Need help regarding heading into the Okular Feature: 388450

[Dileep Sankhla]

Hello devs,

I have spent the past three days in heading into this feature request [1]
regarding scrolling the annotations along with the scrollbar and I have
been finding out how to unfix the position of the annotation window that
remains fixed to its position while scrolling the pageview.
I'm trying to get an idea from the annotations that remains glued to the
pageview and do scroll with the scrollbar and hence applying the same
approach ( and a bit of the similar code too) in order to achieve this on
the annotation window.
But now the problem is I'm confused inside the large codebase and I tried
to search for the keywords like "mouseMove", "scroll", "fixed"  but without
any success in finding the relevant section.
I also did minor tweaks and changes in order to understand the behavior but
until now, I'm nowhere.

I'm still searching but now I doubt my way of fixing a bug. Can you please
suggest me how to proceed to fix/implement the bug/feature and how to
search the code, inspect the Qt elements and all? What to do now?
I have read 'get started' guide but it doesn't emphasis on my own dilemma.
