how to access members from a class

Question

im using QtDesigner which drops its code in a Class when converted to .py.

I have to access the buttons and labels and textboxes outside of the class to do operations on them. I cant put my functions above the class because of unresolved error. I dont want to add my functions inside the class.. theres alot of stuff and its messy. so i have to put my functions after the class.

here is a over simplified sample python code structure that Qt Designer converts to

class MyWindowUI():
    def setupUI(self):
        self.myButton1 = 'A'
        self.myButton2 = 'B'

    def stuff(self):
        self.myButton3 = 'A'
        self.myButton4 = 'B'
    test = "something"

myBtn = MyWindowUI()
print (myBtn.test)
print (myBtn.myButton4)

so, myBtn.test works. it prints 'something', but, myBtn.myButton4 doesnt. Says MyWindowUI instance has no attribute 'myButton4.

How do I get information from "stuff" and "setupUI" from outside the class?

Since you are not calling methods, your code never enters those code blocks to create variables.

One way is calling them in __init__ but you can call them anywhere you like after creating your class instance. Just be sure, your code goes through that line.

class MyWindowUI():
    def __init__(self):
        self.setupUI()
        self.stuff()

    def setupUI(self):
        self.myButton1 = 'A'
        self.myButton2 = 'B'

    def stuff(self):
        self.myButton3 = 'A'
        self.myButton4 = 'B'
    test = "something"

myBtn = MyWindowUI()
#myBtn.setupUI()
#myBtn.stuff()
print (myBtn.test)
print (myBtn.myButton4)
