InkPicture.TabletAdded Event

InkPicture.TabletAdded Event

Occurs when a Tablet is added to the system.

Definition

Visual Basic .NET Public Event TabletAdded As InkCollectorTabletAddedEventHandler
C# public event InkCollectorTabletAddedEventHandler TabletAdded;
Managed C++ public: __event InkCollectorTabletAddedEventHandler TabletAdded;

Remarks

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

When you create an InkCollectorTabletAddedEventHandler delegate, you identify the method that will handle 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.

Examples

[C#]

This C# example demonstrates using several event handlers to display the state of the cursors, cursor buttons, and tablets. This simple application has an InkPicture named theInkPicture and a status bar with three panels (sbPanelCursor, sbPanelButton, and sbPanelTablet), where simple messages appear when events are received.
