Detailed Description

The QDecorationPlugin class provides an abstract base for custom QDecoration plugins.

The decoration plugin is a simple plugin interface that makes it easy to create custom decorations that can be loaded dynamically into applications with a QDecorationFactory.

Writing a decoration 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.


Member Function Documentation

QDecorationPlugin::QDecorationPlugin ( QObject * parent = 0 )

Constructs a decoration plugin with parent parent. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QDecorationPlugin::~QDecorationPlugin ()

Destroys the decoration plugin.

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

QDecoration * QDecorationPlugin::create ( const QString & key )   [pure virtual]

Creates and returns a QDecoration object for the decoration key key. The decoration key is usually the class name of the required decoration.

Reimplemented from QDecorationFactoryInterface.

See also keys().

QStringList QDecorationPlugin::keys () const   [pure virtual]

Returns the list of decoration keys this plugin supports.

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

Reimplemented from QFactoryInterface.

See also create().
