I have a QGroupBox with a couple of QRadioButtons inside of it and in certain cases I want all radio buttons to be unchecked. Seems that this is not possible when a selection has been made. Do you know of a way I could do this or should I add a hidden radiobutton and check that onen to get the desired result.

If you're using QGroupBox to group buttons, you can't use the setExclusive(false) function to uncheck the checked RadioButton. You can read about it in QRadioButton section of QT docs. So if you want to reset your buttons, you can try something like this:

QButtonGroup *buttonGroup = new QButtonGroup;
QRadioButton *radioButton1 = new QRadioButton("button1");
QRadioButton *radioButton2 = new QRadioButton("button2");
QRadioButton *radioButton3 = new QRadioButton("button3");

buttonGroup->addButton(radioButton1);
buttonGroup->addButton(radioButton2);
buttonGroup->addButton(radioButton3);

if(buttonGroup->checkedButton() != 0)
{
   // Disable the exclusive property of the Button Group
   buttonGroup->setExclusive(false);

   // Get the checked button and uncheck it
   buttonGroup->checkedButton()->setChecked(false);

   // Enable the exclusive property of the Button Group
   buttonGroup->setExclusive(true);
}

You can disable the exclusive property of the ButtonGroup to reset all the buttons associated with the ButtonGroup, then you can enable the Exclusive property so that multiple button checks won't be possible.
