Thats an interesting idea, I'm sure a simple program could be used
to parse signals in a glade file and ensure the availability of the
said callbacks in the binary - this kind of tool could be used in
makefiles to validate a built program, maybe we could take something
like this to intltool ? (you could bring this up on glade-devel ximian com
if you want... there's propably a gnome intltools list too...)

Some things are the way they are - and wont improve untill someone
who cares about those particular things sends a patch, I'm sure
James Henstrige wouldnt refuse that simple kind of patch...

Ugh - I give up here, I dont see why you are arguing that an
application distributor should support a situation where the
user tampered with the software (yes, the xml glade file that you
distributed with the app is "part of the software") - this is
not political at all.

Do people go encoding images into thier executable binaries for
fear that a user might swap the distributed jpeg with something
demeaning ?

You can look at the libgnomeui plugin included in the Glade 3 tarball.

You said you had a hard time finding the docs - I was asking where
I should put the link.
