What is wrong with my exit button?

I have this code on an exit button and when I hit the button and select 'yes' to save the data I receive the figure again. Why? What am i doing wrong? And why when I select 'no', I receive the questiondlg again?

    answer=questdlg('Save changes to the model?',...
            'Exit ADADCS Confirm','Yes','No','Cancel','Cancel');
             switch answer
        case 'Yes'
           [filename,pathname] = uiputfile('default','Save your GUI settings');

if pathname == 0 %if the user pressed cancelled, then we exit this callback
  return
end
%construct the path name of the save location
saveDataName = fullfile(pathname,filename); 

%saves the gui data
hgsave(saveDataName);
          delete(hObject);% Hint: delete(hObject) closes the figure
          close all;
      case 'No'
          delete(hObject);% Hint: delete(hObject) closes the figure
          close all;
  end

I tried your code and it works without any of the problems you describe, they might be caused by other code.

Just two small suggestions, the close all doesn't need the ; at the end, it's common to both Yes and No responses (also the cancel got the return line), you can remove those two "close all" lines put it after the end of that code.

Did you try to save it with the name: default ?

[Paulo Silva]

yes and worked, I only added hObject=figure to the start of the code to avoid the error with the hObject. MATLAB 2008b

I use the same code on 'Exit' menubutton and on 'x' button. The first works with problems and the second without. And I removed that you told me. The same...

[Paulo Silva]

Now I know what's the problem, when you put that code in your button the hObject is the handle of the button not the figure one, in that case delete(hObject) just deletes the button, try delete(handles.figure1) or delete(gcf)

[Paulo Silva]

Unless you are trying to close several figures you don't need the close all, just use the delete(... to delete the figure after that code.

This is the answer: delete(gcf). thank you!!!
