When some property, say x, has a binding with Listview's height and ListView height has binding with its parent height, x is not calculated as expected.
Please refer to the attached sample, you can see that delegateHeight has a binding with ListViews's height and is then used to calculate preferredHighlightBegin/End. But due to wrong calculations, some other index(other than currentIndex) is highlighted.
ListView {
id: listview
//It works with those 2 lines instead of anchors.fill: parent
// width: 640
// height: 351
anchors.fill: parent
property real heightRatio: 0.20
property int delegateHeight: heightRatio * height
....
preferredHighlightBegin: (height-delegateHeight)/2
preferredHighlightEnd: (height+delegateHeight)/2
// It works if delegateHeight is not used
//preferredHighlightBegin: (height-(height*heightRatio))/2
//preferredHighlightEnd: (height+(height*heightRatio))/2
..
}
