gtk label and links

[Peter Vágner <pvdeejay gmail com>]

Hello,
Recently I have noticed quite nice twitter cliend in the rapid 
development. The name of the app is corebird.
What I have noticed is that it displays tweets inside a control similar 
to list where each row consists of a few boxes and labels inside those 
boxes. Tweet text is also displayed as a label. Such label includes 
links. These can be focused somehow as pressing applications key opens 
up a popup menu where the url can be copied to the clipboard.
Now the question. Is there a way to make these labels with links more 
accessible so the links will be announced while they are focused?
I was looking into this help topic 
https://developer.gnome.org/pygtk/2.24/class-gtklabel.html and I think 
there is no way on how to interface with the links it is just possible 
to add them using the pango markup and then receive a activate-link signal.

Is this a valid use case and can you understand it?
Can I do something to make such links more accessible in the app?

Greetings

Peter
