wxWidgets and Object-Oriented Programming

Like all modern GUI frameworks, wxWidgets benefits from heavy use of object-oriented programming concepts. Each window is represented as a C++ object; these objects have well-defined behavior, and can receive and react to events. What the user sees is the visual manifestation of this interacting system of objects. Your job as a developer is to orchestrate these objects' collective behavior, a task made easier by the default behaviors that wxWidgets implements for you.

Of course, it's no coincidence that object-oriented programming and GUIs mesh wellthey grew up together. The object-oriented language Smalltalk designed by Alan Kay and others in the 1970s was an important milestone in GUI history, making innovations in user interface technology as well as language design, and although wxWidgets uses a different language and API, the principles employed are broadly the same.
