GestureDragRef

public struct GestureDragRef : GestureDragProtocol, GWeakCapturing

GtkGestureDrag is a GtkGesture implementation that recognizes drag operations. The drag operation itself can be tracked throught the GtkGestureDrag::drag-begin, GtkGestureDrag::drag-update and GtkGestureDrag::drag-end signals, or the relevant coordinates be extracted through gtk_gesture_drag_get_offset() and gtk_gesture_drag_get_start_point().

The GestureDragRef type acts as a lightweight Swift reference to an underlying GtkGestureDrag instance. It exposes methods that can operate on this data type through GestureDragProtocol conformance. Use GestureDragRef only as an unowned reference to an existing GtkGestureDrag instance.

  • ptr 
    Untyped pointer to the underlying `GtkGestureDrag` instance.

    For type-safe access, use the generated, typed pointer gesture_drag_ptr property instead.
