PyQt5 converting signal code from PyQt4

Question

I'm a newbie and am having difficulty changing a line of code from PyQT4 to PyQT5, its to do with signals & slots. I suspect its because arguments are being passed to the slot.

Original line was:

self.connect(self.assetView.selectionModel(), SIGNAL(("currentRowChanged(QModelIndex,QModelIndex)")),self.assetChanged)

I’ve tried:

self.assetView.selectionModel.currentRowChanged(QModelIndex,QModelIndex).connect(self.assetChanged)

and I get: AttributeError: 'builtin_function_or_method' object has no attribute 'currentRowChanged'

self.assetView is a QTableView and self.assetChanged has def:

  def assetChanged(self, index):

Grateful for any help

The new syntax is as follows:

sender.signal.connect(some_slot)

In your case:

self.assetView.selectionModel().currentRowChanged.connect(self.assetChanged)

#   ^^^^^^^^^sender^^^^^^^^       ^^^^signal^^^^            ^^^^^^slot^^^^^^

and

def assetChanged(self, current, previous):
    print(current, previous)
