Earlier quoted context omitted.
How is Qt within a GNOME or Xfce environment any more "native" than Qt on Windows or Mac? You have reduced the definition of "native" to merely compatible with X11/Wayland (that's the only common denominator). Well now, Tk, FLTK, Swing, and even Wine are all native.
Both Qt and GTK have facilities for integrating into each other’s desktop environments (see [1]). Sometimes they blend in nicely, sometimes they stand out a bit, but I think it works out pretty okay. [1]: https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK...
Neither Qt nor GTK are desktop environments and Qt certainly isn’t defined by a dominant desktop environment - KDE isn’t even what pays their bills.
You’re still proving my point. The common denominator here (on Linux) is just X11/Wayland. If it works out “pretty okay”, then score one for a cross platform toolkit. Still no idea what über alles “native” means.
Let’s go back to the original comment I responded to… why should I not just continue with the Qt “stupid” “hobbyhorse”
