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.
def append(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.
def prepend(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.
def insert(child, position)
| The gtk.MenuItem to
add. |
| 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.
def deactivate()The deactivate() method deactivates the
menu shell. Typically this results in the menu shell being removed from the
screen.
def select_item(menu_item)
| The gtk.MenuItem to
select. |
The select_item() method selects the
menu item specified by menu_item from the menu
shell.
def deselect()The deselect() method deselects the
currently selected item from the menu shell, if any.
def activate_item(menu_item, force_deactivate)
| The gtk.MenuItem to
activate. |
| 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.
def select_first(search_sensitive)
| if True, search for the
first selectable menu item, otherwise select nothing if the first
item isn't sensitive. |
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.
def cancel()This method is available in PyGTK 2.4 and above.
The cancel() method cancels the
selection within the menu shell.
def set_take_focus(take_focus)
| if True, the menu shell should
take the keyboard focus on popup. |
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.
def get_take_focus()Returns : | True if the men shell will
take keyboard foucs on popup. |
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.
def callback(menushell, force_hide, user_param1, ...)
| the menushell that received the signal |
| if True, hide the menu after activating the menu item. |
| the first user parameter (if any) specified
with the connect() |
| additional user parameters (if any) |
The "activate-current" signal is emitted to activate the current menu item in the menushell.
def callback(menushell, user_param1, ...)
| the menushell that received the signal |
| the first user parameter (if any) specified
with the connect() |
| 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.
def callback(menushell, user_param1, ...)
| the menushell that received the signal |
| 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 |
| the first user parameter (if any) specified
with the connect() |
| additional user parameters (if any) |
The "cycle-focus" signal is emitted when an action occurs requesting the focus move to the next menubar.
def callback(menushell, user_param1, ...)
| the menushell that received the signal |
| the first user parameter (if any) specified
with the connect() |
| additional user parameters (if any) |
The "deactivate" signal is emitted when the menushell is deactivated.
def callback(menushell, direction, user_param1, ...)
| the menushell that received the signal |
| the direction to move; one of:
gtk.MENU_DIR_PARENT,
gtk.MENU_DIR_CHILD, gtk.MENU_DIR_NEXT
or gtk.MENU_DIR_PREV |
| the first user parameter (if any) specified
with the connect() |
| 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:
| To the parent menu shell. |
| To the submenu, if any, associated with the item. |
| To the next menu item. |
| To the previous menu item. |
def callback(menushell, distance, user_param1, ...)
| the menushell that received the signal |
| +1 to move to the next item, -1 to move to the previous |
| the first user parameter (if any) specified
with the connect() |
| additional user parameters (if any) |
This signal is available in GTK+ 2.12 and above.
The "move-selected" signal is emitted to move the selection to another item.
def callback(menushell, user_param1, ...)
| the menushell that received the signal |
| the first user parameter (if any) specified
with the connect() |
| additional user parameters (if any) |
The "selection-done" signal is emitted when a selection has been completed within a menu shell.
