PenInputPanelChangedEventHandler 委派

表示處理 PenInputPanel 物件之 PanelChanged 事件的方法。

命名空間：  Microsoft.Ink
組件：  Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Delegate Sub PenInputPanelChangedEventHandler ( _
    sender As Object, _
    e As PenInputPanelChangedEventArgs _
)
'用途
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 不支援委派。

參數

• sender
  型別：System.Object
  這個事件的來源 PenInputPanel 物件。

• e
  型別：Microsoft.Ink.PenInputPanelChangedEventArgs
  包含事件資料的 PenInputPanelChangedEventArgs 物件。

備註

建立 PenInputPanel 物件時，PanelType 面板是預設面板。如果面板在「畫筆輸入面板」初次變成作用中之前，就因設定 CurrentPanel 屬性而變更，則會發生 PanelChanged 事件。

範例

這個 C# 範例會建立 PenInputPanel 物件 thePenInputPanel，並且將它附加至 InkEdit 控制項 theInkEdit。然後再將 PanelChanged 事件處理常式加入至 thePenInputPanel。PanelChanged 處理常式會將所附加 InkEdit 控制項的文字設定為包含新面板型別的句子。

[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();
    }
}

這個 Microsoft® Visual Basic® .NET 範例會建立 PenInputPanel 物件 thePenInputPanel，並且將它附加至 InkEdit 控制項 theInkEdit。然後再將 PanelChanged 事件處理常式加入至 thePenInputPanel。PanelChanged 處理常式會將所附加 InkEdit 控制項的文字設定為包含新面板型別的句子。

[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
