GTK styles under KDE4 problem

I’m having a problem trying to setup QTcurve style for GTK apps,
i set and reset few times but i still get a really ugly style for all my GTK apps “firefox,gimp,devede and soh on”…
I’m doing this all by graphical mode “Configure Desk>>Appearance>>GTk Styles and fonts”…

opensuse 11 KDE4…

tks…
