+  \class WidgetDatabase widgetdatabase.h

+
+  The WidgetDatabase holds information about widgets like toolTip(),
+  iconSet(), ... It works Id-based, so all access functions take the
+  widget id as parameter. To get the id for a widget (classname), use
+  idFromClassName().
+
+  All access functions are static.  Having multiple widgetdatabases in
+  one application doesn't make sense anyway and so you don't need more
+  than an instance of the widgetdatabase.
+
+  For creating widgets, layouts, etc. see WidgetFactory.
