Autocompletion for GtkAda in GNAT GPS

Question

I'm just getting started with Ada and GtkAda development using GNAT GPS (Gnat Programming Studio), and there is something that is frustrating me: autocompletion (ie: intellisense, or whatever you want to call it) only works for my code, but not for the GtkAda library. This makes things quite slow and boring, since I have to check every API call on the GtkAda documentation every time.

So my question is simple: is there a way to enable auto completion for GtkAda on GPS?

Answer 1

Ok, seems that the problem was with GNAT 2012, I updated to GNAT 2013 and autocomplete works perfectly. Thanks Simon Wright for the hint.
