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.

Meshoo

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
