What's Next?

As you have seen in this chapter, the Delphi class library has a few root classes that play a considerable role and that you should learn to leverage to the maximum possible extent. Some programmers tend to become expert on the components they use every day, and this is important; but without understanding the core classes (and ideas such as ownership and streaming), you'll have a tough time grasping the full power of Delphi.

Of course, in this book, I also need to discuss visual and database classes. Now that I've introduced all the base elements of Delphi (language, RTL, core classes), I'm ready to discuss the development of real applications with this tool. Chapter 5 covers the structure of the visual portion of the component library.

Following chapters are devoted to examples of using the various components to build applications with a modern user interface and use forms effectively. I'll cover the advanced use of traditional controls and menus, discuss the actions architecture, cover the TForm class, and then examine toolbars, status bars, dialog boxes, and MDI applications.
