Well, I've tried but it didn't work. I didn't know why because it

sounds logic (it was one of the ways I had tried before).

Now the good news. I found the solution in my case using:

---
 g_signal_connect((gpointer)
            GTK_RANGE(
            GTK_SCROLLED_WINDOW(scrolledwindow)->vscrollbar
            ),
            "value_changed",
            G_CALLBACK(on_scrolledwindow_vscrollbar_value_changed),
            NULL);
---

and

---
static
void on_scrolledwindow_vscrollbar_value_changed(GtkRange *range,
                                                gpointer user_data)
{
        gdouble value = gtk_range_get_value(range);

	/* Now we can use value... */
}
---

Let me know if it was useful for you.
