DropControllerMotion

Object Hierarchy:

Description:

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

An event controller tracking the pointer during Drag-and-Drop operations.

It is modeled after [class@Gtk.EventControllerMotion] so if you have used that, this should feel really familiar.

This controller is not able to accept drops, use [class@Gtk.DropTarget] for that purpose.
