Qt - QCheckBox does not emit stateChanged(int state) signal

i'm having an issue with the following signal-slot

QCheckBox *hasNotify = new QCheckBox;
connect(hasNotify, SIGNAL(stateChanged(int state)), this, SLOT(showhideNotify(int state)));

I get this in my application output

QObject::connect: No such signal QCheckBox::stateChanged(int state)

But here http://qt-project.org/doc/qt-5/qcheckbox.html#stateChanged they say this signal is included in QCheckBox, so I'm confused about what the problem is.

signal and slots parameters must not contain any variable names, so you should write

connect(hasNotify, SIGNAL(stateChanged(int)), this, SLOT(showhideNotify(int)));

Take a look at documentation here
