Description Matej Starc 2023-04-16 17:25:20 UTC 
SUMMARY
When you run examples/simpleexamples/AbstractApplicationWindow.qml it logs warning that we are assigning a object of non PageRow type to a PageRow typed property. It turns out we are assigning a StackView.view to that property. Also, we are doing the same for ColumnView.

See:
https://invent.kde.org/frameworks/kirigami/-/blob/master/examples/simpleexamples/AbstractApplicationWindow.qml
https://invent.kde.org/frameworks/kirigami/-/blob/master/src/controls/Page.qml#L242
https://invent.kde.org/frameworks/kirigami/-/blob/master/src/controls/Page.qml#L246

STEPS TO REPRODUCE
1. Navigate to examples/simpleexamples
2. Execute ``qmlscene AbstractApplicationWindow.qml``
3. Check the console log

EXPECTED RESULT
We shouldn't have errors in the log for things like these. It makes kirigami look ridiculous. On the other hand, the only way to "fix" this is to make that property a QObject.
