Reload GTK4 and Qt color schemes

[Aqa-Ib]

Feature Description

I discovered a way to live reload GTK4 gtk.css and Qt6ct color themes at runtime. This would be a nice improvement for dms.

GTK4:

getAdwaitaScheme="$(gsettings get org.gnome.desktop.interface color-scheme)"                                                                 
if [ "$getAdwaitaScheme" = "'prefer-dark'" ]; then                                                                                           
  gsettings set org.gnome.desktop.interface color-scheme prefer-light && gsettings set org.gnome.desktop.interface color-scheme prefer-dark; 
else                                                                                                                                         
  gsettings set org.gnome.desktop.interface color-scheme prefer-dark && gsettings set org.gnome.desktop.interface color-scheme prefer-light; 
fi                                                                                                                                                                                                                                                                                                                         

Qt6ct:
touch ~/.config/qt6ct/qt6ct.conf

Cheers !

The qt6ct solution doesnt work for me, though the GTK4 one does.

[Aqa-Ib]

Qt6ct delays ~5 seconds to reload the color scheme when touching its config file.
What Qt program are you using to test this?

[bbedward]

Both audacious and dolphin, though this is with KColorScheme and the qt6ct-kde which might be why

Also, the Gtk4 code was inverted, this is the correct one:

getAdwaitaScheme="$(gsettings get org.gnome.desktop.interface color-scheme)"                                                                 
if [ "$getAdwaitaScheme" = "'prefer-dark'" ]; then                                                                                           
  gsettings set org.gnome.desktop.interface color-scheme prefer-light && gsettings set org.gnome.desktop.interface color-scheme prefer-dark; 
else                                                                                                                                         
  gsettings set org.gnome.desktop.interface color-scheme prefer-dark && gsettings set org.gnome.desktop.interface color-scheme prefer-light; 
fi                                                                                                                                           

This matters for non-adwaita programs that read that key to set their own schemes, i.e.: firefox.

I am using vanilla qt6ct at the moment.
Audacious reloads it for me. Dolphin is a special case though, it won't work without qt6ct-kde. In the past I used qt6ct-kde and it also hot reloaded for me though.
