title: Is there a way to have all radion buttons be unchecked
body: <p>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.</p>
