Debian/MATE/i3: Always Light Mode instead of Dark Mode

[DC7IA]

Always getting light mode instead of dark mode with the current version from master.

Details: Debian 12, MATE Desktop, i3 window manager

Please tell me what else you need.

I'd also like to suggest a setting "Light Mode / Dark Mode / System Default" like so many other software does.

The problem seems to be that Qt does not notice the change of widget styles. However, there is a solution by installing a dark Qt style like kvantum-dark or any other. Then, you can pass the style via command line option to qdmr. That is

qdmr -style kvantum-dark

If you always run in dark mode, consider also setting the environment variable QT_STYLE_OVERRIDE, then you do not need to pass it to qdmr on every startup.

There is little I can do do set the theme from inside qdmr. I would need to ship my own widget theme alongside with qdmr. This will then likely not match the desktop theme. However, I've already implemented the detection of a dark theme in qdmr to fix the icons.
