Building a single select List Box

Has anyone built a listbox ( similar to upper piccy shown )

I tried using a listView and can't get reduced height rows to dosplay ; and can't remove the first empty column.

I want something that is called like this

(call_listbox (strcat "Re-path : " xrefName)
            "Select a File name"
            (list candidateFile candidateFile candidateFile)
)

My feeble attempt is fugly.

Perhaps I should read this http://www.opendcl.com/forum/index.php?topic=2213.0;topicseen

.. or one of the 100 odd posts that refer to ListView

I'll be back tomorrow.

Is there some reason why you can't use the List Box control?

Probably 'cause I couldn't see the trees for the forest ...
It's been a while since I built new ODCL dialogs :-)

DUH !!

I've used the ListBox umpteen times before.

I'm Blind as well as silly.

Thanks Owen

I'm glad you're coming out of retirement. Metaphorically, that is.

after my nap ...
Thanks for the nudge in the correct direction Owen.

BTW:
It would be nice if the dcl-MessageBox was re-sizable.

Added : and even nicer if it could AutoSize for long display strings    ;) ;D
