### Enumeration

# PhocTouchpadGesturePhase

#### Declaration

    enum Phoc.TouchpadGesturePhase

#### Description [src]

The phase of a touchpad gesture event. All gestures are guaranteed to begin with an event of type `PHOC_TOUCHPAD_GESTURE_PHASE_BEGIN`, followed by a number of `PHOC_TOUCHPAD_GESTURE_PHASE_UPDATE` (possibly 0).

A finished gesture may have 2 possible outcomes, an event with phase `PHOC_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 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 with report the phase `PHOC_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.
