Python and Tkinter Programming on. Grayson's deeply thought. If you're looking for a free download links of Python and Tkinter Programming pdf.
I have a copy - which I haven't read now for some years:-) But it was an excellent introduction to using Python and Tkinter and depending on your level of experience, I would highly recommend it even now to anybody who is just beginning to use Python and Tkinter. In fact, I still loan it to any friends who are just starting out with Python and want to do their first GUI. Besides, the book is mainly about using Python with Tkinter - and Tkinter hasn't changed that much since 2000, so I believe it is just as relevant today as it was back then. The fact it was written back when Python was 1.52 is probably not relevant either as it isn't a book about learning Python (all such books quickly become 'dated' given the speed at which Python develops) but rather producing GUIs using Python and Tkinter - so it still does an excellent job for that even though I have abandoned the GUI application framework that John provides in his book (I used it once for my first GUI, but these days use Pmw more for my GUIs).

That certainly isn't my impression of the themed widgets, I was of the impression that the themed widgets just added some convenient widgets (such as Scale, Spinbox etc) which a user could find in other GUI frameworks, for example, Pmw supplemented the basic Tkinter widget set and offered some (essential IMO) widgets that were missing in Tkinter - such as the Notebook widget. But I'll bow to your greater knowledge on the point on whether ttk themed widgets are a 'change' to Tkinter. Lets face it, if somebody wants to get up to speed on Python and GUI development then the book is still very, very relevant and necessary (IMO).
The documentation for the themed widgets still leaves a lot to be desired from the perspective of somebody who wants to start using Python to create GUI applications. As Lord Eldritch reminded me in his post, the book even has a section on Pmw - which is what I use mainly for my GUI applications - because Tkinter was missing some vital widgets that are now available in the ttk themed set. Personally I will start to incorporate some of the ttk themed widgets into my applications - but Pmw will remain the 'basis' for my GUI's as the entire framework (IMO) supports a class oriented approach that allows easy creation of extensible and reconfigurable (at run time) GUI interfaces. Ultimately Grayson does a good job of providing information and reference to toolkit(s) that allow a beginner to quickly get up to speed on producing a GUI using Python. It is purely up to the user afterwards as to whether they stick with Tkinter/Pmw (and now the ttk themed set) or venture into wxPython or Jython (as two examples of GUI 'systems' that provide 'better' facilities to a Python programmer).

I'd say that Tkinter has substantially changed - with the introduction of the 'ttk' themed widgets. I cover these in my tutorial at Mark But is the ttk themed widgets a 'change' to Tkinter or an 'addition/ improvement'?

It's both a change and an improvement.
The themed widgets can be used in conjunction with the traditional widgets, but in many cases it's possible (and desirable) to update your entire application to use the themed widgets. Lets face it, if somebody wants to get up to speed on Python and GUI development then the book is still very, very relevant and necessary (IMO).

PMW is certainly a helpful addition to the Tkinter developer's toolbox, but it also has limitations. It suffers from some of the same limitations as Tk itself, i.e.
It is rather dated in appearance, and even it lacks some modern UI features such as a good multicolumn listbox, treeview, etc. In addition to the ttk themed widgets, other, more configurable pure Tk-based megawidget packages exist, such as BWidgets and Tablelist, and there are Python wrappers for these at the Tkinter wiki.

Another book I've found very helpful for learning Tkinter is Programming Python by Mark Lutz-a lot of coverage there of GUI development.Kevin - Kevin Walzer Code by Kevin Peter 21.01.10 13:30. Another possible consideration when choosing a GUI to learn Python - will you want to print from within your GUI application? Admittedly, I haven't looked to see whether this situation has changed or not for some years now, but a GUI based on Tkinter (whether it is ttk or Pmw or whatever) has no support for 'printing'. Other GUI frameworks, such as wxPython, Jython, PyQT etc have API's that allow printing of information from within your GUI application.
Now if you go the Tk route, I am sure you can use the Win32 bindings to do printing - but I personally could never work them out:-) Maybe there is some reasonable documentation or example code for doing that these days - but there wasn't when I first approached the problem (which was back in the python 2.1 days - ancient history!). Printing using Windows API was a complete mystery to me.
My first GUI application required information to be printed out - I wrote the whole thing using Pmw and Tkinter - only to find that I had no way of getting stuff to a printer (I was learning Python and Tkinter at the time:-)). I briefly explored 'porting' my application to wxPython or Jython because both frameworks provided printer API functions - at that time, PyQT was commercial license only for a PC, so that wasn't an option. I found wxPython stunningly hard to understand from the documentation (I have since purchased wxPython in Action by Rappin and Dunn but have never found the time to read it). I had some problems porting the code to Jython (my code relied heavily on the pickle module and Jython had some severe bugs in that area at the time), so in the end I came up with a fairly micky-mouse system that placed information that required printing into.txt files and the GUI application started Microsoft Word using mail-merge templates and I got the information to the printer that way - not ideal! But it worked:-) So consider that in your decision process - maybe somebody can (kindly:-)) hop in here and say 'that's easy, just look at xyz or read this book abc' to find out how to print from within an application using Tkinter.

Many thanks to all who responded, especially for the reminder of the gui sections in Programming Python (forgot I had that book!). I'll start by going over that again, and we'll see how confident I feel afterwards.;) Ethan Pradeep B 29.05.10 6:09. Is printing from GUI still a 'not-happening' thing with Tkinter? I have just started learning it. Tkinter doesn't wrap native printing API's. There are a few extensions that do it, but they are platform specific and not complete. The usual ways of printing are like this: 1.
If you're outputting data from the text widget, write that to a temporary text file and print via lpr. If you're outputting data from the canvas, write that to a temporary postscript file and print via lpr. This is on Unix/MacOS. Not sure what the equivalent API on Windows is.Kevin - Kevin Walzer Code by Kevin Pradeep B 31.05.10 6:01.

Native printer dialogs do exist for both platforms. When you do not need a printer dialog: Convert the Tk-GUI to SVG, then wrap it into a fo-xml wrapper -fo accepts inline SVG- and use fop for printing. This approach works cross-platform, albeit you need a Java intallation (fop is a Java application). You can use to generate SVG for a complete Tk-GUI.
There is a python/tkinter SVG export project for the Tk canvas -search the tkinter wiki.
