Thanks !

In case anyone else has this problem, adding this to the RowLayout does the trick: Rectangle { height: rowLayout.childrenRect.height } The Rectangle by default has 0 width, and the RowLayout's childrenRect.height property has the value we're after, i.e. the maximum height of its children, visible or not. Bit of a hack, obviously.

You can change the status bar "style" via the UIApplication. setStatusBarStyle() function. UIApplication Class Reference Example Code: https://github.com/benlau/quickios/blob/master/qisystemutils.mm#L305
