Nor will there be in a GUI-Builder program, unfortunately.

You are going to have to figure out a way to put an "info" or
"state" structure inside your widget program, which will contain
all the information you need to run your program (such as the
identifier of the checkbox button). The GUI Builder (AFAIK) never
imagined you would need such a thing, although I've never written
a widget program yet that didn't need it.

I'd ditch the GUI Builder (since it is not supported anymore
anyway) and get yourself a good book on widget programming.
You might look on my web page for one, if you are interested. :-)

Cheers,

David
