EventTouchpadPinchProtocol

public protocol EventTouchpadPinchProtocol

The EventTouchpadPinchProtocol protocol exposes the methods and properties of an underlying GdkEventTouchpadPinch instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see EventTouchpadPinch. Alternatively, use EventTouchpadPinchRef as a lighweight, unowned reference if you already have an instance you just want to use.

Generated during touchpad swipe gestures.
