GestureRecognizer.CanBeDoubleTap(PointerPoint) GestureRecognizer.CanBeDoubleTap(PointerPoint) GestureRecognizer.CanBeDoubleTap(PointerPoint) GestureRecognizer.CanBeDoubleTap(PointerPoint) GestureRecognizer.CanBeDoubleTap(PointerPoint) Method

Definition

Identifies whether a tap can still be interpreted as the second tap of a double tap gesture.

public : Platform::Boolean CanBeDoubleTap(PointerPoint value)
bool CanBeDoubleTap(PointerPoint value) const;
public bool CanBeDoubleTap(PointerPoint value)
Public Function CanBeDoubleTap(value As PointerPoint) As bool
var bool = gestureRecognizer.canBeDoubleTap(value);

Parameters

value
PointerPoint PointerPoint PointerPoint

The last input pointer.

Returns

bool bool bool

True if a UI element supports the double tap gesture and the time threshold to complete the gesture has not been crossed; otherwise false.

Remarks

This method supports GestureRecognizer object pool management, where GestureRecognizer objects are dynamically assigned to a set of UI elements.

Specifically, GestureRecognizer objects can be recycled for UI elements that do not support or can no longer process a double tap gesture. For example, if CanBeDoubleTap returns true for the most recent PointerPoint, it’s not safe to recycle the GestureRecognizer because a double tap is still a viable interaction based on subsequent input. If CanBeDoubleTap returns false, the GestureRecognizer can be safely recycled.

This method is not required if GestureRecognizer object pool management is not implemented.
