I am using Sabayon with the xfce4.10 desktop.

How do I make the scrollbars on the right side of every window wider?

I have added to the file .gtk_qt_engine_rc this:
>
style "gtk-qt-dynamic-27" { GtkScrollbar::slider-width = 40 } widget_class "*" style "gtk-qt-dynamic-27"
<


and I have added to the file .gtkrc-2.0-kde4 this:
>
style "scroll"
{
* * GtkScrollbar::slider-width = 40
}
class "*" style "scroll"
<


But these do not make any change.

Also, how do I restart xfce so that I can see the changes without rebooting?

Thanks

I'm not sure that editing a kde configuration file will have any effect on xfce.
