  1. Subclass QMenuBar, and call the new class whatever you want, e.g., FancyMenuBar.
  2. Add the Q_OBJECT macro in your class definition (google for more info) in fancymenubar.h.
  3. Add the line public slots: in your class definition, e.g., somewhere between public: and private:.
  4. Add the slot definition under that line, e.g., void fancySlot();.
  5. Implement the slot definition, e.g.,

(in fancymenubar.cpp)

void FancyMenuBar::fancySlot()
{
    // type code here
}

Now you can use the slot via the QObject::connect() function, or use the slot as if it were a normal public function.
