Could it be that your are missing a closing character on your signal slot?
QtCore.QObject.connect(self.filterLineEdit, QtCore.SIGNAL('textChanged(
QString'),self._proxyModel.setFilterRegExp)
Here
'textChanged( QString'
You are using new style signal slots in some places and old style in
others. Why not just use them all the time and avoid the potential typos?
self.textChanged.connect(...)
