Adaptive Comboboxes

Hello,

I've been looking for the answer to this for an embarrasingly long
time...

A combobox in a GUI displays values from a list. That list is updated
by user actions but I can't get the combobox to update to show the new
values that have been appended or changed in the list. Optimally, the
combobox selections should change everytime there is a change to the
list.

All I need is to know a general command that does this or an idea that
I can chase down on google. I've already constructed a combobox that
displays the first value of the list (list starts with one entry until
users add to it...).

Deep down I know that the answer is simple but I haven't been able to
find this in the man pages.

Thanks for any help,

Savage
