Re: Scrollbar flickers when clock run

[Flávio Alberto Lopes Soares <flavio maqplas com br>]

Ok, it's true, my program has other modal window that has a CList too,
and your scrollbar hasn't the problem while the clock is runing,
probably this is the explanation about other problem that occurs in my
program : it has a big pixmap (with green background) that blinks in
about 400ms (usin gtk_timeout_add) swapping other pixmap with white
background, when the clock and  pixmap are runing this flicker occur
with pixmap happening an "ugly effect".

I will try something in this way.

Thanks a lot
