Remarks

The Refresh method restores the default panel. For example, if the DefaultPanel property is set to Keyboard and the CurrentPanel property is set to Handwriting, the Refresh method sets the pen input panel to Keyboard. If the DefaultPanel property is set to Default, the Refresh method does not change the pen input panel.

The Refresh method automatically positions the pen input panel relative to the control to which it is attached.

The Refresh method updates the pen input panel by using the Tablet PC Input Panel settings. For instance, you can make changes to the PenInputPanel object, then call Refresh to restore the settings to those copied from Input Panel.

The PenInputPanel object is updated automatically whenever the settings change on Input Panel.

Calling the Refresh method while the pen input panel does not have focus generates an error.

Security Note:
If using under partial trust, this method requires SecurityPermissionFlag.AllFlags permission, in addition to the permissions required by PenInputPanel. See Security and Trust for more information.

Examples

This C# example attaches a PenInputPanel object, thePenInputPanel, 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 PenInputPanel object is visible, its settings are restored to those of Input Panel by calling the Refresh 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)
        {
            // Restore the pen input panel settings
            // from the global Input Panel
            theSenderPanel.Refresh();
        }
    }
}

This Microsoft Visual Basic .NET example attaches a PenInputPanel object, thePenInputPanel, 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 PenInputPanel object is visible, its settings are restored to those of Input Panel by calling the Refresh method.
