NAME
QSqlDriverPlugin - Abstract base for custom QSqlDriver plugins
SYNOPSIS
#include <qsqldriverplugin.h> Public Members QSqlDriverPlugin () ~QSqlDriverPlugin () virtual QStringList keys () const = 0 virtual QSqlDriver * create ( const QString & key ) = 0
DESCRIPTION
The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins. 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.
MEMBER FUNCTION DOCUMENTATION
QSqlDriverPlugin::QSqlDriverPlugin () Constructs a SQL driver plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro. QSqlDriverPlugin::~QSqlDriverPlugin () Destroys the SQL driver plugin. You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used. QSqlDriver * QSqlDriverPlugin::create ( const QString & key ) [pure virtual] 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(). QStringList QSqlDriverPlugin::keys () const [pure virtual] 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().
