Probably the best way to handle this is for the model to maintain a map of column affinity, specified as QMetaType::Type, to compare items. The items themselves should also have an individual type. A database application will only need column affinity, a spreadsheet app will need item affinity.

Curious, when it crashes like that, are you in the debugger?
When I use the camera in Qt on OSX, in normal run mode, it works. Only when I . use the debugger it crashes with the permission message.
Also, what are you doing to provide the application PLIST? I have not done that successfully

But if I include the undefined key, QML complains.

It's been a while and I don't have access to that code anymore, but that sounds

The Qt event loop is tied to your Activity. An Android app can have several
activities (which are UIs) and services. Android can kill your app at anytime,
you're supposed to stave your UI state inva bundle and restore it when it's
needed again, as per lifecycle events. It's annoying.

Yet again I find that apple changed how to get full screen. I had it working
for iOS 10, but 13 is different.
Does anyone know what I need to do to get my app full-screen again?
Specifically w.r.t. what it takes for a Qt app. I've tried a variety of
additions:
@interface QIOSViewController :
Maybe you should use qRgb() or qRgba(...) and let it put the bytes where it wants? also, note that there are qRed(), qBlue(), qGeen(), and qAlpha() which should take care of extracting the aproproate channel for you.
If you told me that in Qt, BGR32 (and BGRA32) is 0xAABBGGRR, I would agree.
So there's a couple ways in iOS to get the SSID. But I was hoping, since I need
to target android as well, that I can have a Qt solution that "just works"
complete with SSID change monitoring. There's two APIs: NEHotspotHelper which
requires and entitlement or CaptiveNetwork which was
