This property is read-only. This property has no default value.

Remarks

The width of the PenInputPanel object is dependent on the screen resolution for the particular Tablet PC. The default value at 96 dots per inch (dpi) is 570 pixels. The default value at 120 dpi is 712 pixels. The default value at 133 dpi is 790 pixels.

Starting with Microsoft® Windows® XP Tablet PC Edition with Windows XP Service Pack 2 (SP2), the Tablet PC Input Panel allows the user to continue entering handwriting by automatically increasing the size of the Input Panel to accomodate new handwriting. The Height and Width properties do not update to reflect the new size as the Input Panel grows. These properties return the original size of the Input Panel. They also do not report the dimensions of the Input Panel hover target.

Examples

[C#]

This C# example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, inkEdit1. It then attaches a VisibleChanged event handler, VisibleChanged_Event. In the event handler, it adds a sentence to the content of the edit control to which the PenInputPanel is attached. The sentence states the width of the pen input panel in pixels by retrieving the Width property and converting it to a string with the ToString method.

//...

// 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(inkEdit1);

    // 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 (e.NewVisibility)
        {
            // Display the width of the panel in the attached edit control
            theSenderPanel.AttachedEditControl.Text +=
                    "The width of the panel is ";
            theSenderPanel.AttachedEditControl.Text +=
                     theSenderPanel.Width.ToString();
            theSenderPanel.AttachedEditControl.Text += " pixels.\n";
        }
    }
}
