create-menu-proxy
This signal is emitted when the toolbar needs information from the tool
item about whether the item should appear in the toolbar overflow menu.
In response the tool item should either
-
call set_proxy_menu_item() with
a null pointer and return true
to indicate that the item should not appear in the overflow menu.
-
call set_proxy_menu_item() with
a new menu item and return true, or return
false to indicate that the signal was not handled by
the item. This means that the item will not appear in the overflow menu
unless a later handler installs a menu item.
The toolbar may cache the result of this signal. When the tool item
changes how it will respond to this signal it must call
rebuild_menu() to invalidate the
cache and ensure that the toolbar rebuilds its overflow menu.
