Question: How to know if a radio button is selected or not?

I have one GUI with 4 Radio Buttons and one Push Putton. All of them are in one Button Group.   I want, if the user didn't select any radio button, then the Push Button will do code-A, and if the user selected any of the radio buttons, then the Push Button will do code-B.   Any idea how to do that?   The code below is in my Push Button Function   if %user did not select any radio button, then do this else %do this if a user selected a radio button switch get(get(handles.uipanel4,'SelectedObject'),'Tag') case 'radiobutton5', line_type = 'imline'; case 'radiobutton6', line_type = 'impoint'; case 'radiobutton7', line_type = 'imfreehand'; case 'radiobutton8', line_type = 'impoly'; end

if (get(handles.radiobutton1,'Value') == 0 && get(handles.radiobutton2,'Value') == 0 &&  get(handles.radiobutton3,'Value') == 0 && get(handles.radiobutton4,'Value' == 0)

    %user did not select any radio button, then do this
  else
    %do this if a user selected a radio button

      switch get(get(handles.uipanel4,'SelectedObject'),'Tag')

      case 'radiobutton5',  line_type = 'imline';

      case 'radiobutton6',  line_type = 'impoint';

      case 'radiobutton7',  line_type = 'imfreehand';    

      case 'radiobutton8',  line_type = 'impoly';
  end
