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 http://jeszra.sourceforge.net to generate SVG for a complete Tk-GUI. In addition. there is a python/tkinter SVG export project for the Tk canvas --search the tkinter wiki. -roger -- http://mail.python.org/mailman/listinfo/python-list

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 (http://tkinter.unpythonic.net/wiki/).

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

Comments appreciated! ~Ethan~ 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).
