As a general remark, the "Interface Tools" system in MCL allows us to
design windows and dump the code to generate it in a file. But this can be
done with most windows that appear on your screen. Load the ift, open the
backtrace window and dump its code. It's a good way to steal the code!...
This might not solve your problem directly, but I think it's often useful.
