TheQAbstractExtensionManager class provides an interface for extension managers in Qt Designer.
QAbstractExtensionManager is not intended to be instantiated directly; use theQExtensionManager instead.
InQt Designer, extension are not created until they are required. For that reason, when implementing a custom extension, you must also create aQExtensionFactory, i.e a class that is able to make an instance of your extension, and register it usingQt Designer'sextension manager.
When an extension is required,Qt Designer'sextension manager will run through all its registered factories callingQExtensionFactory::createExtension() for each until the first one that is able to create the requested extension for the selected object, is found. This factory will then make an instance of the extension.
See alsoQExtensionManager andQExtensionFactory.
[virtual]QAbstractExtensionManager::~QAbstractExtensionManager()Destroys the extension manager.
[pure virtual]QObject * QAbstractExtensionManager::extension(QObject * object, constQString & iid) constReturns the extension, specified byiid, for the givenobject.
[pure virtual]void QAbstractExtensionManager::registerExtensions(QAbstractExtensionFactory * factory, constQString & iid)Register the given extensionfactory with the extension specified byiid.
[pure virtual]void QAbstractExtensionManager::unregisterExtensions(QAbstractExtensionFactory * factory, constQString & iid)Unregister the givenfactory with the extension specified byiid.
