Maybe you could connect to the "value_changed" signals of the scrollbars'
adjustments.

This may help from the FAQ:

4.9 How do I connect to GtkAdjustment signals?

Glade doesn't support this at present, but you can set it up manually, in a
similar way to question 3.6.

When you create the window, get a pointer to the widget containing the
adjustment, and connect to the "changed" or "value_changed" signals:

  window1 = create_window1 ();
  hscale = lookup_widget (window1, "hscale1");
  gtk_signal_connect (GTK_OBJECT (GTK_RANGE (hscale)->adjustment),
                      "changed", GTK_SIGNAL_FUNC (on_adjustment_changed),
                      NULL);
