I missed to tell this (not unimportant) in my E-Mail. :-) Now I repeated the test in real windows and it works. But it's interesting that it doesn't work with wine. Look here: http://img525.imageshack.us/img525/3493/gtkdemowinegc7.jpg and on the terminal: (gtk-demo.exe:8): Pango-WARNING **: couldn't load font "Sans Not-Rotated 10", falling back to "Sans Not-Rotated 10", expect ugly output.

Re: Question in using gdk_pixbuf_get_from_drawable()
Are you really sure you're accessing the GdkWindow and not the GtkWindow ?
GtkWindow *toplevel = gtk_window_new(GTK_WINDOW_TOPLEVEL);
[add some graphical stuff in that GtkWindow]
/* and then, later on... */
GdkWindow *window = toplevel->window;
if (window != NULL)
{
int x, y, width, height, depth;
GdkPixbuf *pb;
gdk_window_get_geometry (window, &x, &y, &width, &height, &depth);
pb = gdk_pixbuf_get_from_drawable(NULL,
GDK_DRAWABLE (window),
NULL, 0, 0, 0, 0, width, height);
gdk_pixbuf_save(pb, filename, "png", NULL,
"compression", "9",
NULL);
}

You cannot get rid of a top level window using g_object_unref() because
a reference is owned by GTK+. It is not that it is "not enough", it is
that it is generally not the way to do it - you cannot generally get rid
of a widget that way, because other containers may own references. It
is only really for use where you have yourself called g_object_ref() or
g_object_ref_sink() on it for your own purposes.
There is an explanation of this at:
http://library.gnome.org/devel/gtk/stable/GtkObject.html
If you want some light-weight lifetime wrappers for using GTK+ in a
program written in C++, this might give you some ideas, but gtkmm is
also a good choice:
