I know that the general recommendation is to create a model in C++ and export it to QML, but sometimes it's more convenient to create a list of objects directly in QML:

// Product.qml
QtObject {
    property string name
    property real price
    property url photoUrl
    property color color
}

// main.qml
Item {
    property <list of Product> products
    
    TableView {
        model: products
        ...
    }
    
    Component {
        id: productComponent
        Product {}
    }
    
    onSomething: {
        products.append(productComponent.createObject(...))
    }
}

The question is, what type should the 'products' property have? I believe that all types available in QML now are not suitable.

• ListModel
  Its elements are not real objects, they can't have signals, functions and property bindings, property types are limited (string, number, bool).

• js array
  Not strongly typed (can contain anything, not only the Product).
  Does not notify a view about adding/removing elements.

• list<T>
  "Objects cannot be individually added to or removed from the list once created; to modify the contents of a list, it must be reassigned to a new list."

I propose to implement a new QML data type (or adapt list<T>), which will not have the mentioned drawbacks, it should:

• Store objects of a certain type (like list<T>).
• Has a rich method set for content manipulating (QList is a good source for inspiration).
• Works with views properly (notify about changes).
