MATLAB: Guide and waitfor selectionchangefcn

guide

Hi. In my GUIDE gui, I have a "RUN" push button, whose callback function runs through a block of conditional statements to check that the entered inputs are valid. For some bad inputs, I generate an error message, but for others, just a warning. (this is done by updating the string of a listbox).
What I would like to do is make visible a panel that asks if the person wishes to ignore the warnings and proceed anyways. This panel has a button group with two push buttons labeled "yes" and "no"
Is there a way at the end of the "RUN" push button callback function to do something like the following:
if ~isempty(warning_msg)
    set(handles.warning_panel,'Visible','on')
    ignore_warning = warning_buttongroup_SelectionChangeFcn
end
This checks if there are any warning messages, if yes, it makes visible the panel with the question and push button. The 3rd statemenet, however, I don't believe will work. Is there a way I can make it wait until a selectionchange is detected?

Best Answer

ignore_warning = false;
if ~isempty(warning_msg)
  set(handles.warning_panel,'Visible','on')
  waitfor(handles.warning_buttongroup, 'SelectedObject');
  if ishandle(handles.warning_buttongroup)  %ensure not deleted
    whichobject = get(handles.warning_buttongroup, 'SelectedObject');
    ignore_warning = strcmp(get(whichObject,'Tag'),'Yes'); %or the like
  end
end
