GdkTouchpadGesturePhase

Specifies the current state of a touchpad gesture. All gestures are guaranteed to begin with an event with phase GDK_TOUCHPAD_GESTURE_PHASE_BEGIN, followed by 0 or several events with phase GDK_TOUCHPAD_GESTURE_PHASE_UPDATE.

A finished gesture may have 2 possible outcomes, an event with phase GDK_TOUCHPAD_GESTURE_PHASE_END will be emitted when the gesture is considered successful, this should be used as the hint to perform any permanent changes.

Cancelled gestures may be so for a variety of reasons, due to hardware or the compositor, or due to the gesture recognition layers hinting the gesture did not finish resolutely (eg. a 3rd finger being added during a pinch gesture). In these cases, the last event will report the phase GDK_TOUCHPAD_GESTURE_PHASE_CANCEL, this should be used as a hint to undo any visible/permanent changes that were done throughout the progress of the gesture.
