This virtual function is called when something has been disconnected from signal in this object.
See connectNotify() for an example of how to compare signal with a specific signal.
If all signals were disconnected from this object (e.g., the signal argument to disconnect() was \nullptr), disconnectNotify() is only called once, and the signal will be an invalid QMetaMethod (QMetaMethod::isValid() returns false).
When a receiver living in another thread is destroyed, this function is called later, from this object's own thread; if that thread has no running event loop, it is not called at all. In every other case it is called right away, from the thread that is disconnecting the signal.
- Warning
- This function violates the object-oriented principle of modularity. However, it might be useful for optimizing access to expensive resources.
-
This function is called from the thread which performs the disconnection, which may be a different thread from the thread in which this object lives. This function may also be called with a QObject internal mutex locked. It is therefore not allowed to re-enter any QObject functions, including isSignalConnected(), from your reimplementation. If you lock a mutex in your reimplementation, make sure that you don't call QObject functions with that mutex held in other places or it will result in a deadlock.

Reimplemented from QObject.
