+  \class CategoryMenu
+  \brief The CategoryMenu widget aids in filtering records or files by Category.
+
+  The CategoryMenu widget provides a popup menu that will make filtering records
+  or files by category much easier.  The widget will lookup the available
+  categories for an application, populate the menu, and keep a track of which
+  categories are being filtered against.  A set of categories can be tested
+  by the isSelected() function to see if a record or file containing those
+  categories would be allowed through by the filter.
+
+  \warning Currently this class is not suitable for extending.
