DESCRIPTION

18       The QSqlDriverPlugin class provides an abstract base for custom
19       QSqlDriver plugins.
20
21       The SQL driver plugin is a simple plugin interface that makes it easy
22       to create your own SQL driver plugins that can be loaded dynamically by
23       Qt.
24
25       Writing a SQL plugin is achieved by subclassing this base class,
26       reimplementing the pure virtual functions keys() and create(), and
27       exporting the class with the Q_EXPORT_PLUGIN macro. See the SQL plugins
28       that come with Qt for example implementations (in the
29       plugins/src/sqldrivers subdirectory of the source distribution). Read
30       the plugins documentation for more information on plugins.
31
32       See also Plugins.

MEMBER FUNCTION DOCUMENTATION

QSqlDriverPlugin::QSqlDriverPlugin ()

36       Constructs a SQL driver plugin. This is invoked automatically by the
37       Q_EXPORT_PLUGIN macro.
38

QSqlDriverPlugin::~QSqlDriverPlugin ()

40       Destroys the SQL driver plugin.
41
42       You never have to call this explicitly. Qt destroys a plugin
43       automatically when it is no longer used.
44

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

46       Creates and returns a QSqlDriver object for the driver key key. The
47       driver key is usually the class name of the required driver.
48
49       See also keys().
50

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

52       Returns the list of drivers (keys) this plugin supports.
53
54       These keys are usually the class names of the custom drivers that are
55       implemented in the plugin.
56
57       See also create().
