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().

NAME

       QGfxDriverPlugin - Abstract base for Qt/Embedded graphics driver plugins

SYNOPSIS

       #include <qgfxdriverplugin_qws.h>

   Public Members
       QGfxDriverPlugin ()
       ~QGfxDriverPlugin ()
       virtual QStringList keys () const = 0
       virtual QScreen * create ( const QString & driver, int displayId ) = 0

DESCRIPTION

       The QGfxDriverPlugin class provides an abstract base for Qt/Embedded graphics driver plugins.

       The graphics driver plugin is a simple plugin interface that makes it easy to create custom graphics drivers.

       Writing a graphics driver 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 Plugins documentation for details.

       This class is only available in Qt/Embedded.

       See also Plugins.

MEMBER FUNCTION DOCUMENTATION

QGfxDriverPlugin::QGfxDriverPlugin ()
       Constructs a graphics driver plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QGfxDriverPlugin::~QGfxDriverPlugin ()
       Destroys the graphics driver plugin.

       You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.

QScreen * QGfxDriverPlugin::create ( const QString & driver, int displayId ) [pure virtual]
       Creates a driver matching the type specified by driver, that will use display displayId.

       See also keys().

QStringList QGfxDriverPlugin::keys () const [pure virtual]
       Returns the list of graphics drivers this plugin supports.

       See also create().
