First one warning: I'm new to C++, and i'm new to Code::Blocks, but:
there's one thing that looks really weird to me: when i want code-completion to pop up, i have to press Ctrl+Space, and i've read somewhere in here something about the automatic one... okay, i could survive that, but: when i want to access sub-class/variable/function, no completion pop-ups for that at all!
not after ".", nor "::", nor "->"! and not even after hitting Ctrl+Space again...
...isn't that strange?
my Code Completion settings:
Parser tab: everything checked
Code Completion tab: everything UNchecked, delay set to 1, but i think that doesn't matter
Cache tab: everything checked
