"Show indentation guides" under Editor Options.
Indendation guides are not precisely what you describe (that's rather computerfreaker's answer), but they are what you show in that picture.
Question
i have scoured the internet and this site for an answer, but haven found one yet.
Do you know of any plugins for Code::Blocks that enable block lines(those things that go from curly brace to curly brace when indenting your code)?
Thanks in advance for your answers!
EDIT: i probably should have added a picture of what i meant: https://i.stack.imgur.com/FqhsH.jpg
