I find that modify_bg on the treeview does nothing (although To get the alternating colors you would set the "rules-hint" property on GtkTreeView to TRUE (the default is FALSE). If you do not set this property to TRUE, the background should always be a solid color. Also note that "rules-hint" is only a hint to the theme engine; if the theme engine sets the "allow-rules" style property to FALSE (the default is TRUE) the colors will not be alternating. The application always has the final call about showing alternating colors, if the application sets rules-hint to FALSE and the theme still shows alternating colors, the theme is broken and needs to be fixed. regards, -kris. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
