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 How to Create Qt Plugins for details.

This class is only available in Qtopia Core.

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.

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.

See also create().
