Thankyou, this worked. I just needed to set the column to one that made some
sense in the context. The functionality is very limited so I turned it off
to reduce confusion.

The combo box issue remains. Here's the situation. I have set up a treeview
with a couple of columns displaying cellrenderercombos. With editing enabled
on these boxes and specific models applied to the comboboxes they show
strings based on integers in the underlying table. When I click on the box
the down arrow appears ready for mouse or text entry. I need to take action
based on characters entered, ie implement a filter on the model on which the
combobox is based. But I cannot at the moment trap the key press events once
in editing mode in the combobox.

This is not the Glib Connect before issue. I can set a keypresseventhandler
on the top window and tests show that key presses are reported right up
until the combobox goes into editing mode. This happens with or without glib
connectbefore.
