Python and Tkinter Programming: I first encountered Python in 1993 when I joined a small company in Rhode Island. Their primary product was a GUI-builder for X/Motif that generated code for C, C++, Ada and Python. I was tasked with extending the object-oriented interface for X/Motif and Python. In the past I’d become skeptical about the use of interpretive languages, so I began the task with little excite0002ment. Two days later I was hooked. It was easy to develop interfaces that would have taken much more time and code to develop in C. Soon after, I began to choose interfaces developed using the Python interface in preference to compiled C code.

After I left the company in Rhode Island, I began to develop applications using Tkinter, which had become the preeminent GUI for Python. I persuaded one company, where I was working on contract, to use Python to build a code-generator to help complete a huge project that was in danger of overrunning time and budget. The project was a success. Four years later there are many Python programmers in that company and some projects now use Tkinter and Python for a considerable part of their code.

It was this experience, though, that led me to start writing this book. Very little documentation was available for Tkinter in the early days. The Tkinter Life Preserver was the first document that helped people pull basic information together. In 1997 Fredrik Lundh released some excellent documentation for the widget classes on the web, and this has served Tkinter programmers well in the past couple of years. One of the problems that I saw was that although there were several example programs available (the Python distribution contains several), they were mostly brief in content and did not represent a framework for a full application written with Tkinter. Of course, it is easy to connect bits of code together to make it do more but when the underlying architecture relies on an interpreter it is easy to produce an inferior product, in terms of execution speed, aesthetics, maintainability and extensibility.

So, one of the first questions that I was asked about writing Tkinter was “How do I make an XXX?” I’d usually hand the person a chunk of code that I’d written and, like most professional programmers, they would work out the details. I believe strongly that learning from full, working examples is an excellent way of learning how to program in a particular language and to achieve particular goals.

When I was training in karate, we frequently traveled to the world headquarters of Shukokai, in New Jersey, to train with the late Sensei Shigeru Kimura. Sensei Kimura often told us “I can’t teach you how to do this (a particular technique)—you have to steal it.” My approach to learning Tkinter is similar. If someone in the community has solved a problem, we need to steal it from them. Now, I am not suggesting that we infringe copyright and professional practice! I simply mean you should learn from whatever material is available. I hope that you will use the examples in the book as a starting point for your own creations. In a small number of cases I have used code or the ideas of other programmers. If this is the case I have given the original author an appropriate acknowledgment. If you use one of these pieces of code, I’d appreciate it if you would also acknowledge the original author. After all, what we “steal” has more value than what we produce ourselves—it came from the Sensei!

I was impressed by the format of Douglas A. Young’s The X Window System: Programming and Applications with Xt. It is a little old now, but it had a high proportion of complete code examples, some of which made excellent templates upon which new applications could be built. Python and Tkinter Programming has some parallels in its layout. You will find much longer examples than you may be accustomed to in other programming books. I hope that many of the examples will be useful either as templates or as a source of inspiration for programmers who have to solve a particular problem.

One side effect of presenting complete examples as opposed to providing code fragments is that you will learn a great deal about my style of programming. During the extensive reviews for Python and Tkinter Programming some of the reviewers suggested alternate coding patterns for some of the examples. Wherever possible, I incorporated their suggestions, so that the examples now contain the programming styles of several people. I expect that you will make similar improvements when you come to implement your own solutions.

hope that you find Python and Tkinter Programming useful. If it saves you even a couple of hours when you have an application to write, then it will have been worth the time spent reading the book python and tkinter programming pdf.

Tkinter is a graphical user interface (GUI) module for Python, you can make desktop apps with Python. You can make windows, buttons, show text and images amongst other things.

Tk and Tkinter apps can run on most Unix platforms. This also works on Windows and Mac OS X.
The module Tkinter is an interface to the Tk GUI toolkit.

Tkinter module

This example opens a blank desktop window. The tkinter module is part of the standard library.
To use tkinter, import the tkinter module.

This is tkinter with underscore t, it has been renamed in Python 3.


Setup the window

Start tk and create a window.

The window class is not standard, we create a Window. This class in itself is pretty basic.

Then set the window title and show the window:
