I have crated a gtkstacked widget so I can have different layer on it. 

/* Creates a new button with the label "Hello World". */
    button[0] = gtk_button_new ();
    button[1] = gtk_button_new_with_label ("Goodby World");

    gtk_button_set_image(GTK_BUTTON(button[0]),
                         gtk_image_new_from_file("close.png"));

    gtk_stacked_put(GTK_STACKED(stacked), button[0]);
    gtk_stacked_put(GTK_STACKED(stacked), button[1]);

This is an example in how use it. Now the problem is how do trasparency on it and on each level.

Do you have any idea?
