Hi all,

I'm been running into this problem several times. Say I have a modal GUI window, and if there is something wrong with its close request function, it will give an error message when I try to close it instead of closing, and I can't go back to the command window. Ctrl+C doesn't work either, so I always ends up killing matlab from task manager. Is there a way to break from a modal GUI window?

Thanks!

Niko

Hi,

one way to manage the closure of a modal figure is to encapsulate your closerequestfcn in a try-catch statement, otherwise I think you'll be forced to kill matlab.

something like :

function YourCloseRequestFcn(...)
try
   % your original code which might crash while the developpement stage
catch
   closereq; % make sure you close the window.
end
