# Sets default configuration options for plplot/TK driver.
# Maurice LeBrun
# IFS, University of Texas
#
# It is very easy to customize plplot/TK settings for a particular site
# or user.  The steps are:
#
# 1. Create a directory for holding app-defaults files.  $HOME/app-defaults/
#    is a good choice.  Then set the XAPPLRESDIR environmental to this
#    pathname (keep trailing slash).
#
# 2. Create a plplot app-defaults file by the name of PLplot or plplot (PLplot
#    is loaded last and thus has preference, if both exist).  It should use
#    standard X11 resource syntax.
#
# 3. If you wish to load resources based on a different class name, you should
#    call loadAppDefaults with suitable arguments after the pldefaults call.
#
# The older syntax using the plconfig.tcl file may still work but is
# deprecated. 
#
# BUGS:
#  - should probably replace some of the global variables with resources.
#
# Use something like this for widget font settings:
# option add Tk.BoldFont "*-lucida sans-Bold-R-Normal-*-100-*" widgetDefault
#
#----------------------------------------------------------------------------

# From the TK FAQ, and modified to taste.

# pl_getenv varName
#   Looks up the environment variable named $varName and returns its value
#   OR {} if it does not exist

proc pl_getenv varName {
    global env
    if {[info exists env($varName)]} { return $env($varName) }
}

# loadAppDefaults classNameList ?priority?
#   Searches for the app-default files corresponding to classNames in
#   the order specified by X Toolkit Intrinsics, and loads them with
#   the priority specified (default: startupFile).  Stops after first
#   file found for each class.
