The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins. More...
List of all member functions.
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.
See also Plugins.
You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.
Creates and returns a QSqlDriver object for the driver key key. The driver key is usually the class name of the required driver.
See also keys().
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.
See also create().
