Just hope *that* is in fact the gdk colormap that this window is going to be shown with ;-)

Another approach (swiped from testgtk.c :-) is to:

  GdkPixmap *pixmap;
  GdkBitmap *mask;
  GdkColor  *background;
  char      *filename;
  GtkWindow *window;

 ...(initialize window and all that stuff)
  gtk_widget_realize (window);

This now means your window is actually onscreen (though not drawn), and you can continue with:

  pixmap = gdk_pixmap_create_from_xpm (window->window, &mask, background, filename)

Note you now have a *gdk* pixmap, you may want to get a gdk pixmap from that thusly:

  mypixmap = gtk_pixmap_new (pixmap, mask);

Also, you could use gdk_pixmap_create_from_xpm_d instead of gdk_pixmap_create_from_xpm
if you prefer to have the data in your program instead of in a file outside of it. Have a look at testgtk.c
to see how to do this.
Now just add your gtkpixmap to your widget, that to the window, and finally gtk_widget_show it all.
Enjoy,
