\class QSqlDriverPlugin

\brief The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins.

\ingroup plugins

\inmodule QtSql

The SQL driver plugin is a simple plugin interface that makes it

easy to create your own SQL driver plugins that can be loaded

dynamically by Qt.

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.

: QObject(parent)

Executed by:

tst_QSqlDriver
tst_QSqlQuery
tst_QSqlQueryModel
tst_QSqlRelationalTableModel
tst_QSqlThread

/*!

Destroys the SQL driver plugin.

You never have to call this explicitly. Qt destroys a plugin

automatically when it is no longer used.
