Enumeration
Gdk.TouchpadGesturePhase
Description [src]
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.
