*
* This is a container widget which at all times has only one item
* visible. The widget accomplishes this using setHidden(bool) on the
* children.
*
* Using currentIndex() and setCurrentIndex(int index) you can
* retrieve or set the visible widget.
*

*
* The widget is rendered using an HTML <tt><div></tt> tag and
* does not provide styling. It can be styled using inline or external
