All Implemented Interfaces:

QAbstractFactoryInterface, QAbstractIconEngineFactoryV2Interface, QtJambiInterface

public abstract class QIconEnginePluginV2
extends QObject
implements QAbstractIconEngineFactoryV2Interface, QAbstractFactoryInterface

The QIconEnginePluginV2 class provides an abstract base for custom QIconEngineV2 plugins. Icon engine plugins produces QIconEngines for QIcons; an icon engine is used to render the icon. The keys that identifies the engines the plugin can create are suffixes of icon filenames; they are returned by keys(). The create() function receives the icon filename to return an engine for; it should return 0 if it cannot produce an engine for the file.

Writing an icon engine plugin is achieved by inheriting QIconEnginePluginV2, reimplementing keys() and create(), and adding the Q_EXPORT_PLUGIN2() macro.

You should ensure that you do not duplicate keys. Qt will query the plugins for icon engines in the order in which the plugins are found during plugin search (see the plugins overview document).
