+ \class QDecorationFactory
+ \ingroup qws
+ \ingroup appearance
+
+ \brief The QDecorationFactory class creates window decorations in
+ Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ QDecorationFactory is used to detect and instantiate the available
+ decorations, allowing \l{Qt for Embedded Linux} to load the preferred
+ decoration into the application at runtime. The create() function
+ returns a QDecoration object representing the decoration
+ identified by a given key. The valid keys (i.e. the supported
+ decorations) can be retrieved using the keys() function.
+
+ \l{Qt for Embedded Linux} provides three built-in decorations: \c Default,
+ \c Styled and \c Windows. In addition, custom decorations can be
+ added using Qt's \l {How to Create Qt Plugins}{plugin mechanism},
+ i.e. by subclassing the QDecoration class and creating a mouse
+ driver plugin (QDecorationPlugin).
+
