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.PenInputPanelInputFailedEventArgs
  包含事件資料的 PenInputPanelInputFailedEventArgs 物件。

備註

若輸入焦點在使用者輸入插入附加的控制項之前就已變更，則會發生 InputFailed 事件。例如，使用者將「筆墨」輸入書寫板，然後在辨識器尚未完成之前點選另一個編輯控制項，便會引發這個事件。

透過使用傳入這個事件的視窗控制代碼，您就可以選擇在這個事件發生時自行插入文字。

範例

這個 C# 範例會建立兩個 PenInputPanel 物件 (thePenInputPanel1 和 thePenInputPanel2)，並且將它們附加至 TextBox (英文) 控制項 (textBox1 和 textBox2)。然後再將 InputFailed 事件處理常式 (InputFailed_Event) 加入至每個 PenInputPanel。在事件處理常式中，如果焦點已變更，則會藉由設定 Text (英文) 屬性，在前一個 TextBox (英文) 控制項中設定文字。

[C#]

//...

// Declare PenInputPanel objects
PenInputPanel thePenInputPanel1;
PenInputPanel thePenInputPanel2;

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

    // Create, and attach new PenInputPanels to a TextBox controls.
    thePenInputPanel1 = new PenInputPanel(textBox1);
    thePenInputPanel2 = new PenInputPanel(textBox2);

    // Add an InputFailed event handler to each PenInputPanel
    thePenInputPanel1.InputFailed +=
        new PenInputPanelInputFailedEventHandler(InputFailed_Event);

    thePenInputPanel2.InputFailed +=
        new PenInputPanelInputFailedEventHandler(InputFailed_Event);
}

//...

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

        // Set the text in the previous control
        theSenderPanel.AttachedEditControl.Text += e.Text;
    }
}
