\class QDecorationFactory

\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).
