QObject::connect(const QObject * sender , PointerToMemberFunction signal , const QObject * receiver , PointerToMemberFunction slot , Qt::ConnectionType type ) Using the Meta-Object Compiler (moc) | Qt 5.12.2 The Q_Flags() macro declares enums that are to be used as flags, i.e. OR'd together. Another macro, Q_Classinfo(), allows you to attach additional name/value pairs to the class's meta-object: GitHub - tonypilz/Signal-Slot-Notify: A lightweight header-only A lightweight header-only, single file signal slot notification library built on c++98 with no dependencies - tonypilz/Signal-Slot-Notify

Dynamic language tricks in C++, using Qt In the past, the signal/slot just sounded like yet another UI toolkit event handling scheme, with the extra handicap of being "impure C++" (based on an IDL compiler). Qt4 Tutorial for the Ruby Programming Language connect(@slider, Signal('valueChanged(int)') lcd, SLOT('display(int)') connect(@slider, Signal('valueChanged(int)') self, Signal('valueChanged(int)') Dugan Chen's Homepage This may seem crazy: why not just connect the signal on the first widget to the slot on the second widget? Well, that works fine until you actually want to do some processing on the value.
