Hi Cyphre, have found that I am in need of the following and thought I
would pass along
what I have cobbled together.
1.) has-user-data? - Determine if any given face is actually an active
gadget. Should inactive gadgets
have a default behaviour that makes them
check if they are valid before they can do
anything?
2.) update-check - Updates the check box. Maybe this should be built into
my-list as a default
behaviour of the check box. Don't know enough
to make this happen.
3.) get-selected-checks - Returns all check boxes that have been defined
with a 'text field and been
checked off.
Small sample of what I mean.
