InkPicture.CursorOutOfRange Event

아티클
12/12/2007

Occurs when a cursor leaves the physical detection range (proximity) of the tablet context.

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

Syntax

'Declaration
Public Event CursorOutOfRange As InkCollectorCursorOutOfRangeEventHandler
'Usage
Dim instance As InkPicture
Dim handler As InkCollectorCursorOutOfRangeEventHandler

AddHandler instance.CursorOutOfRange, handler

public event InkCollectorCursorOutOfRangeEventHandler CursorOutOfRange

public:
event InkCollectorCursorOutOfRangeEventHandler^ CursorOutOfRange {
    void add (InkCollectorCursorOutOfRangeEventHandler^ value);
    void remove (InkCollectorCursorOutOfRangeEventHandler^ value);
}

/** @event */
public void add_CursorOutOfRange (InkCollectorCursorOutOfRangeEventHandler value)

/** @event */
public void remove_CursorOutOfRange (InkCollectorCursorOutOfRangeEventHandler value)

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

Not applicable.

Remarks

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

When you create an InkCollectorCursorOutOfRangeEventHandler 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. The default event interest is on.

The CursorOutOfRange event fires even when in select or erase mode, not only when in ink mode. This requires that you monitor the editing mode (which you are responsible for setting) and be aware of the mode before interpreting the event. The advantage of this requirement is greater freedom to innovate on the platform through greater awareness of platform events.

Example

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.
