SetMapping of QRadioButtons

slimhs

I have a list of 32 radio buttons,I have this program:

ui->scrollArea->setWidget(ui->scrollAreaWidgetContents);
    ui->scrollArea->verticalScrollBar()->setSingleStep(30);
    for(int i=0;i<32;i++){


                radio_name.clear();
                radio_name.append("RadioButton_");
                radio_name.append(QString::number(i+1));

                radioButtons[i]=new QRadioButton(ui->scrollAreaWidgetContents);
                radioButtons[i]->setObjectName(QString::fromUtf8(radio_name.toStdString().c_str()));
               radioButtons[i]->setProperty("DeviceIndex", i +1);
}
ui->scrollAreaWidgetContents->setGeometry(0,0,480,960);

     QList<QRadioButton *> allPButtons = this->findChildren<QRadioButton *>();

     foreach (QRadioButton *button, allPButtons)
     {
         keyboardMapper->setMapping(button, button);

         connect(button, SIGNAL(clicked(bool)), keyboardMapper, SLOT(map()));
     }

the problem is on the instruction

 keyboardMapper->setMapping(button, button);

How can I fix it??

@slimhs Instead of mapping you can use this new signal-slot connection.

connect(radioButton, &QRadioButton::clicked, [=](bool checked){
   qDebug() << button << checked; //the exact button with state 
});

You can add this in for loop where you create new RadioButtons.
Note that this requires c++11 compliant compiler.

where do you construct keyboardMapper?

also, for what you are trying to do there is QObject::sender which is bad programming but it works
