/*!
  \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.
