51
52 \brief The QDecorationPlugin class is an abstract base class for
53 window decoration plugins in Qt for Embedded Linux.
54
55 Note that this class is only available in \l{Qt for Embedded Linux}.
56
57 \l{Qt for Embedded Linux} provides three ready-made decoration styles: \c
58 Default, \c Styled and \c Windows. Custom decorations can be
59 implemented by subclassing the QDecoration class and creating a
60 decoration plugin.
61
62 A decoration plugin can be created by subclassing
63 QDecorationPlugin and implementing the pure virtual keys() and
64 create() functions. By exporting the derived class using the
65 Q_EXPORT_PLUGIN2() macro, the default implementation of the
66 QDecorationFactory class will automatically detect the plugin and
67 load the driver into the application at run-time. See \l{How to
68 Create Qt Plugins} for details.
69
70 To actually apply a decoration, use the
71 QApplication::qwsSetDecoration() function.
