Details

The gdk:drag object represents the source of an ongoing DND operation. A gdk:drag object is created when a drag is started, and stays alive for duration of the DND operation. After a drag has been started with the gdk:drag-begin function, the caller gets informed about the status of the ongoing drag operation with signals on the gdk:drag object.

GTK provides a higher level abstraction based on top of these functions, and so they are not normally needed in GTK applications. See the "Drag and Drop" section of the GTK documentation for more information.
