Detailed Description

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

+ +

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 functions keys() and create(), and +exporting the class with the Q_EXPORT_PLUGIN macro. See the SQL +plugins that come with Qt for example implementations (in the +plugins/src/sqldrivers subdirectory of the source +distribution). Read the plugins + documentation for more information on plugins. +

Member Function Documentation

QSqlDriverPlugin::QSqlDriverPlugin () +

+Constructs a SQL driver plugin. This is invoked automatically by +the Q_EXPORT_PLUGIN macro. + +

QSqlDriverPlugin::~QSqlDriverPlugin () +

+Destroys the SQL driver plugin. +

You never have to call this explicitly. Qt destroys a plugin +automatically when it is no longer used. + +

QSqlDriver * QSqlDriverPlugin::create ( const QString & key ) `[pure virtual]` +

+ +

Creates and returns a QSqlDriver object for the driver key key. +The driver key is usually the class name of the required driver. +

QStringList QSqlDriverPlugin::keys () const `[pure virtual]` +

+ +

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. +
