Has Krusader a dark mode I can configure in Gnome?

Help
1

Greetings,
I use (and enjoy) Krusader on Gnome.
Gnome is set to dark mode, which Krusader does not detect.
I have no KDE to test if Krusader detects its dark mode.
Hence my question.

I changed the colors, but of course this leaves light frames:

Maybe have a look at something like https://discovery.endeavouros.com/applications/uniform-theme-and-fonts-for-qt-apps-in-gtk-environments/2021/05/

Thank you, this looks interesting, The QGnome description says it was introduced in Gnome 3.20.
Debian 11 uses Gnome 3.38, but I fail to find any trace of a QGnome packages.
I will continue to search

When I execute sudo apt info qt5-gtk-platformtheme I see it is installed.

I executed sudo apt install breeze-icon-theme because of warning about missing icons.
I switched from wayland to x11 because of other error messages

When I execute

echo XDG_SESSION_TYPE ===  $XDG_SESSION_TYPE
export QT_QPA_PLATFORMTHEME='gnome'
echo   QT_QPA_PLATFORMTHEME ===  $QT_QPA_PLATFORMTHEME
krusader

I get these warning and krusader opens with light border, as above.

XDG_SESSION_TYPE === x11
QT_QPA_PLATFORMTHEME === gnome

The solution is just to tell Qt the specific GNOME dark mode

export QT_STYLE_OVERRIDE='Adwaita-Dark'

Now Krusader looks awesome!

I used qt5ct

sudo apt install qt5ct

After setting up dark mode with qt5ct, I restarted my laptop and that was it.
