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

       QStylePlugin - Abstract base for custom QStyle plugins

SYNOPSIS

       #include <qstyleplugin.h>

   Public Members
       QStylePlugin ()
       ~QStylePlugin ()
       virtual QStringList keys () const = 0
       virtual QStyle * create ( const QString & key ) = 0

DESCRIPTION

       The QStylePlugin class provides an abstract base for custom QStyle plugins.

       The style plugin is a simple plugin interface that makes it easy to create custom styles that can be loaded dynamically into applications
       with a QStyleFactory.

       Writing a style 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 an example.

       See also Plugins.

MEMBER FUNCTION DOCUMENTATION

QStylePlugin::QStylePlugin ()
       Constructs a style plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QStylePlugin::~QStylePlugin ()
       Destroys the style plugin.

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

QStyle * QStylePlugin::create ( const QString & key ) [pure virtual]
       Creates and returns a QStyle object for the style key key. The style key is usually the class name of the required style.

       See also keys().

QStringList QStylePlugin::keys () const [pure virtual]
       Returns the list of style keys this plugin supports.

       These keys are usually the class names of the custom styles that are implemented in the plugin.

       See also create().
