You have to do a gtk_widget_realize (container) before
you can use it tp create your GdkPixmap. Before you do that,
there's no X window or colormap associated with the widget - 
this results in the warning above.

Have a look at /foo/gtk+/gtk/testgtk.c for an additional
example of using pixmaps in widgets.
