Writing a SQL plugin is achieved by subclassing this base class, reimplementing the pure virtual function create(), and exporting the class with the Q_PLUGIN_METADATA() macro. See the SQL plugins that come with Qt for example implementations (in the \c{plugins/src/sqldrivers} subdirectory of the source distribution). The json file containing the metadata for the plugin contains a list of keys indicating the supported sql drivers \code { "Keys": [ "mysqldriver" ] } \endcode \sa {How to Create Qt Plugins} */ /*! \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 {How to Create Qt Plugins} */ /*! Constructs a SQL driver plugin and sets the parent to \a parent. This is invoked automatically by the moc generated code that exports the plugin. */ 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() { } QT_END_NAMESPACE
