Description:

[ CCode ( type_id = "gtk_drop_controller_motion_get_type ()" ) ]
public class DropControllerMotion : EventController

DropControllerMotion is an event controller meant for tracking the pointer hovering over a widget during a drag and drop operation.

It is modeled after EventControllerMotion so if you have used that, this should feel really familiar.

The drop controller is not able to accept drops, use DropTarget for that purpose.
