Slots and Signals in QT – how to connect from another class generate a signal from another class in another file ? generate a slot from another class in another file ? write back into the ui.py class, ie writing some text in a text field. It is no problem doing the above if I keep all the code in the ui.py file, but it does become a copy/paste issue and prone to me making simple errors. Class Qt.ConnectionType - Qt Documentation In particular, it determines whether a particular signal is delivered to a slot immediately or queued for delivery at a later time. With queued connections, the parameters must be of types that are known to Qt's meta-object system, because Qt needs to copy the arguments to store them in an event behind the scenes. Mapping Many Signals to One - doc.qt.io Qt allows us to connect multiple signals to the same signal or slot. This can be useful when we provide the user with many ways of performing the same operation.

First of all, if you have a slot which takes as an argument a class you've defined, and you want to connect a signal from a different namespace to that slot -- well, the only way I can usually get this to compile and run is to fully qualify the class in both the signal and the slot (since Qt's string-matching argument checks will otherwise fail).
