InkCollector.CursorButtonUp Event

Occurs when the InkCollector detects a CursorButton object that is up.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in microsoft.ink.dll)

public event InkCollectorCursorButtonUpEventHandler CursorButtonUp
/** @event */
public void add_CursorButtonUp (InkCollectorCursorButtonUpEventHandler value)

/** @event */
public void remove_CursorButtonUp (InkCollectorCursorButtonUpEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

A button on a pen tip is up when the user completes a stroke and lifts the pen from the digitizer. A button on a barrel is up when the button is not pressed.

The event handler receives an argument of type InkCollectorCursorButtonUpEventArgs that contains data about this event.

When you create an InkCollectorCursorButtonUpEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For performance reasons, the default event interest is off but is turned on automatically if you add an event handler.

When you release the right mouse button, you actually receive two CursorButtonUp events—one for right button up and one for left button up.

This C# example uses several event handlers to display the state of the Cursor objects, CursorButton objects, and Tablet objects. The application has a status bar with three panels—sbPanelCursor, sbPanelButton, and sbPanelTablet—in which messages appear when events are received.
