// *********************************************************************
// This interface allows the Selector class to study the contents of a
// data structure it wishes to present as a selectable list, in much the
// same way as Swing model interfaces work.
// 'itemAt' and 'length' are fairly self explanatory - they are called 
// to acquire the size and content of the list.  'loaded' is used for
// data structures which may take time to load (for example those 
// coming across the network).  'loadingErrorMessage' is checked to
// see if an error occured during loading (returns !null).

	public int length();
	public int loaded();
