+
+ 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.
