Warning
gtk_item_factory_popup has been deprecated since version 2.4 and should not be used in newly-written code. Use GtkUIManager instead.
Pops up the menu constructed from the item factory at (x, y).
The mouse_button parameter should be the mouse button pressed to initiate
the menu popup. If the menu popup was initiated by something other than
a mouse button press, such as a mouse button release or a keypress,
mouse_button should be 0.
The time_ parameter should be the time stamp of the event that
initiated the popup. If such an event is not available, use
gtk_get_current_event_time() instead.
The operation of the mouse_button and the time_ parameter is the same
as the button and activation_time parameters for gtk_menu_popup().
