[PyQt] [QTtableWidget] detect click on column header?

[Lara Michaels]

My apologies, I have figured out that I need to listen to the QHeaderView's sectionClicked(int) signal.

But I am still stuck. How do I override the function that normally does the sorting? I tried subclassing from QTableWidget and reimplementing sortByColumn(), but my function never gets called:

class MyQTableWidget(QTableWidget):

   def sortByColumn(self, col, order): 
       print 'called!'


What am I doing wrong to implement my own sortByColumn?

Many thanks for any advice
