too narrow (1 pixel width) png image on Canvas in Box in Window

[John Mann <johnmann31416 yahoo com>]

Hello all. I'm attempting to put a Canvas into a Box
into a Window, with the Canvas holding a png image,
but the window when displayed shows just a narrow
vertical line 1 pixel wide centered left to right.
Thanks for any help. BTW, if this request for
debugging help is not appropriate for this list,
please let me know that and why...

here's the code;

#include <gtk/gtk.h>
#include <gnome.h>

GtkWidget *window;
GtkWidget *box;
GtkWidget *canvas;
GnomeCanvasGroup *group;
GnomeCanvasItem *arrow;
GdkPixbuf *arrowPixbuf;
GError **error;

void CloseTheApp(GtkWidget *window, gpointer data) {
  gtk_main_quit();
}

gint main(gint argc, gchar *argv[]) {
  gtk_init(&argc, &argv);
  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_default_size(GTK_WINDOW(window), 200,
200);
 
gtk_container_set_border_width(GTK_CONTAINER(window),
5);
  gtk_signal_connect(GTK_OBJECT(window), "destroy",
GTK_SIGNAL_FUNC(CloseTheApp), NULL);

  gtk_widget_push_visual(gdk_rgb_get_visual());
  gtk_widget_push_colormap(gdk_rgb_get_cmap());
  canvas = gnome_canvas_new();
  gtk_widget_pop_colormap();
  gtk_widget_pop_visual();
  group = gnome_canvas_root(GNOME_CANVAS(canvas));
  arrowPixbuf =
gdk_pixbuf_new_from_file("redArrow.png", error);
  arrow = gnome_canvas_item_new(group,
gnome_canvas_pixbuf_get_type(), "pixbuf", 
				arrowPixbuf, NULL);
  gdk_pixbuf_unref(arrowPixbuf);
  box = gtk_hbox_new(TRUE, 5);
  gtk_box_pack_start(GTK_BOX(box), canvas, TRUE,
FALSE, 10);
  gtk_container_add(GTK_CONTAINER(window), box);
  gtk_window_move(GTK_WINDOW(window), 500, 500);
  gtk_widget_show_all(window);
  gtk_main();
  return 0;
}
