Qt connect to virtual slot

Signals & SlotsQt for Python

Does it make sense to write a intermediate base abstract class (lets name it BaseConfigurationPage) with these two slots as virtual pure methods ? (Every possible configuration page will always have these two methods, so I would say "yes") Before I do the heavy change in my code (if I have to) : does Qt support virtual pure slots ? Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. Why can not I call virtual function from base class slot Qt

General and Desktop. Qt's 'connect()' and virtual slot function.It will output "derived", that is, the base class's connect option, connect the signal to the derived class's slot. connecting a QAction to a virtual slot? - qt Yes, overriding virtual slots works just with every other virtual method. In the end, the signal/ slot connect is just a method call, which can be either virtual or non- virtual.Sending Structure from TCP Client (NON QT) to TCP Server (QT) Simulate mouse click for QWebEngineView QML ParentChange...

c++ - Does Qt support virtual pure slots? - Stack Overflow Yes, just like regular c++ pure virtual methods. The code generated by MOC does call the pure virtual slots, but that's ok since the base class can't be instantiated anyway... Again, just like regular c++ pure virtual methods, the class cannot be instantiated until the methods are given an implementation. Pure virtual class with singals and slots | Qt Forum
