[Qt-qml] Adjusting Flickable contentHeight to variable children ListViews

[jens.bache-wiig at nokia.com]

Unless you put those ListViews in a Column (or anchor them) and explicitly set their height (bind each view's height to its own contentHeight), the childrenRect will not make sense. They are all stacked on top of each other right now. Also, I suspect you should set the interactive flag to false on the ListViews so they don't interfere with top-level Flickable. For the fixed height views, you could alternatively have used repeaters instead of ListViews.

Regards,

Jens
