Attach objects to text in GtkTextview

[Mathias Andre <mathias acronycal org>]

Hi,
I'm using a GtkTextView to display some text. 
Now what'd I'd like to do is to attach some extra informations to words.
For example attach a file's uri to a particular word (like a link in web
browser). I could attach a GtkTextTag to a word, but then I would need
to create one different TextTag for every word (as most words would have
different links).

Anyone got any idea how I could do this?

Thanks,
Mathias
