Sets a paintable to use as icon during DND operations.
The hotspot coordinates determine the point on the icon that gets aligned with the hotspot of the cursor.
If paintable
is null, a default icon is used.
This function can be called before a drag is started, or in a [[email protected]:GtkDragSource:prepare
] or [
[email protected]:GtkDragSource:drag-begin
] signal handler.
