The IDE uses an internal representation of the component metadata stored 
in the '*.info' an '*.list' files in '/usr/share/gambas3/info'.

But as you are interested in classes already loaded, it's faster to look 
at them directly.

And to know if a class symbol comes from its parent, I look in the 
parent as I told you.

If a class is loaded, all its parent are necessarily loaded too.
