<h3>
The Tkinter Module</h3>
<p>Tkinter is Python's <i>de facto</I> standard GUI
toolkit. It's the most cross-platform GUI. Many applications are written using
Tkinter because it is a very powerful and flexible tool. Maybe the most notable
features are its geometry management, which is much better than standard
windows, and its efficient Text and Canvas widgets. Many toolkits support as
good as or better geometry management (some of them are listed in this
chapter).</P>
<P>Tkinter, which stands for <I>Tk interface,</i> is the
standard Python interface to the Tk GUI toolkit from
<a naME="idx1073748179"></A>Ajuba (formerly
<A name="idx1073748180"></A>Scriptics). Tkinter is a binding to Tcl/Tk that in former
days was developed by Sun Labs. Actually it works on top of Tcl/Tk. To use
Tkinter, you don't need to write Tcl code. Occasionally, you will need to
consult the Tk documentation and the Tcl documentation because Tk's low-level
event handling mechanism is considered part of Tcl.</P>
<P>Both Tk and Tkinter are available on most UNIX platforms, as well
as on Windows and Macintosh systems. Some platforms come with Tcl/Tk as an
optional part of the OS distribution or, in the case of Win32, as part of the
Python install. Quite a lot of Linux distributions (and other free UNIX-like
Operation Systems) install Tcl/Tk by default. Starting with the 8.0 release, Tk
offers a native look and feel on all platforms.</P>
<p>If you ask yourself why you should use Tkinter, I would say that it
is a mature and reliable solution for graphic applications, running on every
platform where it is possible to run Tcl/Tk, which is basically every platform,
but Macintosh. Tkinter and Macs are still negotiating a healthy version.</p>
<p>One of the most important reasons why Tkinter was chosen to be the
official GUI option is because it seems to have a long life ahead of it. Many
people are against this, but the fact is that Tkinter is available for Windows,
UNIX, and Macintosh platforms, and being part of the Official Python
distribution puts it in a position of constant upgrading.</p>
<p>Tkinter is probably the most documented Python GUI that you will
find. As you can see in
<a href="206.html">Chapter 15</a>, there is a respectable
knowledge base available for you, given its <i>de facto</i>
standard status.</p>
<p>See the Tkinter documentation page on
<a targEt="_blank" hRef="http://www.python.org/">http://www.python.org/</a> for
more up-to-date information about this toolkit.
