Detailed Description

To set this as event listener of GCF::ObjectList you need to use the method GCF::ObjectList::setEventListener(GCF::ObjectListEventListener* listener). Only one event listener can listen to GCF::ObjectList at a time.

If you want to have several listeners receive event notifications on a GCF::ObjectList list, then you can install a GCF::ObjectListEventBroadcaster on the GCF::ObjectList and register all event listeners with the broadcaster.

Member Function Documentation

GCF::ObjectListEventListener::listenerType ( ) const

virtual

Returns

the listener type. By default listener type is "GCF::ObjectListEventListener".

GCF::ObjectListEventListener::objectAdded ( int  index, QObject *  obj  )

virtual

By default there is no implementation. This function will be called when an object is added to the GCF::ObjectList.

Parameters

index	index at which the object had been added to the GCF::ObjectList.
obj	QObject pointer which was added to the GCF::ObjectList.

Reimplemented in GCF::ObjectListEventBroadcaster.

GCF::ObjectListEventListener::objectRemoved ( int  index, QObject *  obj  )

virtual

By default there is no implementation. This function will be called when an object is removed from the GCF::ObjectList.

Parameters

index	index from which the object had been removed from GCF::ObjectList.
obj	QObject pointer which was removed from the GCF::ObjectList.

Reimplemented in GCF::ObjectListEventBroadcaster.

GCF::ObjectListEventListener::objectDeleted ( int  index, QObject *  obj  )

virtual

By default there is no implementation. This function will be called when an object is deleted, which was there in the GCF::ObjectList.

Parameters

index	index at which the object pointer the existed in GCF::ObjectList.
obj	QObject pointer which was deleted.

Reimplemented in GCF::ObjectListEventBroadcaster.
