Graphical User Interfaces with Tk
*********************************

Tk/Tcl has long been an integral part of Python.  It provides a robust
and platform independent windowing toolkit, that is available to
Python programmers using the ``Tkinter`` module, and its extension,
the ``Tix`` module.

The ``Tkinter`` module is a thin object-oriented layer on top of
Tcl/Tk. To use ``Tkinter``, you don't need to write Tcl code, but you
will need to consult the Tk documentation, and occasionally the Tcl
documentation. ``Tkinter`` is a set of wrappers that implement the Tk
widgets as Python classes.  In addition, the internal module
``_tkinter`` provides a threadsafe mechanism which allows Python and
Tcl to interact.

``Tkinter``'s chief virtues are that it is fast, and that it usually
comes bundled with Python. Although its standard documentation is
weak, good material is available, which includes: references,
tutorials, a book and others. ``Tkinter`` is also famous for having an
outdated look and feel, which has been vastly improved in Tk 8.5.
Nevertheless, there are many other GUI libraries that you could be
interested in. For more information about alternatives, see the *Other
Graphical User Interface Packages* section.
