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

The video tutorial addresses issues in a design involving add and remove methods in a base class. It discusses the challenges faced by leaf classes that cannot implement these methods and suggests handling them by throwing exceptions. The tutorial explores alternative solutions, such as using a Getframe function to manage method calls. It also covers memory management, emphasizing the importance of deleting objects created on the heap, especially in languages without garbage collection. The responsibility of deleting children in a composite is highlighted, ensuring no memory leaks occur.

In languages without garbage collection, who is responsible for deleting UI components created on the heap?

What changes were made to ensure that the main window deletes its children in the composite design pattern?

Why is it important to check for memory leaks when implementing the composite design pattern?
