This will not work, or worse, has undefined behavior. ListView does not
instantiate all of its elements - only those that are needed to fill the
visible area of the view. If you define the view's height to be the height of
its children, but the number of children needed depends upon the height of the
view, you're unlikely to get what you want. Why does it seem to work for
XmlListModel? Beats me.
I'd suggest doing something like:
ListView {
height: count * 50
}
If you don't want to scroll and you don't need e.g. the currentIndex
functionality of the ListView then I'd suggest using a Column with a Repeater.
This is more efficient than a ListView and automatically sizes to its content
size.
