Detailed DescriptionThe QStylePlugin class provides an abstract base for custom QStyle plugins. QStylePlugin is a simple plugin interface that makes it easy to create custom styles that can be loaded dynamically into applications using the QStyleFactory class. 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 How to Create Qt Plugins for details. See also QStyleFactory and QStyle. Member Function DocumentationQStylePlugin::QStylePlugin ( QObject * parent = 0 )Constructs a style plugin with the given parent. Note that this constructor is invoked automatically by the Q_EXPORT_PLUGIN2() macro, so there is no need for calling it explicitly. QStylePlugin::~QStylePlugin ()Destroys the style plugin. Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly. QStyle * QStylePlugin::create ( const QString & key ) [pure virtual]Creates and returns a QStyle object for the given style 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: QStringList MyStylePlugin::keys() const { return QStringList() << "Rocket" << "StarBuster"; } QStyle *MyStylePlugin::create(const QString &key) { QString lcKey = key; if (lcKey == "rocket") { return new RocketStyle; } else if (lcKey == "starbuster") { return new StarBusterStyle; } return 0; } See also keys(). QStringList QStylePlugin::keys () const [pure virtual]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. See also create(). X
