Dummy data models and properties for QML

When you are building a quick prototype UI in QML, or when you are isolating an issue writing a SSCCE, you can use a feature in qmlscene (or the visual Qt Quick Designer in Creator) that inserts properties in the root context from files in a directory. This saves you from having to add an example model in C++.

This repository contains some example models that you can use in your prototypes and examples. The properties will be seen in your QML document with the same name as the file in disk. All the models have names ending in Model to avoid name clashes. For example:

import QtQuick 2.0

ListView {
    width: 800; height: 600
    model: aWordsModel
    delegate: Text {
        text: word
    }
}

This is an alternative to using something like model: 42, where the view would have an even more dummy model of 42 elements without content. You could use the index to generate a string, but it would be very ugly to simulate a change in the model contents, for example.

Isn’t this still too boring?

Yes, for now at least. The idea is to add richer models with several roles that you could use to prototype complex views with heavier delegates. Also, instantiating some models at will, instead of adding all of them as context properties should be supported.

Feel free to fill issues with your wished use case.
