NAME

       QImageFormatPlugin - Abstract base for custom image format plugins

SYNOPSIS

       #include <qimageformatplugin.h>

   Public Members
       QImageFormatPlugin ()
       ~QImageFormatPlugin ()
       virtual QStringList keys () const = 0
       virtual bool installIOHandler ( const QString & format ) = 0

DESCRIPTION

       The QImageFormatPlugin class provides an abstract base for custom image format plugins.

       The image format plugin is a simple plugin interface that makes it easy to create custom image formats that can be used transparently by
       applications.

       Writing an image format plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys() and
       installIOHandler(), and exporting the class with the Q_EXPORT_PLUGIN macro. See the Plugins documentation for details.

       See also Plugins.

MEMBER FUNCTION DOCUMENTATION

QImageFormatPlugin::QImageFormatPlugin ()
       Constructs an image format plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QImageFormatPlugin::~QImageFormatPlugin ()
       Destroys the image format plugin.

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

bool QImageFormatPlugin::installIOHandler ( const QString & format ) [pure virtual]
       Installs a QImageIO image I/O handler for the image format format.

       See also keys().

QStringList QImageFormatPlugin::keys () const [pure virtual]
       Returns the list of image formats this plugin supports.

       See also installIOHandler().

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().
