Hi Nick,

Take a look at this page: 
http://qt-project.org/doc/qt-4.8/qdeclarativedynamicobjects.html. When 
you have tried implementing some of this, you can ask the next questions.

Dynamic object management in QML is pretty difficult, so you have some 
work cut out for you. But it is of course possible, so just keep at it. 
I know QML claims to be for "dynamic" UIs, but that's just marketing 
bullshit. QML is for static UIs with things that can move. Dynamic stuff 
like this is just not what it's designed for.

Personally, I prefer doing the dynamic instantiations in C++, but that's 
probably just all my C++ experience talking :)

I hope this helps,
