GtkFileChooserButton is just an GtkHBox object.  You need to connect to
the widget(s) in the GtkBox which receive events (ie which have a
GdkWindow object). For example amending your code for connecting to
w_fs_button to this works:

    GList* children =
        gtk_container_get_children(GTK_CONTAINER(w_fs_button));
    for (children = g_list_first(children); children; children =
         g_list_next(children)) {
            g_signal_connect(children->data, "button-press-event",
                             G_CALLBACK(cb_button_press_event), NULL);
    }

However, I suggest you are a little more discriminating and look at the
code for GtkFileChooserButton to find out which widget in particular is
receiving events and connect to that one.
