present

Present @popup after having processed the GdkPopupLayout rules.

If the popup was previously not showing, it will be shown, otherwise it will change position according to @layout.

After calling this function, the result should be handled in response to the signal@Gdk.Surface::layout signal being emitted. The resulting popup position can be queried using method@Gdk.Popup.get_position_x, method@Gdk.Popup.get_position_y, and the resulting size will be sent as parameters in the layout signal. Use method@Gdk.Popup.get_rect_anchor and method@Gdk.Popup.get_surface_anchor to get the resulting anchors.

Presenting may fail, for example if the @popup is set to autohide and is immediately hidden upon being presented. If presenting failed, the signal@Gdk.Surface::layout signal will not me emitted.
