Indentation guidelines in a QPlainTextEdit

[Fuchsiaff]

So, I'm in the process of writing my own IDE and I've came across this problem:
How do I draw indentation guidelines on my QPlainTextEdit like PyCharm does it here:

I'm looking for a clue on where to start, any help would be appreciated! (I'm writing this IDE using PyQt5, not Qt5)

That's just the margins, I need to somehow draw those lines on that editor without making the editor unusable

Hi,

You might want to take a look at KDE's KTextEditor which provides the features you are looking to implement.
