Can anyone point me to a simple example of QTableView in PySide?
I found the QTableView docs but unfortunately they don't give an example, and I'm very new to PySide, so I don't even know how to start. (I am very familiar with the JTable in Java Swing, so I know how to use table models.)
Found one:

''' ps_QAbstractTableModel_solvents.py
use PySide's QTableView and QAbstractTableModel for tabular data
sort columns by clicking on the header title
here applied to solvents commonly used in Chemistry
PySide is the official LGPL-licensed version of PyQT
tested with PySide112 and Python27/Python33 by vegaseat 15feb2013
