// This example shows the same model in three different ListView items,
// with different highlight ranges. 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 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.
