GI.Clutter.Structs.TouchpadPinchEvent

Used for touchpad pinch gesture events. The current state of the gesture will be determined by the phase field.

Each event with phase TouchpadGesturePhaseBegin will report a scale of 1.0, all later phases in the gesture report the current scale relative to the initial 1.0 value (eg. 0.5 being half the size, 2.0 twice as big).

Since: 1.24
