By the way, I just checked, and Creator's qmllint integration does warn about
customising native styles (in the editor itself, as annotation thingies), but
only if you explicitly import the native style:
import QtQuick.Controls.Windows
I'd imagine that less than 5% of users would actually do this, and most will
instead not specify a style and just import QtQuick.Controls. In Qt 6 the
default style is chosen based on your platform. With a good portion of users
being on Windows, the Windows style will be chosen and they will run into this
issue. qmllint relies on compile-time information, so it doesn't know about the
runtime methods of setting a style [1].
So what we might need is to add some extra logic in Creator to check which
style would be in use - if there's no qtquickcontrols2.conf, it could just
duplicate the logic in
https://code.qt.io/cgit/qt/qtdeclarative.git/tree/src/quickcontrols/qquickstyle.cpp?id=239ad232d0f1e96c1c1812c5b9839fe3062f9ddc#n167,
and somehow communicate with qmllint regarding this. Fabian, would it be
possible to somehow allow Creator to communicate with qmllint and "override"
the import checks [2]? Maybe set some environment variable that qmllint checks
first?
