I've got a Class derived from QObject, with connectNotify() / disconnectNotify() methods overwritten and a Signal void textChanged(const QString&).
When I connect this Signal to a QLineEdits setText() slot, connectNotify is called. O.K:
When I disconnect the Signal (explicit disconnnect), disconnectNotify is called. O.K.

But when I just destroy ( destroyLater() ) the previously connected QLineEdit, I expected an implicit disconnect, but nothing happens, disconnectNotify is never called.
Why not ?
