combo problem

Hi, I have been trying using the function gtk_widget_set_style( ) to change the base colour on a gtkcombo box but I can't seen to get it to change colour. I have used the same function on a gtkentry box and it worked fine. Here is an example of what I am trying to do:

int main (int argc, char* argv[])
{
        GtkWidget* Main_Window;
        GtkWidget* fixed;
        GtkWidget* entry;
        GtkWidget* combo;
        GtkStyle* gtkstyle_normal_style;
        GtkStyle* gtkstyle_grey_base;

        gtk_set_locale();
        gtk_init(&argc, &argv);

Main_Window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

        fixed = gtk_fixed_new();
        gtk_widget_show(fixed);
        gtk_container_add(GTK_CONTAINER(Main_Window),fixed);

        entry = gtk_entry_new();
        gtk_fixed_put(GTK_FIXED(fixed),entry,5,5);
        gtk_widget_show(entry);

        combo = gtk_combo_new();
        gtk_widget_show(combo);
        gtk_fixed_put(GTK_FIXED(fixed),combo,5,40);
        gtk_widget_show(combo);

gtk_widget_show(Main_Window);


    gtkstyle_normal_style = gtk_widget_get_default_style();
        gtkstyle_grey_base = gtk_style_copy(gtkstyle_normal_style);

//change the base colour in gtkstyle_grey_base to grey gtkstyle_grey_base->base[GTK_STATE_NORMAL] = gtkstyle_normal_style->bg[GTK_STATE_NORMAL]; gtkstyle_grey_base->base[GTK_STATE_ACTIVE] = gtkstyle_normal_style->bg[GTK_STATE_NORMAL]; gtkstyle_grey_base->base[GTK_STATE_PRELIGHT] = gtkstyle_normal_style->bg[GTK_STATE_NORMAL]; gtkstyle_grey_base->base[GTK_STATE_SELECTED] = gtkstyle_normal_style->bg[GTK_STATE_NORMAL]; gtkstyle_grey_base->base[GTK_STATE_INSENSITIVE] = gtkstyle_normal_style->bg[GTK_STATE_NORMAL];

        //works fine
        gtk_widget_set_style(entry,gtkstyle_grey_base);
        //does not seem to have any effect
        gtk_widget_set_style(combo,gtkstyle_grey_base);

        gtk_signal_connect(GTK_OBJECT(Main_Window),
                                           "delete",
                                           GTK_SIGNAL_FUNC(eventDelete),
                                           NULL);
        gtk_signal_connect(GTK_OBJECT(Main_Window),
                                           "destroy",
                                           GTK_SIGNAL_FUNC(eventDestroy),
                                           NULL);

gtk_main();

        return(0);
}

Richard.
