System.String gestureName The gesture name.

System.Action forcedFinish The callback that is executed when the gesture is forcibly deactivated.

Returns

GestureDeactivationToken

CanActivateGesture(UIElement, String)

Gets a value indicating whether the candidate gesture can be activated. The gesture cannot be activated if there is already an active gesture and the transition is not allowed.

Declaration

public static bool CanActivateGesture(UIElement element, string candidateGestureName)

Parameters

System.Windows.UIElement element

System.String candidateGestureName
