Fix the width of the current popup hover window when I'm scrolling

[extr15]

Description

Hi, thanks for your work to dev such a great tool!
When I use a hover window to check an array variable and expand its internal value of each element, the hover window's width will change automatically according to the current displayed content's width. It's OK but I found it was hard to use since the hover window's width (and position sometimes) was changing as I scrolled by mouse.

E.g. (sorry I cannot make screenshot now...)

import numpy as np 
a = np.random.rand(20, 3)

and the hover window of 'a' is

A1  - [0:20] : [array([0.21187257, 0.05174158, 0.93341818]), array([0.6754168 , 0.4])]   A2
B1  + 00: array([0.21187257, 0.05174158, 0.93341818])  B2                                B3
....

the first row's width is 'A1-A2'，when I scoll down until the first row is out of displayed range, the hover window's width will be 'B1-B2'. It's unconvenient if my mouse is in 'B2-B3' since now my mouse is not on hover window but on the vim's buf window! I have to move mouse to 'B1-B2' in order to focus on the hover window.

Yeah the challenge is picking a reasonable size. It is a little jarring that the popup keeps changing size, but also tricky to come up with better heuristics without writing loads of fiddly code.

Maybe we can set some options for this. I'd probably review a PR that added fixed size options for the hover popup.

Thanks for the reply.
Maybe we can fix to the max width of each row? Or in most case just the first width is enough?
Can we use some shortcut key to switch between fix and auto width?(I don't know if hover popup supports this or not)

Fixing the width of the popup is just an option (in vim; no idea about othervim). Calculating a sensible value based on current cursor position, window size etc etc. is tricky.

The code for YCM's signature help I wrote is kind of gnarly. https://github.com/ycm-core/YouCompleteMe/blob/master/python/ycm/signature_help.py#L108
