dragDropDone

Inform GDK if the drop ended successfully. Passing false for success may trigger a drag cancellation animation.

This function is called by the drag source, and should be the last call before dropping the reference to the context.

The #GdkDragContext will only take the first [gdk.drag.Drag.dropDone] call as effective, if this function is called multiple times, all subsequent calls will be ignored.
