Styles

You can change the look of GTK programs such as Belvu using the gtkrc file. Create or edit the file called .gtkrc-2.0 in your home directory. Here are some suggestions for styles that you can modify:

# Change the default font size
gtk-font-name = "san serif 12"

style "scrollbar-style"
{
# Change the color of the scrollbars
        bg[NORMAL] = "#82cafa"
        bg[INSENSITIVE] = "#82cafa"
        bg[PRELIGHT] = "#97daff"

# Change the size of the scrollbars
        GtkRange::slider-width=12
}

class "*Scrollbar*" style "scrollbar-style"
