Dark theme in flacon

[Damians0]

Hello, I can't find an option to apply the dark theme in flacon, is it possible to do it?

The program has no options for switching the theme. The program uses the standard theme of your work environment.

On mac OS, this changes through system settings.
On Linux, it depends on the distribution and desktop environment you are using.

It's strange because in my Linux distribution (MX Linux XFCE) the dark theme is applied and it works on all apps, only in Flacon it doesn't work.

Which version are you using AppImage or from the package?

11.3.0 flatpak

Flacon is a Qt-based program, XFCE is based on GTK. Integrating the look and feel of Qt programs into GTK DE is quite messy, and doesn't always work. Especially for flatpack and AppIamge programs.

Right now I only have Solus Budgie on hand. I did a little test. The program built from source apply the theme, AppImage program does not do this.

This issue requires more in-depth research. Unfortunately now I don't have a hardware at hand, on which I can play with different Linux distributions. I will try to dig this question in the second half of May.

If you know flatpak Qt programs that apply the theme correctly, email me. I'd love to see how the programmers did it.
