[PyQt] connection to list view and combo pyqt

[Peter Liedler]

Thanks for the hint. The signal connection to the combo Box now works.
The listView class that provides the signal selectionChanged() is
QAbstractItemView and is declared as
virtual void selectionChanged ( const QItemSelection & selected, const
QItemSelection & deselected )

So I now would connect to the signal with 
self.connect(self.listViewTitle,
SIGNAL("selectionChanged(QItemSelection, QItemSelection)"),
self.titleSelected)

That doesn't work until now, I'll try other constellations.

thx Peter
