Delphi for Linux (Kylix) Development includes three main themes. First, the book recognized that much of its audience will be Windows developers who need to understand basic Linux development strategies, so there will be information throughout the book offering insight on how to leverage Windows development knowledge to the Linux platform. There will be significant coverage of the tools and features of the Kylix environment, but the book assumes that readers will be familiar with RAD development tools generally. Finally, there is extensive coverage of how to apply the CLX library in building solid applications. The book will also discuss cross-platform development strategies.
