There are an number of extension widget sets to :mod:`tkinter`.

.. seealso::

`Python megawidgets <http://pmw.sourceforge.net/>`_

is a toolkit for building high-level compound widgets in Python using the

:mod:`tkinter` package. It consists of a set of base classes and a library of

flexible and extensible megawidgets built on this foundation. These megawidgets

include notebooks, comboboxes, selection widgets, paned widgets, scrolled

widgets, dialog windows, etc. Also, with the Pmw.Blt interface to BLT, the

busy, graph, stripchart, tabset and vector commands are be available.

The initial ideas for Pmw were taken from the Tk ``itcl`` extensions ``[incr

Tk]`` by Michael McLennan and ``[incr Widgets]`` by Mark Ulferts. Several of the

megawidgets are direct translations from the itcl to Python. It offers most of

the range of widgets that ``[incr Widgets]`` does, and is almost as complete as

Tix, lacking however Tix's fast :class:`HList` widget for drawing trees.

`Tkinter3000 Widget Construction Kit (WCK) <http://tkinter.effbot.org/>`_

is a library that allows you to write new Tkinter widgets in pure Python. The

WCK framework gives you full control over widget creation, configuration, screen

appearance, and event handling. WCK widgets can be very fast and light-weight,

since they can operate directly on Python data structures, without having to

transfer data through the Tk/Tcl layer.

The major cross-platform (Windows, Mac OS X, Unix-like) GUI toolkits that are

also available for Python:
