Writing a style plugin is achieved by subclassing this base class, reimplementing the pure virtual keys() and create() functions, and exporting the class using the Q_EXPORT_PLUGIN2() macro. See \l {How to Create Qt Plugins} for details. \sa QStyleFactory, QStyle */ /*! \fn QStringList QStylePlugin::keys() const Returns the list of style keys this plugin supports. These keys are usually the class names of the custom styles that are implemented in the plugin. \sa create() */ /*! \fn QStyle *QStylePlugin::create(const QString& key) Creates and returns a QStyle object for the given style \a key. If a plugin cannot create a style, it should return 0 instead. The style key is usually the class name of the required style. Note that the keys are case insensitive. For example: \snippet doc/src/snippets/qstyleplugin/main.cpp 0 \codeline \snippet doc/src/snippets/qstyleplugin/main.cpp 1 \snippet doc/src/snippets/qstyleplugin/main.cpp 2 \sa keys() */ /*!
