\class WidgetDatabase widgetdatabase.h
\brief The WidgetDatabase class holds information about widgets
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.
