How do I remove the focus border?

[Martin Wulffeld <tranquil mail dk>]

Hi

I'm trying to remove the focus border but only for one widget (button_2
in the example below). However, the new_style is applied to both
buttons. How come?

==BEGIN==
#include <gtk/gtk.h>

void
_gtk_style_invisible_focus(GtkStyle *style, GdkWindow *window,
GdkRectangle *area, GtkWidget *widget, gchar *detail, gint x, gint y,
gint width, gint height)
{
    ;
}

int
main(int argc, char *argv[])
{
    GtkWidget * window;
    GtkWidget * button_1;
    GtkWidget * button_2;
    GtkWidget * vbox;
    GtkStyle * old_style;
    GtkStyle * new_style;
    
    gtk_init(&argc, &argv);
    
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    
    gtk_window_set_title(GTK_WINDOW(window), "NoFocus");
    
    gtk_signal_connect(GTK_OBJECT(window), "destroy",
GTK_SIGNAL_FUNC(gtk_exit), NULL);
    gtk_signal_connect(GTK_OBJECT(window), "delete_event",
GTK_SIGNAL_FUNC(gtk_exit), NULL);
    
    gtk_container_set_border_width(GTK_CONTAINER(window), 10);
    gtk_widget_realize(window);
    
    vbox = gtk_vbox_new(0,20);
    gtk_container_add(GTK_CONTAINER(window), vbox);
    
    button_1 = gtk_button_new_with_label("Button 1");
    gtk_box_pack_start(GTK_BOX(vbox), button_1, TRUE, TRUE, 0);
    gtk_widget_realize(button_1);

    
    old_style = gtk_widget_get_style(window);
    
    
    gtk_widget_push_style(old_style);
    

    new_style = gtk_style_copy(old_style);
    new_style->klass->draw_focus = _gtk_style_invisible_focus;

    button_2 = gtk_button_new_with_label("Button 2");
    gtk_box_pack_start(GTK_BOX(vbox), button_2, TRUE, TRUE, 0);
    gtk_widget_set_style(button_2,new_style);


    gtk_widget_pop_style();
    
    
    gtk_widget_show_all(window);
    
    gtk_main();
  
    return(0);
}
==END==
