We set that in gtk2 (icon.py) doing: width, height = gtk.icon_size_lookup(self.props.icon_size) where self.props.icon_size = 3 and the values returned are 40, 40 (in my desktop) These values are setted in: sugar-72.gtkrc: gtk-icon-sizes="gtk-menu=24,24:gtk-dnd=24,24:gtk-small-toolbar=24,24:gtk-button=24,24:gtk-large-toolbar=40,40" and sugar-100.gtkrc: gtk-icon-sizes="gtk-menu=33,33:gtk-dnd=33,33:gtk-small-toolbar=33,33:gtk-button=33,33:gtk-large-toolbar=55,55" Now if in gtk3 I do: print Gtk.icon_size_lookup(3) (True, 24, 24) I have tried adding: gtk-icon-sizes = "gtk-menu=40,40:gtk-dnd=40,40:gtk-small-toolbar=40,40:gtk-button=40,40:gtk-large-toolbar=40,40" to sugar-jhbuild/source/sugar-artwork/gtk3/theme/settings.ini doing make-install, the file is installed, icon_size_lookup continue returning 24 and the icons continue at the same size. Any idea? Gonzalo </blockquote></div>
