[Help-smalltalk] Connecting a signal handler "after" default handler [GTK]

[ZuLuuuuuu]

Hello,

Recently, I have a case where I want to prevent a GtkNotebook to switch
pages but because the default handler of GtkNotebook's "switch-page" signal
is executed after the custom signal of the user, I can't do it. I found a
solution to this problem where one can use this function:

http://developer.gnome.org/gtk/2.24/gtk-Signals.html#gtk-signal-connect-after

so that the custom handler is executed last. Is there a way to use this
function on GST?
