I compiled your code, tried it and it works as expected. What exactly
is your problem?

As a reference, I am including a cleaned up and slightly changed
version of your test code here:


#include <gtk/gtk.h>
#include <gdk/gdkdirectfb.h>

static gboolean opacity_high = FALSE;

static void
opacity_toggle (GtkWidget *widget,
                gpointer   data)
{
  GtkWidget *window = GTK_WIDGET (data);

  opacity_high = !opacity_high;

  gdk_directfb_window_set_opacity (window->window, opacity_high ? 120 : 20);
}

int
main (int argc, char *argv[])
{
  GtkWidget *window;
  GtkWidget *button;

  gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title (GTK_WINDOW (window), "Opacity Window");

  gtk_container_set_border_width (GTK_CONTAINER (window), 100);
  button = gtk_button_new_with_mnemonic ("_Yes");
  gtk_container_add (GTK_CONTAINER (window), button);
  gtk_widget_show (button);

  gtk_widget_realize (window);
  opacity_toggle (window, window);
  gtk_widget_show (window);

  g_signal_connect (button, "clicked",
                    G_CALLBACK (opacity_toggle),
                    window);

  g_signal_connect (window, "destroy",
                    G_CALLBACK (gtk_main_quit),
                    NULL);

  gtk_main ();

  return 0;
}
