GesturePanRef

public struct GesturePanRef : GesturePanProtocol, GWeakCapturing

GtkGesturePan is a GtkGesture implementation able to recognize pan gestures, those are drags that are locked to happen along one axis. The axis that a GtkGesturePan handles is defined at construct time, and can be changed through gtk_gesture_pan_set_orientation().

When the gesture starts to be recognized, GtkGesturePan will attempt to determine as early as possible whether the sequence is moving in the expected direction, and denying the sequence if this does not happen.

Once a panning gesture along the expected axis is recognized, the GtkGesturePan::pan signal will be emitted as input events are received, containing the offset in the given axis.

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

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

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