QString	key() const
void	setKey(const QString &key)

Signals

Detailed Description

This class can't be instantiated on its own, you must use one of the following derived classes: QObjectRegistryRef or QMultiObjectRegistryRef

If multiple objects are registered with the same key, use the derived class QMultiObjectRegistryRef. Typically this happens when delegate objects instantiated by models are registered. If you know the key is used to register only a single object, using the derived class QObjectRegistryRef is recommended.
