  * @class OTabWidget

  *
  * OTabWidget is a derivation of TrollTech's QTabWidget which provides
  * a stack of widgets.  Widgets can be selected using either a tab bar or
  * drop down list box.
  *
  * The normal way to use OTabWidget is to do the following in the
  * constructor:
  * - Create a OTabWidget.
  * - Create a QWidget for each of the pages in the control, insert
  *   children into it, set up geometry management for it, and use addTab()
  *   to add the widget.
