[PyQt] Basic thread question

Thank you for reading this.

Using Eric, I have created a simple GUI. This is part of the GUI class 
that includes a dial.

What I'd like to do is sweep the dial back and forth and to do this I 
can see that I need a thread so that I don't block the GUI. My question 
is, where do I place the thread class? If I place it in the same file 
after the MainWindow class, how do I then access the dial? I don't think 
the thread class is added to main_script.py. At the moment, I cannot see 
how to access the dial from there anyway.

This the Eric generated class:

class MainWindow(QMainWindow, Ui_MainWindow):
     Class documentation goes here.
     def __init__(self, parent=None):

I know that this is not totally correct, but just say that I wanted to 
step the dial point along at a one second rate. How should I proceed?

import threading
import time

class MyThread(threading.Thread):
     def __init__(self, your_string):

     def run(self):
         for i in range(100):
