Hi,

For a project I need a simple concept: While a questionbox is open, I need to continue running the code.

The basic idea is this:

y=questbox('Do you want to quit the while loop?')
while y~=('Yes')
   disp('Useful code here')
end

But, ofcourse, this code will pause when the questionbox is called. Is there a way this doesn't happen but that the question could still affect the rest of the code?

Thanks in advance

But how could this work? What is the point of the question box since you would either have to predefine y, and this is the y that will be used or it will error for no variable y.

What are you trying to do?

The end result must be that as long as there is no answer given, the while loop keeps looping.

No, you cannot do this with questbox()

Is there a way I can do this in another setting? With a dialog box or something?

Create a pushbutton, say handles.stopbutton . Then at the place you have the questbox and "while" in your code, change it to

set(handles.stopbutton, 'Enable', 'on')
while true
  drawnow();
  if get(handles.stopbutton, 'Value') > 0; break; end
  disp('USeful code here');
end
set(handles.stopbutton, 'Value', 0, 'Enable', 'off');
