For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Tkinter - an easy to use Python Graphic User Interface - introductory examples

Tkinter (tkinter from Python 3.0 - note the different case) is a graphic user interface (GUI) that's included with the Python distribution. It's a lightweight wrapper around the Tk Toolkit - frequently used with Tcl too - and it provides a very quick and easy way to replace user-facing command line interfaces with interaction windows with buttons, labels, sliders, text entry boxes, etc.

I've added a "Hello GUI World" example using Python and Tkinter to our web site - a program showing the very first basics. Source code [here]. It's as easy as ...

Set up a root window:

  root = Tkinter.Tk()

Add a couple of components into that window, and display them:

  Tkinter.Label(text='Hello GUI World').pack()
  Tkinter.Button(text='exit', command = sys.exit).pack()


And wait for the user to do something (alas, all we have provided for him in this simple example is an "exit" button!)

  root.mainloop()


Moving on to a more complete first practical example of a GUI (source code [here]), I've provided examples of each of the major stages of a GUI:
• Setting up widgets
• Arranging widgets in a geometry
• Acting when widgets are used (e.g. buttons pressed)
• providing feedback within the GUI's window

Our Python Courses overview the various GUIs available and include short intriductory demos such as the ones above. If you want to study any particuar GUI in more detail, let us know in advance (for a private course) or ask us to run an "extra day" for you after our public course. We have a great deal of material available on Tk, and plenty on Qt and wx too, but as only a small proportion of delegates uses each we can't justify their full and detailed coverage for everyone on a public course.
