Connecting in Qt 5. There are several ways to connect a signal in Qt 5. Old syntax. Qt 5 continues to support the old string-based syntax for connecting signals and slots defined in a QObject or any class that inherits from QObject (including QWidget) . connect( sender, SIGNAL( valueChanged( QString, QString ) ), receiver, SLOT( updateValue( QString ) ) ); Cod4 Private Slot Connect - If the signal is not getting The string-based SIGNAL and SLOT syntax will detect type mismatches at runtime. Having separate methods you can call in testing might be more desirable.connect in constructor? It is the COD4 MASTER SERVER !!.
