GesturePan

#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.

Constructors

this this(GtkGesturePan* gtkGesturePan, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(Widget widget, GtkOrientation orientation): Returns a newly created #GtkGesture that recognizes pan gestures.
