Hi bro i still just a beginner

this is the second QRadiobutton ...

QString licenceagrement::on_licenceag_clicked()
{
   
    if(ui->licenceag->isChecked()){
      ui->statuslineedit->setText("true");
    }else{
        ui->statuslineedit->setText("false");
    }
 ch = ui->statuslineedit->text();
    ch=photon;
    registeracc *regis=new registeracc();
   QObject::connect(ui->licenceag,SIGNAL(clicked()),regis,SLOT(regis->recipe()));
    return photon;
}

photon and ch are public QString variables
and this is the first QRadioButton
void registeracc::on_radioButton_clicked()

{
    licenceagrement * lic = new licenceagrement;
    lic->show();

}

and this is the globalsltop

void registeracc::recipe(){
    licenceagrement * lic = new licenceagrement;
if(lic->on_licenceag_clicked()=="true"){
    ui->radioButton->setChecked(true);
}else{
    ui->radioButton->setChecked(false); 
}
}

**i knew the code is not completed yet ... i have changed the code so many times .. i tried to pass QString values instead of boolean

The error message :
QObject::connect: No such slot registeracc::regis->recipe() in ..\1stapptestdata\licenceagrement.cpp:36
QObject::connect: (sender name: 'licenceag')
QObject::connect: (receiver name: 'registeracc')**

This is invalid connect call. Should be:

QObject::connect(ui->licenceag,SIGNAL(clicked()),regis,SLOT(recipe()));

Thank you bro now QObject connect signal and slots very good but the value didn't pass to the other window!

void registeracc::recipe(){
    licenceagrement * lic = new licenceagrement;
if(lic->on_licenceag_clicked()=="true"){
    qDebug()<<lic->on_licenceag_clicked();
    ui->radioButton->setChecked(true);
}else{
    ui->radioButton->setChecked(false);
    qDebug()<<lic->on_licenceag_clicked();
}
}

qDebug()<<lic->on_licenceag_clicked(); // = ""
i want it to get the QString value ... true or false!
is there any problem here!

@Proton-Phoenix You should pass this information to the slot registeracc::recipe() instead of tightly coupling your classes.
