Normally the list widget shows scrollbars and since this is the default
behaviour you need to do some extra lifting to getting things done.
First you can use the "addItem" and "removeItem" events to get informed that
an list item was added / removed.
You can attach a listener method with the following code
--snip--
// "this" refers to the list widget
var containerHeight = this.getChildrenContainer().getSizeHint().height;
this.setHeight(containerHeight + (this.getInsets().top * 2) + 16);
--snip--
Don't ask me where the "16" pixels coming from. I simply played with the
values to prevent the scrollbar to be shown.
Hope that helps,
Alex
