Event-driven programming--the foundational blocks supporting graphical user interfaces, for one--has always been a perfect showcase for, and a driving mechanism behind the development of, object-oriented languages. This comprehensive text approaches the subject of OOP from a compare-and-contrast angle. Assuming a year or so of experience in one object-oriented language, it begins with the overview of OOP concepts, such as inheritance and polymorphism, and covers the basics of event-driven programming in general, before commencing with a series of chapters, each analyzing a specific OOL in more detail, its strengths, weaknesses and peculiarities. Languages covered include Smalltalk (with the Squeak environment), C++ and Java (including the Swing library), C# and the Common Language infrastructure, and Python. A chapter in the middle of the book describes Visual Studio and Microsoft foundation classes. Answers to odd-numbered exercises and a CD-ROM containing figure and source files for all chapters are included. Annotation ©2014 Ringgold, Inc., Portland, OR (protoview.com)
