true if the pen input panel is visible; otherwise, false.

Заметки

You can set the Visible property to true only when the attached control has focus. Otherwise, setting this property generates an error.

Примечание о безопасности.
If using under partial trust, this property requires SecurityPermissionFlag.AllFlags permission, in addition to the permissions required by PenInputPanel. See Security and Trust for more information.

Примеры

This C# example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, theInkEdit. It then attaches a VisibleChanged event handler, VisibleChanged_Event. The event handler adds a sentence to the content of theInkEdit if the Visible property is set to true.

[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;
        }
    }
