Use a single model on both views. Then when the user clicks on a node (or 
activates it by some other means) in the tree view call setRootIndex() on your 
table view so that the table only shows the indexes below that root.

See:

http://doc.qt.nokia.com/4.7-snapshot/qabstractitemview.html#activated
http://doc.qt.nokia.com/4.7-snapshot/qabstractitemview.html#setRootIndex

Just connect these together and you are done.

Cheers,
