[Development] Confused about HiDPI scaling and fonts

I'm trying to enable QT_ENABLE_HIGHDPI_SCALING=1 in a windows application.
It seems to work good in a multi-screen application even with different DPI
settings, but it only resizes the widgets.
The fonts always remain the same size (100% scaling).
Is there a way to use QT_ENABLE_HIGHDPI_SCALING and automatic font resize?
If I have to do manually, how to detect screen changes?
If I use QT_SCALE_FACTOR it resizes correctly both the widgets and fonts,
but once the application is started it cannot be changed anymore.
I use something like:
QApplication a(argc, argv);
thanks for any hint!
