"... a clearly-written, well organized, approachable yet technically complete treatment of Delphi component development. It's a marvelous book and I recommend it without reservation."
Jerry Coffey, Editor-in-Chief
Delphi Component Design tells the inside story of how and why Delphi was built, and how to make use of this information to build better Delphi components and applications. Whether you're a Delphi application writer yearning to expand into component writing, or you're an experienced Delphi component writer in pursuit of the smaller, faster, better Holy Grail, Delphi Component Design will help you sort out what Delphi Visual Component Library (VCL) services can do for you (and how they do it); what your components can do for VCL; what standard behaviors your component classes must implement; and how to take advantage of little-known VCL classes and services to dramatically improve your component's ease-of-use, code reuse, flexibility, and performance.
Delphi Component Design's three major sections mirror the phases of component creation -- Analysis and Design, Implementation Details, and Design-Time Tools. Part 1, Analysis and Design, reviews the critical steps of component design, including object decomposition analysis, component aggregation, implementation abstraction techniques, and extensibility issues. Part 2, Implementation Details, examines the nitty-gritty specifics of Delphi's most powerful and most mysterious subsystems (including polymorphism, exceptions, component streaming, messaging, graphics, OLE, and more) in complete detail, so that your components can take maximum advantage of Delphi's built-in services. Part 3, Design-Time Tools, shows you how to write property and component editors to make building applications with your most complex components a snap, and how to build experts and add-in tools to seamlessly merge your own development tools and helper apps into the Delphi development environment.
This is the no-stone-unturned authority on building advanced Delphi components, from high-level views of how a component fits into the grand scheme of things down to the minute details of how each link between a component and the rest of the system works, from design-time support tools to run-time performance optimizations.
