Simple(?) gtk_clist_moveto problem.

[Karol Bryd <kbryd femina com pl>]

Czesc! (Hi!)

    I've just started my gtk programming and I have one simple
question:
how should I use gtk_clist_move()? I have read tutorial twice but
I still don't know why it doesn't work. I have included a small c
source
that tries to display a window, with a clist in it, and a button.
My intention is to change current clist entry when user clicks on
the button. The current entry should be then centered in the clist
and it's background color should be blue. Can somebody tell me
what is wrong with this program? I'd be very grateful. Thanks.

PS. sorry for my English - it's awfull - I know :-)

Pozdrowienia (Regards)
