TuxGuitar doesn't pick up Win10's theme settings (dark theme)

[kainah]

It seems that on the latest snapshot as of now (2023-05-02) neither the SWT, nor the JavaFX (Qt5) versions can change the style based on Windows (10, at least) settings. So the app uses the light style instead, which looks out of place. I would expect that from SWT, but since JavaFX is tied to Qt libraries, I think it might be possible to link the styles in TuxGuitar and Win somehow. Helgar @helge17 mentioned that TuxGuitar can actually pick up *nix style settings (he uses KDE). Not a big deal, but maybe it's worth looking into, if possible.

Also, JavaFX under Win10 even looks worse than the SWT version, too much space wasted everywhere. But I think it would be manageable if TuxGuitar had any working style settings beside the icon theme. (or if there was an utility to system-wide edit the Qt5 style, but I'm not sure if there is any way to change those settings on Win)

I'm attaching both JavaFX (Qt5) and SWT versions screenshots.
