Enum gdk4::TouchpadGesturePhase
source · #[non_exhaustive]pub enum TouchpadGesturePhase {
Begin,
Update,
End,
Cancel,
}
Expand description
Specifies the current state of a touchpad gesture.
All gestures are guaranteed to begin with an event with phase
Begin
, followed by 0 or several events
with phase Update
.
A finished gesture may have 2 possible outcomes, an event with 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
Cancel
, this should be used as a hint
to undo any visible/permanent changes that were done throughout the
progress of the gesture.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Begin
The gesture has begun.
Update
The gesture has been updated.
End
The gesture was finished, changes should be permanently applied.
Cancel
The gesture was cancelled, all changes should be undone.
