InkCollectorTabletAddedEventHandler Delegate
Assembly: Microsoft.Ink (in microsoft.ink.dll)
'Declaration Public Delegate Sub InkCollectorTabletAddedEventHandler ( _ sender As Object, _ e As InkCollectorTabletAddedEventArgs _ ) 'Usage Dim instance As New InkCollectorTabletAddedEventHandler(AddressOf HandlerMethod)
/** @delegate */ public delegate void InkCollectorTabletAddedEventHandler ( Object sender, InkCollectorTabletAddedEventArgs e )
Not applicable.
Parameters
- sender
The source InkCollector object of this event.
- e
The InkCollectorTabletAddedEventArgs object that contains the event data.
When you create an InkCollectorTabletAddedEventHandler 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 in managed code if you add an event handler.
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.
