The String to display in the item renderer.
The host component of the item renderer can use the
itemToLabel() method to convert the data item
to a String for display by the item renderer.
For controls like List and ButtonBar, you can use the
labelField or labelFunction properties
to specify the field of the data item that contains the String.
Otherwise the host component uses the toString() method
to convert the data item to a String.
