Widget.setClip

Sets the widget’s clip. This must not be used directly, but from within a widget’s size_allocate method. It must be called after [gtk.widget.Widget.setAllocation] (or after chaining up to the parent class), because that function resets the clip.

The clip set should be the area that widget draws on. If widget is a #GtkContainer, the area must contain all children's clips.

If this function is not called by widget during a ::size-allocate handler, the clip will be set to widget's allocation.
