Answer 1

If you want to change the background color of your radiobutton when he's selected you should use both slots and stylesheet.

I will name your button MyButton.

In your .h you will find :

  private :
        QRadioButton MyButton;
    private slots:
        void changeColorMyButton();

and in your .cpp add in the setup of your Mainwindow :

QObject::connect(MyButton,SIGNAL(clicked(bool)),this,SLOT(changeColorMyButton));

Your button is now connected to the signal clicked and when you will click on your button, the slot changeColorMyButton will be executed. You can now customize your slot.

   void Mainwindow::changeColorMyButton()
    {
        if(this.MyButton.isChecked())
        {
         this.MyButton->setStyleSheet("background-color: black");
        }
        else
        {   
         this.MyButton->setStyleSheet("background-color: yellow");
        }
    }
