#
#	Description: Package for making Tk apps use the CDE/KDE/Gnome/Windows scheme
#	Prefix: wm_default::
#	Url: http://tix.sourceforge.net/Tixapps/
#
# Usage:
#	It should be sufficient at the beginning of a wish app to simply:
#
#	    package require wm_default
#	    wm_default::setup
#	    wm_default::addoptions
#
# 	wm_default::setup takes an optional argument - the scheme if already
#	known, one of: windows gnome kde1 kde2 cde kde
# 	wm_default::addoptions takes optional arguments - pairs of variables
#	and values to override the kde settings. e.g. 
#		wm_default::addoptions -background blue
#
# Description:
#       package for making Tk apps look nice under CDE or KDE or Windows
#
#	The stuff below attempts to use the options database and the
#	various files under ~/.dt, $DTHOME, and /usr/dt to figure out
#	the user's current font and color set.  It then uses tk's
#	palette routines to set sensible defaults, and then override
#	some of the options to try to make them look like CDE.
#
#	There really *must* be an easier way to get text background
#	colors and the radiobutton highlight colors out of the
#	options database or winfo atom...  Unfortunately, I can't
#	figure out how...

# This package is based on the cde package by D. J. Hagberg, Jr.:
