UIElement.StylusEnter Event

Definition

Occurs when the stylus enters the bounds of this element.

public:
 virtual event System::Windows::Input::StylusEventHandler ^ StylusEnter;
public event System.Windows.Input.StylusEventHandler StylusEnter;
member this.StylusEnter : System.Windows.Input.StylusEventHandler 
Public Custom Event StylusEnter As StylusEventHandler 

Event Type

Implements

Remarks

StylusEnter is a routed event 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 StylusEnter tracks when the stylus enters the bounds of an element, this event more literally reports that the IsStylusOver property value has changed from false to true on this element.

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

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