From the top down:
- Your App Here (Python)
- A Python application makes a Tkinter call.
- Tkinter (Python Module)
- This call (say, for example, creating a button widget), is
implemented in the Tkinter module, which is written in
Python. This Python function will parse the commands and the
arguments and convert them into a form that makes them look as if they
had come from a Tk script instead of a Python script.
- tkinter (C)
- These commands and their arguments will be passed to a C function
in the tkinter - note the lowercase - extension module.
- Tk Widgets (C and Tcl)
- This C function is able to make calls into other C modules,
including the C functions that make up the Tk library. Tk is
implemented in C and some Tcl. The Tcl part of the Tk widgets is used
to bind certain default behaviors to widgets, and is executed once at
the point where the Python Tkinter module is
imported. (The user never sees this stage).
- Tk (C)
- The Tk part of the Tk Widgets implement the final mapping to ...
- Xlib (C)
- the Xlib library to draw graphics on the screen.
Release 2.4.2, documentation updated on 28 September 2005.
