Dark theme for Perforce P4V Helix on Linux?

Question

Is there a way to get a dark theme for the Perforce P4V Helix GUI on Ubuntu Linux 16.04 LTS?

Please help me understand why is this a down voted question? I'm a professional programmer asking other programmers if there is a way this could be done by coding something custom or some sort of plugin I haven't heard of. I researched it myself first and couldn't find a solution so I thought of here. — Veener, Apr 13 '18 at 23:15
I think it's a fine question and I don't know why it's downvoted. Typical stackoverflow behavior, downvote and disappear. — Br.Bill, May 22 '18 at 21:49

This one has very nice colors, but added lines are almost unreadable in diff view — Grief, Jan 22 '19 at 09:05
This worked well after moving to KDE Plasma. Before trying this, I could not read the text in P4v, esp the menus. Thanks! — pigswig, May 28 '19 at 14:51

Short answer: no.

Longer answer: since P4V is built on Qt, in theory it should be possible to apply modified "styles" to it, but I have never heard of anyone doing this successfully. IIRC there are a lot of custom UI widgets that aren't style-able.

EDIT - This theme doesn't work correctly with the latest version of P4V, I recommend mokoto's answer above!

I've modified the Default.qss inside Perforce/P4VResources/skins to create my own dark theme.

I'll Post it here, I added comments and mainly just edited hex code values. Feel free to use and modify.

P4V added a dark theme option in version 2019.2. You can activate it in the display settings (requires restart): Edit / Preferences / Display / Application / Application color scheme

There is a very slight enhancement of your dark theme:

I changed the text much lighter color (easier to read)
I set the color of disabled elements in the menu bar to darker gray so you notice them less

I did not check the entire theme, may be there are some text area where the color might not change or changes but should not

please be indulgent if you find one of those :-)
