hi,
This is really a problem. First, I would suggest looking in an
interface style guide (Motif OSF style guide if you are using motif)
becuase this will tell you or point you in the right direction of what
kind of widget you should use. However this type of widget may not
exist in IDL (I am guessing a dropdown-listbox would work very well).
It seems that a Menu is not the right thing to use here, just because of
the size, and the fact that a menu should be pretty static and change
only if the view of the application changes. How about a scrollable
list box? (can you build a scrollable base widget with buttons on it?
I don't think so, but I have seen this in OS/2) Also, using this many
buttons is kind of poor, because again you want to limit the amount of
choices (not to mention the space problem) You could be creative and
link the focus of a entry field with the displaying of a little box
window, and once the selection is made, have it fill the entry field
(but again this isn't very standard, but might serve your needs well)
I guess these are all just ideas you can throw around, hope they
help.

PS: does anyone know if you can get directly at Motif from IDL. A
little while ago, I seem to remember someone saying that they opened
a dialog box or something.. I would love to see/hear more about
this. Any any information would be helpful.
