Enumeration
PhocTouchpadGesturePhase
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.
