UIElement3D.StylusLeave Event


Occurs when the stylus leaves the bounds of the element.

Namespace:   System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

abstract StylusLeave : IEvent<StylusEventHandler,
override StylusLeave : IEvent<StylusEventHandler,

StylusLeave is a Routed Events Overview that uses the direct event handling routing strategy. Direct routed events are not raised along a route; instead, they are handled in the same element where they are raised. However, they do enable other aspects of routed event behavior, such as event triggers in styles.

Although StylusLeave tracks when the stylus leaves the bounds of an element, this event more literally reports that the IsStylusOver property value has changed from true to false on this element.

This event creates an alias for the Stylus.StylusLeave attached event for this class, so that StylusLeave is part of the class members list when UIElement3D is inherited as a base element. Event handlers that are attached to the StylusLeave event are attached to the underlying Stylus.StylusLeave attached event and receive the same event data instance.

Touch, mouse, and stylus input exist in a particular relationship. For more information, see Touch Input Support in Windows Vista and Input Overview.

StylusLeave is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
