List/TreeWidget vs. List/TreeView?

[Alabaster]

Python 3 / Windows 7

I'm still learning Python & PyQt and so far I've been using the ListWidget and TreeWidget. I get the impression that ListView and TreeView are more powerful or flexible in some way but I can't seem to find the pros and cons of each. Can anyone enlighten me on what situations I may find ListView / TreeView to be better than the Widget versions? (Or simply point me in the direction of an explanation if there's one already written -- I can't seem to find one).

Thanks

Views works on model, widget versions works on inserted items.
