Object Oriented Programming

The object oriented programming is a technique invented as a response for two trends in the computer market. The first one was increasing complexity of software. Management of a traditionally written code becomes harder when the code size increases. The second trend was increasing popularity of graphical user interfaces, which meant the end of the sequential execution of programs. Instead modern programs are event driven, it means the flow of code is determined by external events (like an user input) and is not known at a time of writing the program. Object oriented programming divides a program into a set of objects interacting with each other using well defined interfaces. Such a modularization simplifies the management of project and also fits naturally the concept of modern graphical user interfaces. User controls (called "gadgets" in MUI) are just objects in the code and interact with objects representing user data.
