for GleShell, which is a composite widget derived from GtkWindow, i do this:

void
gle_shell_init (GleShell *shell)
{
  gtk_widget_set (GTK_WIDGET (shell),
                  "title", "GLE-Shell",
                  "type", GTK_WINDOW_TOPLEVEL,
                  "allow_shrink", TRUE,
                  "allow_grow", TRUE,
                  "auto_shrink", FALSE,
                  NULL);
}
