PyQt5 - Get a parameter from a modal window

[Ninja2112]

Hello...I'd like some help.
I've created a main window in PyQt5 and another modal window which I need to catch a parameter from a radiobutton.
Here's the code(in the main window):

class JanelaModPag(QMainWindow):
   def __init__(self,m,items): 
     super().__init__()
     self.ui = Ui_ModPagam()
     self.ui.show()

How can I return to this with the parameter ?

You'd better post a reproducible example. Nobody knows what Ui_ModPagam contains.

This is all not reproducible.

     self.ui = Ui_ModPagam()
     self.ui.show()

Ui_ModPagam has nothing to show, there is no window.

def __init__(self,m,items): 

What is m,items?

These are the parameters that I'd like to pass to the modal...but changed my mind and forgot to delete. Decided to capture value from radio in modal and return execution to the window that calls it.

Is ModPagam supposed to act like a dialog? Making a window modal keeps it on top and keep focus, it does not make it a dialog. A dialog blocks the main window code from running until the dialog is closed. Closing the dialog is how the user tells the program that all input is entered in the dialog. To act this way, a dialog has its own exec() loop.

The best way to make a dialog is subclass the QDialog class. I don't use QtDesigner, but I found a tutorial about using designer to create dialogs.
