| 45 | \class QSqlDriverPlugin |
| 46 | \brief The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins. |
| 47 | |
| 48 | \ingroup plugins |
| 49 | \inmodule QtSql |
| 50 | |
| 51 | The SQL driver plugin is a simple plugin interface that makes it |
| 52 | easy to create your own SQL driver plugins that can be loaded |
| 53 | dynamically by Qt. |
| 54 | |
| 55 | Writing a SQL plugin is achieved by subclassing this base class, |
| 56 | reimplementing the pure virtual function create(), and |
| 57 | exporting the class with the Q_PLUGIN_METADATA() macro. See the SQL |
| 58 | plugins that come with Qt for example implementations (in the |
| 59 | \c{plugins/src/sqldrivers} subdirectory of the source |
| 60 | distribution). |
| 61 | |
| 62 | The json file containing the metadata for the plugin contains a list of |
| 63 | keys indicating the supported sql drivers |
| 64 | |
| 65 | \code |
| 66 | { "Keys": [ "mysqldriver" ] } |
| 67 | \endcode |

| 77 | driver. Keys are case sensitive. |
