The highlight ranges are set by the // preferredHighlightBegin and preferredHighlightEnd properties in ListView. // // The first ListView does not set a highlight range, so its currentItem // can move freely within the visible area. If it moves outside the // visible area, the view is automatically scrolled to keep the current // item visible. // // The second ListView sets a highlight range which attempts to keep the // current item within the the bounds of the range. However, // items will not scroll beyond the beginning or end of the view, // forcing the highlight to move outside the range at the ends. // // The third ListView sets the highlightRangeMode to StrictlyEnforceRange // and sets a range smaller than the height of an item. This // forces the current item to change when the view is flicked, // since the highlight is unable to move. // // All ListViews bind their currentIndex to the root.current property. // The first ListView sets root.current whenever its currentIndex changes // due to keyboard interaction. // Flicking the third ListView with the mouse also changes root.current.
