Example

This 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);
        }
    }
}
