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. The style key is usually the class name of the required style. Note that the keys are case insensitive. For example: \quotefromfile snippets/qstyleplugin/main.cpp \skipto MyStylePlugin::keys \printuntil } \skipto MyStylePlugin::create \printuntil return 0 \printuntil } \sa keys()*//*! Constructs a style plugin with the given \a 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(QObject *parent) : QObject(parent){}/*! 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.*/QStylePlugin::~QStylePlugin(){}
