How does child management works in Qt?

Answer 1

In Qt, child management is handled through QObject's parent-child relationship. When a QObject is created with a parent, it automatically becomes a child of that parent, which ensures that when the parent is deleted, all its child objects are also deleted, preventing memory leaks. This hierarchical structure allows for organized ownership and simplifies resource management in applications. Additionally, child objects can signal their parent when specific events occur, facilitating communication within the object hierarchy.
