See the SQL plugins that come with Qt for example implementations (in the \fCplugins/src/sqldrivers\fR subdirectory of the source distribution). Read the plugins documentation for more information on plugins. +.PP +See also Plugins. +.SH MEMBER FUNCTION DOCUMENTATION +.SH "QSqlDriverPlugin::QSqlDriverPlugin ()" +Constructs a SQL driver plugin. This is invoked automatically by the \fCQ_EXPORT_PLUGIN\fR macro. +.SH "QSqlDriverPlugin::~QSqlDriverPlugin ()" +Destroys the SQL driver plugin. +.PP +You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used. +.SH "QSqlDriver * QSqlDriverPlugin::create ( const QString & key )\fC [pure virtual]\fR" +Creates and returns a QSqlDriver object for the driver key \fIkey\fR. The driver key is usually the class name of the retquired driver. +.PP +See also keys(). +.SH "QStringList QSqlDriverPlugin::keys () const\fC [pure virtual]\fR" +Returns the list of drivers (keys) this plugin supports. +.PP +These keys are usually the class names of the custom drivers that are implemented in the plugin. +.PP +See also create(). + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/qsqldriverplugin.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
