drag_set_icon_surface

Sets surface as the icon for a given drag.

GTK+ retains references for the arguments, and will release them when they are no longer needed.

To position the surface relative to the mouse, use set_device_offset on surface. The mouse cursor will be positioned at the (0,0) coordinate of the surface.

Parameters:

context	the context for a drag (This must be called with a context for the source side of a drag)
surface	the surface to use as icon
