參數

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

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

備註

VisibleChanged 事件發生於 PenInputPanel 物件自行顯示或隱藏時。

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。它會將 VisibleChanged 事件處理常式 VisibleChanged_Event 加入至 PenInputPanel 的表單。在事件處理常式中，如果「畫筆輸入面板」為可見的，則會藉由呼叫 MoveTo 方法，將畫筆輸入面板的位置變更為螢幕座標 100, 100。

[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 PenInputPanelVisibleChanged event handler
    thePenInputPanel.VisibleChanged +=
        new PenInputPanelVisibleChangedEventHandler(VisibleChanged_Event);
}

//...

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

        // If the panel has become visible...
        if (e.NewVisibility)
        {
            // Move the pen input panel to
            // screen position 100, 100
            theSenderPanel.MoveTo(100, 100);
        }
    }
}
