C# Class Blake.NUI.WPF.Gestures.HoldGestureEngine

Gesture engine that detects the "Hold" gesture. This gesture is defined as a touch down and hold for a (configurable) amount of time. Releasing the touch point or moving it too far before the timeout has been reached will abort the gesture.

See IGestureEngine documentation for details about the behavior.
