You can of course define your objects like this:


Foo {
   id: foo
}


Bar {
   id: bar
}


property variant items: {
   "foo": foo,
   "bar": bar
}


Hope that helps...



 
I should state my use case as well: I'm doing a small page based embedded app (less than 20 pages), based on a StackView, where I'm thankfully not hardware constrained (it's a fast PC). So I have no reason to use Loader to load pages dynamically but was thinking of keeping them all statically in a map, so that I can switch page based on the name of the page (e.g "WelcomeScreen") by calling some function or perhaps emitting a signal with the name as argument.
