REALbasic is a programming language in the best Macintosh tradition: visual, intuitive, and easy to learn. It allows you to create interfaces in minutes and entire, compiled applications without having to learn a complicated language; the strong object orientation makes it very easy even for beginners to develop, maintain, and alter projects. Best of all, an REALbasic 3, a single button click generates your project as a Mac OS 8/9 application, a Mac OS X native ("Carbon") application, or a Windows executable. No other application framework lets you compile for users on so many platforms so quickly and easily. "REALbasic: The Definitive Guide not only gives you a firm grasp of the program's essential concepts, but also tells you things you won't learn from the official documentation alone. If you've never programmed before, the book offers both a primer in REALbasic and an intuitive approach to the concepts of programming itself, as you quickly reach the ability to program every aspect of REALbasic. You start out drawing the interface much as you would do in a drawing program: by selecting buttons, menus, dialog boxes, and the like from a tools menu. Then you use the code editor to fill in the code that tells these pieces what to do. The widely hailed first edition of "REALbasic: The Definitive Guide has been completely rewritten to encompass reader suggestions and the many improvements of REALbasic 3--like its ability to compile and run under OS X. The book is divided into three sections: Fundamentals: a detailed summary of the language that quickly shows you how to think about programming and accomplish your goals in less time User Interface: how to create a complete application usingthe rich classes and pre-defined tools that make life so much easier for the REALbasic programmer.
