I accomplish this outside of the listbox. At the top of the window I
have the various fields to enter; some are editfields and some are
popup menus. After all fields are entered, the user clicks an "Add"
pushbutton on the far right and the data appears in the listbox below.
To update data, the user clicks on a line in the listbox, and the data
from that line appears below the listbox in editfields and popup
menus. As each field is edited and the user tabs to the next field,
the database is updated and the listbox is redrawn. I also have a
"Delete" pushbutton. So the user can select a line in the listbox,
click Delete and that record is deleted from the database. The listbox
is then redrawn and the record is not there.
There are probably more elegant ways to add, change and delete
database records, while allowing users to view all records in a
listbox, but the above method works for me.
Let me know if you want me to send you a screen shot -- in case you
want to see an example.

I need to add a popup menu temporarily to a listbox cell to ensure
the user
populates the cell with a valid string value. Once the user selects
an item
from the popup menu, I would remove the popup and place the
corresponding
string in the cell as non-editable.
I suppose, I could put text in the cell telling the user to <click
here to
add item> and then bring up a separate dialog allowing the user to
select a
valid entry from a listbox, but that doesn't seem very elegant or
efficient
to me.
How have others solved this problem?
