Using listcontrol

hi, i a new to wxRuby, but have been able to create a frame/listcontrol
and
fill the list with items.
What I do not understand is why the vertical scroll bar on the list does
not
respond?
I have 15 items showing and 50 in the list. Do I need some event to
activatte it?

It is hard for us to diagnose the problem, without a minimal sample of
code,
to go by. If you could, please create a minimal sample that replicates
the
problem, and send the code in your email to the list, and we will be
able to
figure out what is going on. Try not to post the original code, as it
tends
to have other stuff in there, that we don’t need to replicate the
problem.

Thanks,

Mario
