Widget.connectGrabNotify

gtk widget Widget

Connect to GrabNotify signal.

The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.

A widget is shadowed by a gtk.widget.Widget.grabAdd when the topmost grab widget in the grab stack of its window group is not its ancestor.
