Hi Tony,

Dne 29. 01. 19 v 19:19 Richardson, Anthony napsal(a):

Define a callback for the 'DeleteFcn' property of the current figure window (or 
a handle
returned by the figure() function):

    set(gcf, 'DeleteFcn', @(h, e) mycallback(h, e))

The callback will be run when the window is pressed.

Here is a simple (specific) example.  Enter at the command prompt:

    set(gct, 'DeleteFcn' @(h, e) disp('bye bye'))

Thanks a lot! This is what I was looking for, works great.

There was another problem - I did not call drawnow() in the infinite reading the messages. Took me a while to learn that the UI code is single-threaded and drawnow executes the queued callbacks.

Since my callbacks use a lot of pauses and take several secs each, I must either run them in a different thread (parallel?) or rewrite the code to run the callbacks code interleaved with reading the messages. I wonder if people face the same issue and how they tackle it.

Please do you have any idea how to catch the Ctrl+C command from IDE command window so that the figure can be closed automatically when forced-stopping the script in IDE?

I very much appreciate your advice and help.

Best regards,
