk.MenuShell Signal

    def callback(menushell, force_hide, user_param1, ...)

menushell :

the menushell that received the signal

force_hide :

if True, hide the menu after activating the menu item.

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "activate-current" signal is emitted to activate the current menu item in the menushell.

The "cancel" gtk.MenuShell Signal

    def callback(menushell, user_param1, ...)

menushell :

the menushell that received the signal

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "cancel" signal is emitted to cancel the selection in the menushell. Also causes the "selection-done" signal to be emitted.

The "cycle-focus" gtk.MenuShell Signal

    def callback(menushell, user_param1, ...)

menushell :

the menushell that received the signal

direction :

the direction to cycle the focus; one of: gtk.DIR_TAB_FORWARD, gtk.DIR_TAB_BACKWARD, gtk.DIR_UP, gtk.DIR_DOWN, gtk.DIR_LEFT or gtk.DIR_RIGHT

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "cycle-focus" signal is emitted when an action occurs requesting the focus move to the next menubar.

The "deactivate" gtk.MenuShell Signal

    def callback(menushell, user_param1, ...)

menushell :

the menushell that received the signal

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "deactivate" signal is emitted when the menushell is deactivated.

The "move-current" gtk.MenuShell Signal

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

menushell :

the menushell that received the signal

direction :

the direction to move; one of: gtk.MENU_DIR_PARENT, gtk.MENU_DIR_CHILD, gtk.MENU_DIR_NEXT or gtk.MENU_DIR_PREV

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "move-current" signal is emitted when the current menu item is to be moved in the direction specified by direction which is one of:

gtk.MENU_DIR_PARENT

To the parent menu shell.

gtk.MENU_DIR_CHILD

To the submenu, if any, associated with the item.

gtk.MENU_DIR_NEXT

To the next menu item.

gtk.MENU_DIR_PREV

To the previous menu item.

The "move-selected" gtk.MenuShell Signal

    def callback(menushell, distance, user_param1, ...)

distance :

+1 to move to the next item, -1 to move to the previous

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Note

This signal is available in GTK+ 2.12 and above.

The "move-selected" signal is emitted to move the selection to another item.

the menushell that received the signal

user_param1 :

the first user parameter (if any) specified with the connect() method
