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 DOCUMENTATIONQSqlDriverPlugin::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().
