[PyQt] Emit parameter of QStandardItemModel

[Maurizio Berti]

Maybe I've not understood correctly the question, but if you know the row
and column of the item for which you want to emit the notification, it
should be as simple as:

self.model.itemChanged.emit(self.model.item(row, column))

If you only have the index, you can access the item through the
itemFromIndex() method.
