InkCollectorTabletRemovedEventHandler Delegate
Represents the method that handles the TabletRemoved event of an InkCollector object.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in microsoft.ink.dll)
Syntax
'Declaration
Public Delegate Sub InkCollectorTabletRemovedEventHandler ( _
sender As Object, _
e As InkCollectorTabletRemovedEventArgs _
)
'Usage
Dim instance As New InkCollectorTabletRemovedEventHandler(AddressOf HandlerMethod)
public delegate void InkCollectorTabletRemovedEventHandler (
Object sender,
InkCollectorTabletRemovedEventArgs e
)
public delegate void InkCollectorTabletRemovedEventHandler (
Object^ sender,
InkCollectorTabletRemovedEventArgs^ e
)
/** @delegate */
public delegate void InkCollectorTabletRemovedEventHandler (
Object sender,
InkCollectorTabletRemovedEventArgs e
)
Not applicable.
Parameters
- sender
The source InkCollector object of this event.
- e
The InkCollectorTabletRemovedEventArgs object that contains the event data.
Remarks
When you create an InkCollectorTabletRemovedEventHandler 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.
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.
//...

{

// Add event handlers for cursor and button events.
theInkCollector.CursorButtonUp += new InkCollectorCursorButtonUpEventHandler(CursorButtonUp_Event);

theInkCollector.CursorOutOfRange += new InkCollectorCursorOutOfRangeEventHandler(CursorOutOfRange_Event);
theInkCollector.CursorInRange += new InkCollectorCursorInRangeEventHandler(CursorInRange_Event);
theInkCollector.CursorDown += new InkCollectorCursorDownEventHandler(CursorDown_Event);
theInkCollector.TabletAdded += new InkCollectorTabletAddedEventHandler(TabletAdded_Event);
theInkCollector.TabletRemoved += new InkCollectorTabletRemovedEventHandler(TabletRemoved_Event);

//...

{

}
private void CursorButtonDown_Event(object sender, InkCollectorCursorButtonDownEventArgs e)
{

private void CursorInRange_Event(object sender, InkCollectorCursorInRangeEventArgs e)

}
private void CursorDown_Event(object sender, InkCollectorCursorDownEventArgs e)
{
sbPanelCursor.Text = e.Cursor.Name + " Down";
}
private void TabletAdded_Event(object sender, InkCollectorTabletAddedEventArgs e)
{
sbPanelTablet.Text = "Tablet added: " + e.Tablet.Name;
}
private void TabletRemoved_Event(object sender, InkCollectorTabletRemovedEventArgs e)
