🤑 [QTBUG-6781] QObject::disconnect() disconnects all connected slots - Qt Bug Tracker

australia-icon

The QObject class is the base class of all Qt objects. QObject is the heart of the Qt Object Model. The central feature in this model is a very powerful mechanism for seamless object communication called signals and slots. You can connect a signal to a slot with connect() and destroy the connection with disconnect().
Now I want a function to disconnect all the signals from receiver’s slot(). There is an option: @QObject::disconnect(receiver, SLOT(slot()));@ but this connects only the signals in the current object. I want to disconnect ALL signals, without knowing the objects that are connected to the slot. Any ideas?
The goal I want to reach is to change behavior of an object by connecting different slots to it's signal. For example: object.disconnect() // disconnect all slots object.connect(one_super_slot) object.disconnect() // disconnect all slots object.connect(another_super_slot)

Qt bindings for JRuby with (optional) extension to provide backward compatibility with Qt Ruby programs. The API is implemented using Qt Jambi, the Java version of the Qt framework. For Qt Ruby programs it provides a QtJambi inspired interface to the Signals/Slots system without the need to use C++ signatures. - CeesZ/qt_connect

Nonetheless, the components need to communicate with each other and you need some kind of callback-mechanism. And this, ladies and gentlemen, this is where Qt's signals and slots comes to the rescue. This is the third post in the series "Crash course in Qt for C++ developers" covering the signals and slots mechanism. The other topics are listed.

Qt Disconnect Slot Example - While developing with Qt, you only need to know about the absolute method index Qt disconnect all slots

Disconnect a vtk object from a qt object. Passing no arguments will disconnect all slots maintained by this object. Passing in only a vtk object will disconnect all slots from it.

Signals and Slots in Depth. The signals and slots mechanism is fundamental to Qt programming. It enables the application programmer to bind objects together without the objects knowing anything about each other.

Bonus: no, Qt doesn't support such deep introspection, you can't get list of all connected slots or something another, but in most cases, you don't need this at all. One useful info, that Qt gives you is sender(), pointer to object that sent signal. Edit. As doc said: Disconnect everything connected to an object's signals
The connection mechanism uses a vector indexed by signals. But all the slots waste space in the vector and there are usually more slots than signals in an object. So from Qt 4.6, a new internal signal index which only includes the signal index is used. While developing with Qt, you only need to know about the absolute method index.
