Last time I used Qt Quick, native looking widgets were outside of its scope. You're meant to define the styling you want for all of your widgets, and Qt will render them consistently across platforms.
Out of scope for Qt Quick, perfectly in scope for Qt Quick controls. It looks very native on all the platforms I’ve tried, likely due to their experience with Qt Widgets.
Nice, thanks for pointing this out. Qt Quick Controls weren't around, or at least weren't available on the platforms I was developing against, like 9 years ago.
