* @class OTabWidget
* @brief The OTabWidget class provides a stack of widgets.
*
* 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.
