Part III.  Tk Basics

Chapter 22. Tk by Example

This chapter introduces Tk through a series of short examples. The ExecLog runs a program in the background and displays its output. The Example Browser displays the Tcl examples from the book. The Tcl Shell lets you type Tcl commands and execute them in a slave interpreter.

Tk provides a quick and fun way to generate user interfaces. In this chapter we will go through a series of short example programs to give you a feel for what you can do. Some details are glossed over in this chapter and considered in more detail later. In particular, the pack geometry manager is covered in Chapter 23 and event bindings are discussed in Chapter 26. The Tk widgets are discussed in more detail in later chapters.
