I did something similar by putting a popup menu on a window, and
leaving its Visible property false until it was needed.
When needed, I used its top and Width properties to make it visible
over the appropriate part of the ListBox or Editfield.
When the user chose the new value from the popup, (or moved the mouse
away - or whatever) the new value transferred to the cell, and the
popup once again becomes invisible.
This worked OK on the Mac (OS 10.4, RB2006v1). On the PC, I ended up
leaving the popup in a position of its own.

Charles,
I think what he had in mind was to actually have a column of
popup menu widgets in the listbox. In fact this is possible (on
MacOS X, at least), but the technique is well beyond the scope of
this list.

You are correct in what I would ideally like to have. You say that
it's possible on OS X (at this time, all client machines are
Macs), but beyond the scope of the list. Have you any pointers to
others on the web who may cover this technique? While a contextual
menu would do the job, it won't be obvious to the user that the
menu is available.
Actually, I don't know whether it has ever been done. What I would
do would be to use MacOS Appearance Manager functions to draw a
PopupMenu control into the cell, then use the MenuItem methods to
display a menu. Calling the Appearance Manager is the part that is
somewhat more advanced.
