Programming Python, Second Edition

The End of the Tutorial

In this chapter, we have learned the core concepts of Python/Tkinter programming, and met a handful of simple widget objects along the way -- labels, buttons, frames, and the packer geometry manager. We’ve seen enough to construct simple interfaces, but have really only scratched the surface of the Tkinter widget set.

In the next two chapters, we will apply what we’ve learned here to study the rest of the Tkinter library, and learn how to use it to generate the kinds of interfaces you expect to see in realistic GUI programs. As a preview and roadmap, Table 6-1 lists the kinds of widgets we’ll meet there, in roughly their order of appearance. Note that this table lists only widget classes; along the way, we will also meet a few additional widget-related topics that don’t appear in this table.

Table 6-1. Tkinter Widget Classes

Widget Class	Description
Label	A simple message area
Button	A simple labeled pushbutton widget
Frame	A container for attaching and arranging other widget objects
Toplevel, Tk	A new window managed by the window manager
Message	A multiline label
Entry	A simple single-line text-entry field
Checkbutton	A two-state button widget, typically used for multiple-choice selections
Radiobutton	A two-state button widget, typically used for single-choice selections
Scale	A slider widget with scalable positions
