Заметки

The event handler receives an argument of type PenInputPanelVisibleChangedEventArgs, containing data about this event.

The VisibleChanged event is raised when:

The hover target for the PenInputPanel object appears in the user interface (UI).
The UI for the full PenInputPanel object disappears.

However, this event is not raised when the hover target expands to show the UI for the full PenInputPanel object.

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

Примеры

This Microsoft® Visual C#® example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, theInkEdit. It adds a VisibleChanged event handler, VisibleChanged_Event, to the form for the PenInputPanel. In the event handler, if the pen input panel is visible, its position is changed to screen coordinates 100, 100 by calling the MoveTo method.

[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);
        }
    }
