gtk:menu-button-align-widget (object)

object -- a gtk:menu-button widget
widget -- a gtk:widget object

The accessor for the align-widget slot gets or sets the parent widget to use to line up the menu with when popped up. Note that the widget argument must contain the menu button itself. Setting it to nil means that the menu will be aligned with the button itself.

Note that this property is only used with menus currently, and not for popovers.
