[gtkada] VScale

[manuel.op.de.coul at eon-benelux.com]

I want to connect a callback handler for a GtkVScale when its
value is changed. I think I need to use the "value_changed" event
for this? However in Glade there are no VScale events, only
GtkWidget events. It warns that this signal is not in the class
ancestry if I use it anyway. Is that correct?
The GtkVScale is not in the RM yet so I need to ask.
Thanks,
