Here is his reply from IRC (after you left):

[01:37:57] <opDispatch> hi, only on linux.
[01:38:17] <opDispatch> it's because that depends on the widgetsets.
[01:38:30] <opDispatch> so on linux this is possible thnaks to gtk / Qt
[01:38:52] <opDispatch> but on windows this is not possible because native controls (aka WinControls) dont support theming
[01:39:11] <opDispatch> well... in the ancinet times there was uxtheme patcher ;)
[01:39:17] <opDispatch> ancient times
[01:39:20] <opDispatch> very ancient

About that dark mode on Linux... any idea how we trigger it?

I see that Dexed isn't picking up the Qt theme from my desktop settings, also dexed --help doesn't produce any command line options, and a search on "dexed dlang dark mode" only brings up this thread.

If I can get dexed setup as my standard D IDE, I'll certainly "buy a copy" (aka make a donation).  Currently it's the only program on my desktop that I've not been able to coerce into dark mode so far.

In general dexed is looking quite promising indeed.

It is because the linux build is based on gtk2 so you have to select the right gtk theme. You mention QT so I will assume that you have a Plasma DE.

This is how you can select the GTK theme :

    $ kcmshell5 kcm_style

At the bottom there's a button with a text mentioning gtk and Gnome. Click and select a dark gtk theme.

If you dont use plasma then see also https://www.reddit.com/r/linuxquestions/comments/rentij/bspwm_how_do_i_change_the_gtk_theme_from_the/

For example, this is how it looks with the Arc-Dark theme https://c.gmx.com/@558129942915716568/juXG51_iQMGiTfJgAPgBeA

To be frank nowadays it's only maintained and fixed.
