opensnitch ui not changing to dark mode when my style is "Arch-Dark"

[freddii]

First of all it is a really usefull program :)

feature request
At the moment opensnitchs ui is not changing to dark mode when my style is "Arch-Dark".
I like it to change colors when style changes like other programs like freetuxtv or firefox do it.

setup:
GTK Theme: Arc-Dark [GTK2]
Icon Theme: Papirus-Dark

To Reproduce
In xfce:

sudo apt install arc-theme papirus-icon-theme -y

settings-manager > appearance > Style > Arc Dark
settings-manager > appearance > Icons > Papirus Dark

ok, thank you @freddii !

I'll look into it.

As far as I can tell, this is a problem of the Desktop Environment and how it handles other kind of graphical tookit different to GTK. You're running a Qt app on a GTK environment, so I guess that this problem is not particular to OpenSnitch, but all Qt apps.

On KDE works as expected when you change to a Dark style theme.

Thanks for your help.
The youtube video instruction fixed it.
In short:

sudo apt-get install -y qt5-style-plugins
sudo cat << EOF | sudo tee  /etc/environment
QT_QPA_PLATFORMTHEME=gtk2
EOF

This happens only on Gnome?

[gustavo-iniguez-goya]

nope @Ud4ba, , as far as I can tell this problem affects all GTK based Desktop Environments.
To workaround this problem it's planned to add an option to change the style: #424 (comment)
