Ah that is nice, you just don't need the set messages. :)

I always looked at the iem gui objects as more sophisticated and better for GUI front ends, not meant for writing a self-documenting patch.  They save time and look/act better, but everyone I have met using pd for educational purposes uses the more simple numberbox.

I attached a modified version of your patch to show what I mean.  On the
right, you can look at the patch and figure out the behavior before you
scroll the gatom box (important if you want to make sure you're avoiding
a buffer overflow).

On the left, you have to read the source code for those GUI objects to
figure out what's going to happen.  Judging from your original patch,
I think you assumed that sending a float straight to the [nbx] would
update the value in the slider (so did I).  This turns out not to be the
case: the two GUIs are only bound together if you change the values on one
of them using the mouse.

If someone who reads and understands c better than me can explain why
the iemgui magic works as it does, I'll be happy to document it.
