Custom View in QML

Hi,
i have a data model that contains properties for the screen position (x and y) of each element. Being quite new to qml, I think the way to go would be to write a custom 2d-View for that and bind the position for each element with a delegate.

I'd love to have the "model:" and "delegate:" possibilities that for example a ListModel offers.

Is there any tutorial on how to write (such a / any) custom view component?
Or ist this the wrong approach?

I think it is enough to use a Repeater element.
