DialogCellEditor
The default implementation of this framework method creates a label widget, using the same font and background color as the parent control.
Subclasses may reimplement. If you reimplement this method, you
should also reimplement updateContents
.

Subclasses may reimplement. If you reimplement this method, you
should also reimplement createContents
.
