Syntax

public class PinchGestureRecognizer : GestureRecognizer<float>, IGestureRecognizer

Methods

Recognize(ReadOnlySpan<AppUITouch>)

Main method to recognize a gesture.

A concrete implementation of a gesture recognizer should override this method to recognize a gesture. The implementation should also assume that this method will be called every frame.

Declaration

public override void Recognize(ReadOnlySpan<AppUITouch> appuiTouches)

Parameters

Type	Name	Description
ReadOnlySpan<AppUITouch>	appuiTouches	The current touch inputs for the current frame.

Overrides

GestureRecognizer<float>.Recognize(ReadOnlySpan<AppUITouch>)

Remarks

Sometimes, touch inputs can be lost from a frame to another (no AppUITouch event with an Ended or Canceled phase will be sent). The concrete implementation must aknowledge this and reset its state accordingly.

Reset()

Resets the gesture recognizer to its initial state.

Declaration

public override void Reset()

Overrides

GestureRecognizer<float>.Reset()
