Apologies for wating your time - as is usual, I spotted my solution
within minutes of posting the query, and sent an apology to the list.
The reason I was resizing things explicitly was because I had
misunderstood the packing options (on gtk_box_pack_start) and
found that my drawing area and sliders remained fixed in size.
After re-reading the manual, the penny dropped and I was able to
achieve what I wanted without problem.
Thanks for the tip about using a 2x2 table, I'll give it a try
sometime soon. At present I have a vbox containing 2 hboxes,
the first with drawing area and V scrollbar, the second with
the H scrollbar and a dummy label, the latter having its size
set to match the width of the V scrollbar above it. Seems to work
fine.
