MainWindow object has no attribute 'connect'

Question

I wonder if someone could help me resolve this issue regarding slot connection in PyQt5. The following code snippet will show you what my problem is.

class M         


        

Answer 1

You are using the old style signal and slot, which is not longer supported in PyQt5.

The old style:

self.connect(origin, SIGNAL('completed'), self._show_results)

should now be written in the new style:

origin.completed.connect(self._show_results)

For more details, see the documentation on New-style Signal and Slot Support.
