# Tix.py -- Tix widget wrappers, part of PyTix.
#
#	- Sudhir Shenoy (sshenoy@gol.com), Dec. 1995.
#	  based on an idea (and a little code !!) of Jean-Marc Lugrin
#						     (lugrin@ms.com)
#
# NOTE: In order to minimize changes to Tkinter.py, some of the code here
#	(TixWidget.__init__) has been taken from Tkinter (Widget.__init__)
#	and will break if there are major changes in Tkinter.
#
# The Tix widgets are represented by a class hierarchy in python with proper
# inheritance of base classes.
#
# As a result after creating a 'w = StdButtonBox', I can write
#		w.ok['text'] = 'Who Cares'
#    or		w.ok['bg'] = w['bg']
# or even	w.ok.invoke()
# etc.
#
# Compare the demo tixwidgets.py to the original Tcl program and you will
# appreciate the advantages.
