Simple, clean theme engine... ./configure [--prefix=/where/you/want/it] make make install Then either use the Gnome Control Center to select the theme or put the following into your ~/.gtkrc : include "$prefix/share/themes/ThinIce/gtk/gtkrc" ($prefix is what you sent to told configure, or /usr/local if you said nothing) You can apply different engine styles to different widget (or widget classes). The scrollbar uses mark_type1 for the slider and mark_type2 for the buttons on the end. Handles on toolbars uses mark_type1. Valid options for the mark types are: NOTHING - nothing SLASH - single (buttons) or double (slider + handles) slashes INVSLASH - inverted slash(es) DOT - dot(s) INVDOT - inverted dot(s) The styles 'handlebox_marks', 'scrollbar_marks' and 'scroll_button_marks' are kinda deprecated.. almost.. they're just mapped to the mark_typeX styles..
