Dear folks,
I put the above message, then receive some responses. The solution in
these responses based on supposing I defined the button group by
CW_BGROUP.
In fact, IDLBuilder construct this group of buttons by the following
way:
w = widget_base(...., /NONEXCLUSIVE) ; for group of non-exclusive
buttons
b1 = widget_button(w,....)
b2 = widget_button(w,....)
I tried all the keywords of widget_info and widget_control, but cannot
retrieve the state of buttons.
Does anyone know why ?
Thanks for help.
Tri.

Tri -
When I want to keep track of something like this, I store it as
an array variable within my "state" info structure, and I keep this
variable updated in the event handler that processes events from
these buttons. Email me offline if you want details.
