Chapter 4: Windows, Controls, and Menus

Overview

Understanding how windows work and relate to each other is the key to understanding the user interface of the Microsoft Windows operating system, whether it be Microsoft Windows XP or Microsoft Windows CE. Everything you see on a Windows display is a window. The desktop is a window, the taskbar is a window, even the Start button on the taskbar is a window. Windows are related to one another according to one relationship model or another; they may be in parent/child, sibling, or owner/owned relationships. Windows supports a number of predefined window classes, called controls. These controls simplify the work of programmers by providing a range of predefined user interface elements as simple as a button or as complex as a multiline text editor. Windows CE supports the same standard set of built-in controls as the other versions of Windows. These built-in controls shouldn't be confused with the complex controls provided by the common control library. I'll talk about those controls in the next chapter.
