Ow, I didn't realize this. If you Google for basic qml types, you always
get this:
http://qt-project.org/doc/qt-4.8/qdeclarativebasictypes.html
But this is for Qt4.8 (QtQuick 1.0)

And if you dig deeper, you find:
http://qt-project.org/doc/qt-5.0/qtqml/qtqml-typesystem-basictypes.html
Which is indeed a lot different.

About the variant, the link is here:
http://qt-project.org/doc/qt-4.8/qml-variant.html

I confused it with the 'list' property. This one you need to reassign every
time you change it.

It seems I need to drop a couple of list and variant properties in my apps
