RE: [Java-gnome-developer] Problems with TreeView

[Jeffrey M. <Jef...@Br...>]

I forgot to mention that there was an API change with
this fix.  I renamed the TreeStore method moveIterNext
to getNextIter and the method now returns a TreeIter
or null if at the end of the list.  This allows you
to do the following:

TreeIter anIter = listStore.getFirstIter();

	while (anIter != null) {
		// do something here
		anIter = listStore.getNextIter(anIter);
	}
