Hi,

I guess this is more of a general question of how I can accomplish this. Imagine that you want to show disassembly at a given address (say 0x500) What one usually do is the get a bunch of instructions before and after that so you perhaps have a range of 0x400 - 0x600 to show the surrounding instructions. Then If the user scrolls up one will fetch more instructions (from 0x300, 0x200 and so on)

What I'm getting at is I wonder how to implement this in ImGui? I can show the range 0x400 - 0x600 of course with no problem but I would need a scrollbar that the user can drag so I can fetch more instructions either before or after the range.

I guess this is really similar to showing a big text file as well (where you don't actually read the whole file to memory but try to fetch data on the fly as needed)

For some inspiration of how this could work is to do some debugging in VS, switch to disassembly, drag the scrollbar around a bit and watch how it behaves.

Cheers!
