Yes and no. If you allow multiple selection, the list may contain multiple
items - in fact all selected ones. If you only allow single selection, the
list may be either empty or contain exactly one item. Thus "iteration" is
very limited here.

Not for a list with count () <= 1 ...

Be aware that selectedIndexes() has to cover different scenarios: single or
multiple selections, lists, trees, and tables, ...
