For example:
gint height, width; gtk_widget_style_get(widget, "separator-height", &height, "separator-width", &width, NULL);
It works like g_object_get() . There is no corresponding gtk_widget_style_set() , although you must install them via the RC file that you download with gtk_rc_parse() . Here is the documentation for the RC files.
Just to be clear, users usually don't like it when you mess with your themes.
