# This file is boilerplate TCL/TK function definitions for 'make xconfig'.
#
# CHANGES
# =======
#
# 8 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
# - Remove unused do_cmd function (part of the 2.0 sound support).
# - Arrange buttons in three columns for better screen fitting.
# - Add CONSTANT_Y, CONSTANT_M, CONSTANT_N for commands like:
# dep_tristate 'foo' CONFIG_FOO m
#
# 23 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
# - Shut vfix the hell up.
#
# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
# - Improve the exit message (Jeff Ronne).
#
# This is a handy replacement for ".widget cget" that requires neither tk4
# nor additional source code uglification.
#
proc cget { w option } {
return "[lindex [$w configure $option] 4]"
}
#
# Function to compensate for broken config.in scripts like the sound driver,
# which make dependencies on variables that are never even conditionally
# defined.
#
proc vfix { var } {
global $var

set $var 4
}
}
#
# Constant values used by certain dep_tristate commands.
#
set CONSTANT_Y 1
set CONSTANT_M 2
set CONSTANT_N 0
set CONSTANT_E 4
#
# Create a "reference" object to steal colors from.
#
button .ref
#
# On monochrome displays, -disabledforeground is blank by default; that's
# bad. Fill it with -foreground instead.
#
if { [cget .ref -disabledforeground] == "" } {
.ref configure -disabledforeground [cget .ref -foreground]
}
#
# Define some macros we will need to parse the config.in file.
