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.
