There are an number of extension widget sets to Tkinter.
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 HList widget for drawing trees.
Tk is not the only GUI for Python, but is however the most commonly used one.
wxWindows is much richer in widgets than Tkinter, with its help system, sophisticated HTML and image viewers, and other specialized widgets, extensive documentation, and printing capabilities.
Even though FOX offers a large collection of controls already, FOX leverages C++ to allow programmers to easily build additional Controls and GUI elements, simply by taking existing controls, and creating a derived class which simply adds or redefines the desired behavior.
