UIElement3D.MouseLeave Event


Occurs when the mouse pointer leaves the bounds of this element.

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

public event MouseEventHandler MouseLeave

MouseLeave 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.

Although MouseLeave tracks when the mouse leaves an element, this event more literally reports that the IsMouseOver property value has changed from true to false on this element.

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

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