45 \class QSqlDriverPlugin
46 \brief The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins.
47
48 \ingroup plugins
49 \inmodule QtSql
50
51 The SQL driver plugin is a simple plugin interface that makes it
52 easy to create your own SQL driver plugins that can be loaded
53 dynamically by Qt.
54
55 Writing a SQL plugin is achieved by subclassing this base class,
56 reimplementing the pure virtual function create(), and
57 exporting the class with the Q_PLUGIN_METADATA() macro. See the SQL
58 plugins that come with Qt for example implementations (in the
59 \c{plugins/src/sqldrivers} subdirectory of the source
60 distribution).
61
62 The json file containing the metadata for the plugin contains a list of
63 keys indicating the supported sql drivers
64
65 \code
66 { "Keys": [ "mysqldriver" ] }
67 \endcode
