\class QSqlDriverPlugin |
|
48 |
\brief The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins. |
|
49 |
||
50 |
\ingroup plugins |
|
51 |
\inmodule QtSql |
|
52 |
||
53 |
The SQL driver plugin is a simple plugin interface that makes it |
|
54 |
easy to create your own SQL driver plugins that can be loaded |
|
55 |
dynamically by Qt. |
|
56 |
||
57 |
Writing a SQL plugin is achieved by subclassing this base class, |
|
58 |
reimplementing the pure virtual functions keys() and create(), and |
|
59 |
exporting the class with the Q_EXPORT_PLUGIN2() macro. See the SQL |
|
60 |
plugins that come with Qt for example implementations (in the |
|
61 |
\c{plugins/src/sqldrivers} subdirectory of the source |
|
62 |
distribution). |

\fn QStringList QSqlDriverPlugin::keys() const |
|
69 |
||
70 |
Returns the list of drivers (keys) this plugin supports. |
|
71 |
||
72 |
These keys are usually the class names of the custom drivers that |
|
73 |
are implemented in the plugin. |

|
80 |
||
81 |
Creates and returns a QSqlDriver object for the driver called \a |
|
82 |
key. The driver key is usually the class name of the required |
|
83 |
driver. Keys are case sensitive. |
