Each PyQt widget, which is derived from QObject class, is designed to emit ‘signal’ in response to one or more events. The signal on its own does not perform any action. Instead, it is ‘connected’ to a ‘slot’. The slot can be any callable Python function. In PyQt, connection between a signal and a slot can be achieved in different ways.

Pyqt Signals And Slots Across Threads 2
I stuck with programming as I can't find solution.
I design simple windows in qt designer .ui files.
File number 1 is main window okno1.ui and window number 2 is qwidget okno2.ui
Then I created script in python which open both windows. However I don't know how to make any communication between the windows. I would like to send some data from window one to window two and from window 2 to window one. I need simple example and explanation. Ideal for me would be if you could put some code to my script which get from list widget (window one) and put to choosen_addres label to window 2. And from window two from line edit to list widget in window one.
I do not want to convert ui to py as I plan to modify the ui files in the future.
window1 -okno1.ui is:
Window2 okno2.ui is:
My python script is:
I would be glad for any help

Hi,
I'm new to Python, and using QT to create a UI and am consequently using PyCharm to connect slots and signals.
In PyCharm I have the control parameters module. And was using it to pass away values to parameters so I can use those to do math outside the module. Looking something like this.
My problem is tho, I cant seem to do math inside the module, and whenever I try to reference the variables outside the main module I get an error. Is it possible to take them somewhere else where I can do integer arithmetic with the signals? 'Not necessarily setting number boxes (passing integers), but preferrably not limitted to.
Kind Regards,
