Hi forks,

I implement a dialog with radio buttons, but I don't know to get their
states (checked or not).
Could you give me an advice ?
Thank you for help,
Tri.

> send me this exaple code

The code for bitwise setting / checking can be found in the file

http://spot.colorado.edu/~romashki/idl/hc_checkbox.pro

Again, notice that in many cases, when you use

MY_CBs = CW_BRGOUP(parent, ........ /NONEXCL)

then calling WIDGET_CONTROL, MY_CBs, get_value=cb_state

places a vector of button states in the cb_state variable. I found this
to be not flexible enough, and I like the ability of 1-line IF-checking
with hc_checkbox.pro

Cheers,
Pavel
