通过

PenInputPanelChangedEventHandler 委托

  • 项目

表示处理 PenInputPanel 对象的 PanelChanged 事件的方法。

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

语法

声明
Public Delegate Sub PenInputPanelChangedEventHandler ( _
    sender As Object, _
    e As PenInputPanelChangedEventArgs _
)
用法
Dim instance As New PenInputPanelChangedEventHandler(AddressOf HandlerMethod)

public delegate void PenInputPanelChangedEventHandler(
    Object sender,
    PenInputPanelChangedEventArgs e
)

public delegate void PenInputPanelChangedEventHandler(
    Object^ sender, 
    PenInputPanelChangedEventArgs^ e
)

/** @delegate */
public delegate void PenInputPanelChangedEventHandler(
    Object sender,
    PenInputPanelChangedEventArgs e
)

JScript 不支持委托。

参数

备注

创建 PenInputPanel 对象时，PanelType 面板是默认面板。如果在笔输入面板 第一次转为活动状态之前通过设置 CurrentPanel 属性更改面板，则会发生 PanelChanged 事件。

示例

此 C# 示例创建 PenInputPanel 对象 thePenInputPanel，并将它附加到 InkEdit 控件 theInkEdit。然后，示例将 PanelChanged 事件处理程序添加到 thePenInputPanel。PanelChanged 处理程序将所附加的 InkEdit 控件的文本设置为包含新面板类型的句子。

[C#]

//...

// Delcare the PenInputPanel object
PenInputPanel thePenInputPanel;

public Form1()
{
    // Required for Windows Form Designer support
    InitializeComponent();

    // Create and attach the new PenInputPanel to an InkEdit control.
    thePenInputPanel = new PenInputPanel(theInkEdit);

    // Add a PanelChanged event handler
    thePenInputPanel.PanelChanged +=
        new PenInputPanelChangedEventHandler(PanelChanged_Event);
}

//...

public void PanelChanged_Event(object sender,
 PenInputPanelChangedEventArgs e)
{
    // Make sure the object that generated
    // the event is a PenInputPanel object
    if (sender is PenInputPanel)
    {
        PenInputPanel theSenderPanel = (PenInputPanel)sender;

        theSenderPanel.AttachedEditControl.Text = "The panel has changed to ";
        theSenderPanel.AttachedEditControl.Text += e.NewPanelType.ToString();
    }
}

此 Microsoft(R) Visual Basic(R) .NET 示例创建 PenInputPanel 对象 thePenInputPanel，并将它附加到 InkEdit 控件 theInkEdit。然后，示例将 PanelChanged 事件处理程序添加到 thePenInputPanel。PanelChanged 处理程序将所附加的 InkEdit 控件的文本设置为包含新面板类型的句子。

[Visual Basic]

'...

' Declare the PenInputPanel object
Dim thePenInputPanel As PenInputPanel

Public Sub New()
    MyBase.New()

    'This call is required by the Windows Form Designer.
    InitializeComponent()

    ' Create and attach the new PenInputPanel to an InkEdit control.
    thePenInputPanel = New PenInputPanel(theInkEdit)

   ' Add a PanelChanged event handler
   AddHandler thePenInputPanel.PanelChanged, AddressOf PanelChanged_Event
End Sub 'New

'...

Public Sub PanelChanged_Event(ByVal sender As Object, ByVal e As _
                              PenInputPanelChangedEventArgs)
    ' Make sure the object that generated
    ' the event is a PenInputPanel object
    If TypeOf sender Is PenInputPanel Then
        Dim theSenderPanel As PenInputPanel = CType(sender, PenInputPanel)

        theSenderPanel.AttachedEditControl.Text = "The panel has changed to "
        theSenderPanel.AttachedEditControl.Text += e.NewPanelType.ToString
    End If
End Sub 'PanelChanged_Event
