Two comments:
- I created a PR so the
kde-neonextension uses QGnomeTheme on GTK based desktops. This allows for some basic GTK integration. This PR is both a stop-gap until - and preparation for when we figure out how to provide QGnomePlatform to Qt snaps. - QGnomePlatform requires GTK libraries in order to work correctly. I started a discussion to see if we can conditionally connect Qt applications to a GTK platform snap when they are running on a GTK desktop.
