Design patterns are a very exciting tool in your software development toolbox. Learn how to incorporate them in your code.
- [Instructor] In the previous video,…we saw when not to use OOP.…We're now discussing how to use design patterns.…In this video, we will create widgets…for our Python GUI by using the factory design pattern.…In previous videos, we created our widgets…either manually, one at a time,…or dynamically, in a loop.…Using the factory design pattern,…we will use the factory to create our widgets.…
We will create a Python GUI which has three buttons,…each having different styles.…Towards the top of our Python GUI module,…just below the import statements,…we create several classes.…We create a base class,…which our different button style classes inherit from,…and in which each of them overrides the relief…and foreground configuration properties.…
All subclasses inherit the getButtonConfig method.…From this base class, this method returns a tuple.…We also create a ButtonFactory class…and a list that holds the names of our button subclasses.…We name the list buttonTypes…as our factory will create different types of buttons.…
