QUESTION
I am working on Object Oriented Design Principles and Heuristics.
In the remarkable book named Object-Oriented Design Heuristics By Arthur J. Riel (1996) I see this heuristic:
Heuristic 4.13: A class must know what it contains, but it should never know who contains it. Based on J.Reil, The main reason is reusability.
But in Swing Structure, we can access directly to the reference of Parent object.
for example: label.getParent()
So my question is:
Why swing components have .getParent() method?
Which Object Oriented Priciples or Heuristics are behid of existing this method?

Answered 2017-Nov-26 at 20:46Two things here: no rules are cast in stone in software engineering. It is always about balancing different aspects that are somehow competitive.
Then: the main purpose of UI components is (surprise) to be used in UIs. And typically any UI element belongs to exactly one parent. You can't have the same table showing up in two windows (maybe the same data, but not the UI table objects!). And from there: getting to the parent of a UI component is something that you need all the time. UI elements are always owned - and it is much more convenient when you can go up and down easily.
Long story short: I think you are looking at a very special case here - where it simply makes a lot of sense to deviate from a rule written in some book.

Install reil
You can use reil like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
