[Interest] Clean way to define and categorize constants in QML

[Jérôme Godbout]

Hello Sina, this will not work (at least up to 5.5 as far as I know). Cause
QtObject doesn't have a default property to place children like Item have.
You would get the following error while parsing your script:
*Cannot assign to non-existent default property*

You can either make a simple object that have the default property for
children and property parent like Items (here's the QmlObject) or simply
use the Item {} and get the extra position,dimension properties.

class QmlObject : public QObject, public QQmlParserStatus
{
        Q_OBJECT
Q_INTERFACES(QQmlParserStatus)
        Q_CLASSINFO("DefaultProperty", "children");

Q_PROPERTY(QQmlListProperty<QObject> children READ children NOTIFY
childrenChanged STORED false);
        Q_PROPERTY(QObject* parent READ parent WRITE set_parent NOTIFY
parentChanged STORED false);

Q_PROPERTY(QString idName READ id_name NOTIFY idNameChanged STORED false);
      ...
};

Hope this help.
