# This file contains all procedures related to listboxes.
# In PBS's GUI:
#	a listbox can have 
#		one or more entries, 
#	and each entry is made up of a
#		number of field values separated by one or more white spaces. 
#       A field is referred to as 
#		the index # representing the corresponding field value.
# The terms "entry", "field", "fieldval" will be used to represent listbox
# elements.
#
################################################################################
# buildFullListbox: a procedure that automates the creation of a complete
# listbox using the "listbox" widet command.
# INPUT: frame_name          - the name of the frame widget where to place the
#				complete listbox.
#        ColxRow             - # of columns (characters) and # of rows
#				lines on the the listbox. Must have the
#				format, <number>x<number>  
#	  header_str          - the header string of the listbox.
# 	  scrollbarType       - specifies the orientation of the listbox's
#			        scrollbar. Can only have the values:
#				xscroll, yscroll, xyscroll, noscroll.
# IF header_str is the empty "" string, then the listbox will have no header
# meaning, even the select all/deselect all button will not be placed.
# 	
# OPTIONS:
#	all_button		- if you want the "Select All/Deselect All" to
#				  be included. 
#	header_at_left		- if you want the header string to be at the
#				  left side of the listbox.

# get_keyvals: Procedure that returns a formatted string containing field
# values (indexes specified in 'key_list') of a listbox, 'lbox'. The format of
# string puts 'inner_sep' within key values of an entry, and 'outer_sep' 
# between entries of the listbox. The entries of the listbox that will be
# checked can be either "all" or "select".
#
# Ex. suppose you have a listbox, lbox1, whose key is a pair: 
#     {column_0 column_6}.  The idea is to return the string:
#
#	"entry0_key0val@entry0_key6val|entry1_key0val@entry1_key6val}|.."
#     Do this by calling the procedure as follows:
#	   get_keyvals lbox1 {0 6} "@" "|" "all"
#
# CAUTION: This procedure returns a list of elements ACCORDING to its 
# increasing entry position in the list box.
# So returning "elem1 elem2 elem3" means 'elem1' appears in the listbox before
# 'elem2', and 'elem2' appears before 'elem3', and so on.
