7.16. Finding an Index by Y Coordinate

If you know a y coordinate in the listbox, you can determine the index of the nearest listbox item to it by using the nearest method:

$index = $lb->nearest(y)

The nearest method returns a number that corresponds to the index of the closest visible listbox item.
