SyntaxBomb - Indie Coders

Hi guys, i'm new here so please forgive me if this has been solved before.
I am looking for a simple solution for creating a multicolumn listbox in Bmax. The ListBox gadget only lets you add texts as items, not TGadgets, which is unfortunate.I was trying for a while to use the ScrollBox with a panelgroup instead for adding my 'lines' to, but that is of course not going to work in the usual way.
So, how then? Any ideas?

It been a few years since I used this in a project, and I think I remember needing to fix a small memory leak. but it worked for me.

Thanx for the answer. I was just messing with it, unfortunately, it depends a lot on Win32, while i am on Mac OS X right now. I'll try and strip it down to the bare minimum to get something on the screen at least:
edit

Just commented out all Msg stuff and Consts that refered to win32/commctrl/user32

Of course this seems not to work, as the objects are created by sending some msg to the Listview (?) object, specific to Win32 API.So i try and hammer something else together...

Ok, started again with this ScrollPanel thingy. Alignment is not 100% and dragging the separator bars not possible. Have to add mouse sensitivity to those gadgets first, i think.
It is not Apple Style Guide, either.
