Hi all
After creating an exclusive CW button group and sensitising it and
selecting a button, is there any way (after desensitising and sensitising
it again) to create the original configuration of no buttons selected?
Thanks for any help received.
David

David -
When you create the CW button group, use the IDS= keyword to store
the list of button ids for the group as LONARR[]. Then later you can
restore these buttons to whatever state you like, eg.
for i=0, n_elements(bgroup_ids) - 1 do $
widget_control, bgroup_ids[i], set_button=0
