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

Dear all,

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

Any suggestion will be appreciated.

Thank you.

The pushbutton is also in the button group?

Anyway what you can do is in the callback function of your pushbutton, write this if else statement

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
