Tkinter GUI Programming by Example

Overview of this book

Tkinter is a modular, cross-platform application development toolkit for Python. When developing GUI-rich applications, the most important choices are which programming language(s) and which GUI framework to use. Python and Tkinter prove to be a great combination. This book will get you familiar with Tkinter by having you create fun and interactive projects. These projects have varying degrees of complexity. We'll start with a simple project, where you'll learn the fundamentals of GUI programming and the basics of working with a Tkinter application. After getting the basics right, we'll move on to creating a project of slightly increased complexity, such as a highly customizable Python editor. In the next project, we'll crank up the complexity level to create an instant messaging app. Toward the end, we'll discuss various ways of packaging our applications so that they can be shared and installed on other machines without the user having to learn how to install and run Python programs.

Unexplored widgets


Before we begin packaging up our application, let's have a quick look at some widgets which we have not seen yet. While reading about these widgets, have a think about how you could implement them in one of our existing applications.

The LabelFrame widget

The LabelFrame widget is included with your normal tkinter import and also has a ttk version. Its purpose is to write a label and draw a border around a group of widgets. The label can be either some static text or a reference to a Label widget.

To demonstrate a possible use of this widget, let's make a small script:

import tkinter as tk
import tkinter.ttk as ttk

win = tk.Tk()
name_frame = ttk.Frame(win)
address_frame = ttk.Frame(win)

name_label_frame = ttk.LabelFrame(name_frame, text="Name")
address_label = ttk.Label(win, text="Address")
address_label_frame = ttk.LabelFrame(address_frame, labelwidget=address_label)

Our demonstration window will contain some information collection fields for the user's name and address....
