Writing a SQL plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys() and create(), and exporting the class with the Q_EXPORT_PLUGIN2() macro. See the SQL plugins that come with Qt for example implementations (in the \c{plugins/src/sqldrivers} subdirectory of the source distribution). \sa {How to Create Qt Plugins}*//*! \fn QStringList QSqlDriverPlugin::keys() const Returns the list of drivers (keys) this plugin supports. These keys are usually the class names of the custom drivers that are implemented in the plugin. \sa create()*//*! \fn QSqlDriver *QSqlDriverPlugin::create(const QString& key) Creates and returns a QSqlDriver object for the driver called \a key. The driver key is usually the class name of the required driver. Keys are case sensitive. \sa keys()*//*! Constructs a SQL driver plugin and sets the parent to \a parent. This is invoked automatically by the Q_EXPORT_PLUGIN2() macro.*/QSqlDriverPlugin::QSqlDriverPlugin(QObject *parent) : QObject(parent){}/*! Destroys the SQL driver plugin. You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.*/QSqlDriverPlugin::~QSqlDriverPlugin(){}
