51 * drop down list box.
52 *
53 * The normal way to use OTabWidget is to do the following in the
54 * constructor:
55 * - Create a OTabWidget.
56 * - Create a QWidget for each of the pages in the control, insert
57 * children into it, set up geometry management for it, and use addTab()
58 * to add the widget.
