Associate a button in GUI with a key

I have a GUI that executes a function that remains in the loop until "Esc" key is pressed or certain amount of time is passed. However, I want to do it using a push button in my GUI is pressed. I am sure there is a simple solution for it.

Thanks!

Can you edit that function?

No and I don't know hwo to do that.

I guess what I am trying to do is to set a flag inside a loop within the function but I don't know how to do it.

Well, if you can't edit the function, then there is no way to change the functionality and you will have to use the escape key. Only if you can edit the function is there any possibility to implement some sort of flag.

Thanks Rik! What if I can modify the function? then how should I proceed from there?

[Rik]

For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread. You should probably be able to modify the examples from that threat to suit your needs.

Otherwise, post what you have tried and I'll see what I can do to modify it.

There is one possibility that does not involve editing the function itself:

The function just might possibly have been implemented in terms of the function checking to see if a particular stop indication variable has been set, with a key press callback having been established that sets the flag.

If that just happens to be the case, then you could remove the key press callback and add in a button press callback that set the flag.

You would still need to edit something but it would not, in this limited case, be the code loop itself.
