Help me understand this... (Classes and self).

[Ceegen]

I am trying to understand the process by which widgets are added to the GUI using classes in this manner.

You really should spend some time learning about classes in general.
a widget is a class as a matter of fact everything in python is a class
To show this, consider this example:

>>> a = 5
>>> type(a)
<class 'int'>
>>>

a is an instance of class int
as for widgets:

>>> import tkinter
>>> root = tkinter.Tk()
>>> type(root)
<class 'tkinter.Tk'>
>>> label_a = tkinter.Label(text='abc')
>>> type(label_a)
<class 'tkinter.Label'>
>>> # If you want to see methods and attributes for Label:
>>> help(tkinter.Label)
...

here are some tutorials on classes:
Class Basics
Class Intermediate: Inheritance
Class Intermediate: Operator Overloading
Classes [advanced]: Dependent attributes (and Descriptors)
Classes [advanced]: Descriptors (managed attributes)

Reading up...

Search results for OOP and Python related material is flooded with all sorts of Udemy-related things. The docs don't seem to explain things in a way I can understand it, as most documentation I've seen tries to explain as little as possible.

what determines which frame that widget belongs to?

when a widget is created it is passed a parent, the created widgets __init__ method then set the passed in widget as it parent, the widget then belongs to the passed in parent.

Okay. I'm going to go try a few things now in the code and see if I really understand what you're saying.

If I have any more questions as a result of that, I'll just come back to this thread.


Thanks x2.
