Structural Design Patterns in Modern C++ - User Interface (UI) Example - Part III

The video tutorial discusses enhancing design flexibility by implementing parent-child relationships in UI controls. It introduces methods to set and get parent pointers, enabling reverse traversal. The tutorial also covers using C++17 features for better scope management and handling output messages to distinguish widget types. Finally, it addresses memory management, comparing raw and smart pointers, and emphasizes careful deletion of controls to prevent memory leaks.

How does the implementation of the Composite design pattern enhance the flexibility of the design?

What is the erase-remove idiom and how does it relate to the management of UI controls?

Discuss the advantages and disadvantages of using raw pointers versus smart pointers in the context of the application described.
