語法

'宣告
Public Property Visible As Boolean
'用途
Dim instance As PenInputPanel
Dim value As Boolean

value = instance.Visible

instance.Visible = value

public bool Visible { get; set; }

public:
property bool Visible {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_Visible()
/** @property */
public  void set_Visible(boolean value)

public function get Visible () : boolean
public function set Visible (value : boolean)

屬性值

型別：System.Boolean
如果可以看見畫筆輸入面板，則為 true，否則為 false。

備註

您只能在附加的控制項擁有焦點時，將 Visible 屬性設為 true。否則，設定這個屬性會產生錯誤。

安全性注意事項：
如果在部分信任的情況下使用，除了 PenInputPanel 所需的權限之外，這個屬性還需要 SecurityPermissionFlag.AllFlags (英文) 權限。如需詳細資訊，請參閱Security and Trust。

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。接著會附加名為 VisibleChanged_Event 的 VisibleChanged 事件處理常式。如果 Visible 屬性設為 true，則事件處理常式會將句子加入至 theInkEdit 的內容。

[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 VisibleChanged 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;

        // When the panel has become visible...
        if (theSenderPanel.Visible)
        {
            // Display a message in the attached edit control
            theSenderPanel.AttachedEditControl.Text += "The panel is visible." + Environment.NewLine;
        }
    }
}

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。接著會附加名為 VisibleChanged_Event 的 VisibleChanged 事件處理常式。如果 Visible 屬性設為 true，則事件處理常式會將句子加入至 theInkEdit 的內容。
