   43: 
   44: =over
   45: 
   46: =item @desklines

   48: Each element of this array contains a line of mydesk.tab that doesn't start with
   49: cat, prim or scnd. 
   50: It gets filled in the BEGIN block of this module.
   51: 
   52: =item %category_names
   53: 
   54: The keys of this hash are the abbreviations used in mydesk.tab in those lines that 
   55: start with cat, the values are strings representing titles. 
   56: It gets filled in the BEGIN block of this module.
   57: 
   58: =item %category_members

   60: TODO 
   61: 
   62: =item %category_positions
   63: 
   64: The keys of this hash are the abbreviations used in mydesk.tab in those lines that
   65: start with cat, its values are position vectors (column, row). 
   66: It gets filled in the BEGIN block of this module.
   67: 
   68: =item $readdesk
   69: 
   70: Indicates that mydesk.tab has been read. 
   71: It is set to 'done' in the BEGIN block of this module.

   80: =item %primary_sub_menu
   81: 
   82: The keys of this hash reference are the names of items in the primary_menu array 
   83: which have sub-menus.  For each key, the corresponding value is a reference to
   84: an array containing components extracted from lines in mydesk.tab which begin
   85: with primsub:.
   86: This hash, which is used by primary_menu to generate sub-menus, is populated in
   87: the BEGIN block.
   88: 
   89: =item @secondary_menu
   90: 
   91: The elements of this array reference arrays that are made up of the components

   98: =head1 SUBROUTINES
   99: 
  100: =over
  101: 
  102: =item prep_menuitems(\@menuitem)
  103: 
  104: This routine wraps a menuitem in proper HTML. It is used by primary_menu() and 
  105: secondary_menu().
  106: 
  107: =item primary_menu()
  108: 
  109: This routine evaluates @primary_menu and returns XHTML for the menu
  110: that contains following links: About, Message, Roles, Help, Logout
  111: @primary_menu is filled within the BEGIN block of this module with 
  112: entries from mydesk.tab 
  113: 
  114: =item secondary_menu()
  115: 
  116: Same as primary_menu() but operates on @secondary_menu.
  117: 
  118: =item create_submenu()
  119: 
  120: Creates XHTML for unordered list of sub-menu items which belong to a
  121: particular top-level menu item. Uses hover pseudo class in css to display
  122: dropdown list when mouse hovers over top-level item. Support for IE6
  123: (no hover psuedo class) via LC_hoverable class for <li> tag for top-
  124: level item, which employs jQuery to handle behavior on mouseover.
  125: 
  126: Inputs: 4 - (a) link and (b) target for anchor href in top level item,
  127:             (c) title for text wrapped by anchor tag in top level item.
  128:             (d) reference to array of arrays of sub-menu items.
  129: 
  130: =item innerregister()
  131: 
  132: This gets called in order to register a URL in the body of the document
  133: 
  134: =item clear()
  135: 
  136: =item switch()
  137: 
  138: Switch a button or create a link
  139: Switch acts on the javascript that is executed when a button is clicked.  
  140: The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
  141: 
  142: =item secondlevel()
  143: 
  144: =item openmenu()
  145:

  147: 
  148: =item rawconfig()
  149: 
  150: =item utilityfunctions()
  151: 
  152: Output from this routine is a number of javascript functions called by
  153: items in the inline menu, and in some cases items in the Main Menu page.
