InkOverlay.TabletRemoved 事件

项目
11/04/2008

从系统移除 Tablet 对象时发生。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Event TabletRemoved As InkCollectorTabletRemovedEventHandler
用法
Dim instance As InkOverlay
Dim handler As InkCollectorTabletRemovedEventHandler

AddHandler instance.TabletRemoved, handler

public event InkCollectorTabletRemovedEventHandler TabletRemoved

public:
 event InkCollectorTabletRemovedEventHandler^ TabletRemoved {
    void add (InkCollectorTabletRemovedEventHandler^ value);
    void remove (InkCollectorTabletRemovedEventHandler^ value);
}

/** @event */
public void add_TabletRemoved (InkCollectorTabletRemovedEventHandler value)
/** @event */
public void remove_TabletRemoved (InkCollectorTabletRemovedEventHandler value)

JScript 不支持事件。

备注

事件处理程序接收 InkCollectorTabletRemovedEventArgs 类型的参数，该参数包含有关此事件的数据。

创建 InkCollectorTabletRemovedEventHandler 委托时，需要标识将处理该事件的方法。若要将该事件与事件处理程序关联，请将该委托的一个实例添加到事件中。除非移除了该委托，否则每当发生该事件时就会调用此事件处理程序。出于性能方面的原因，默认事件关注处于关闭状态，但如果添加事件处理程序，它将自动打开。

示例

如果 Tablets 集合中的每个 Tablet 对象都支持 PitchRotation 属性，则此示例中的事件处理程序将激活仅对 3D 数字化仪可用的特殊应用程序功能。

Private Sub Event_OnTabletRemoved(ByVal sender As Object, ByVal e As InkCollectorTabletRemovedEventArgs)
    Me.Is3DActive = New Tablets().IsPacketPropertySupported(PacketProperty.PitchRotation)
End Sub

private void Event_OnTabletRemoved(object sender, InkCollectorTabletRemovedEventArgs e)
{
    this.Is3DActive = new Tablets().IsPacketPropertySupported(PacketProperty.PitchRotation);   
}

启动时，InkOverlay 对象 mInkOverlay 将注册事件处理程序。

' register the TabletAdded and TabletRemoved event handlers
AddHandler mInkOverlay.TabletAdded, New InkCollectorTabletAddedEventHandler(AddressOf Event_OnTabletAdded)
AddHandler mInkOverlay.TabletRemoved, New InkCollectorTabletRemovedEventHandler(AddressOf Event_OnTabletRemoved)

// register the TabletAdded and TabletRemoved event handlers
mInkOverlay.TabletAdded += new InkCollectorTabletAddedEventHandler(Event_OnTabletAdded);
mInkOverlay.TabletRemoved += new InkCollectorTabletRemovedEventHandler(Event_OnTabletRemoved);
