   32: Apache::lonmenu
   33: 
   34: =head1 SYNOPSIS
   35: 
   36: Loads contents of /home/httpd/lonTabs/mydesk.tab, 
   37: used to generate inline menu, and Main Menu page. 
   38: 
   39: This is part of the LearningOnline Network with CAPA project
   40: described at http://www.lon-capa.org.
   41: 
   42: =head1 GLOBAL VARIABLES
   43: 
   44: =over
   45: 
   46: =item @desklines
   47: 
   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
   59: 
   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.
   72: 
   73: =item @primary_menu
   74: 
   75: The elements of this array reference arrays that are made up of the components
   76: of those lines of mydesk.tab that start with prim:.
   77: It is used by primary_menu() to generate the corresponding menu.
   78: It gets filled in the BEGIN block of this module.
   79: 
   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
   92: of those lines of mydesk.tab that start with scnd.
   93: It is used by secondary_menu() to generate the corresponding menu.
   94: It gets filled in the BEGIN block of this module.

   98: =head1 SUBROUTINES
   99: 
  100: =over
  101: 
  102: =item prep_menuitems(\@menuitem,$target,$listclass,$linkattr)
  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 a two item array, 
  110: with the array elements containing XHTML for the left and right sides of 
  111: the menu that contains the following links: About, Message, Roles, Help, Logout 
  112: @primary_menu is filled within the BEGIN block of this module with 
  113: entries from mydesk.tab
  114: 
  115: =item secondary_menu()
  116: 
  117: Same as primary_menu() but operates on @secondary_menu.
  118: 
  119: =item create_submenu()
  120: 
  121: Creates XHTML for unordered list of sub-menu items which belong to a 
  122: particular top-level menu item. Uses hover pseudo class in css to display
  123: dropdown list when mouse hovers over top-level item. Support for IE6 
  124: (no hover psuedo class) via LC_hoverable class for <li> tag for top-
  125: level item, which employs jQuery to handle behavior on mouseover.
  126: 
  127: Inputs: 6 - (a) link and (b) target for anchor href in top level item,
  128:             (c) title for text wrapped by anchor tag in top level item,
  129:             (d) reference to array of arrays of sub-menu items,
  130:             (e) boolean to indicate whether to call &mt() to translate 
  131:                 name of menu item,
  132:             (f) optional class for <li> element in primary menu, for which
  133:                 sub menu is being generated.
  134: 
  135:  The underlying datastructure used in (d) contains data from mydesk.tab.
  136:  It consists of an array which has an array for each item appearing in
  137:  the menu (e.g. [["link", "title", "condition"]] for a single-item menu).
  138:  create_submenu() supports also the creation of XHTML for nested dropdown
  139:  menus represented by unordered lists. This is done by replacing the
  140:  scalar used for the link with an arrayreference containing the menuitems
  141:  for the nested menu. This can be done recursively so that the next menu
  142:  may also contain nested submenus.
  143: 
  144:  Example:
  145:  [											# begin of datastructure
  146: 	["/home/", "Home", "condition1"], 		# 1st item of the 1st layer menu
  147: 	[										# 2nd item of the 1st layer menu
  148: 		[									# anon. array for nested menu
  149: 			["/path1", "Path1", undef], 	# 1st item of the 2nd layer menu
  150: 			["/path2", "Path2", undef], 	# 2nd item of the 2nd layer menu
  151: 			[								# 3rd item of the 2nd layer menu
  152: 				[[...], [...], ..., [...]],	# containing another menu layer
  153: 				"Sub-Sub-Menu",				# title for this container
  154: 				undef
  155: 			]
  156: 		],									# end of array/nested menu
  157: 		"Sub-Menu",							# title for the container item
  158: 		undef
  159: 	]										# end of 2nd item of the 1st layer menu
  160: ]
  161: 
  162: =item innerregister()
  163: 
  164: This gets called in order to register a URL in the body of the document
  165: 
  166: =item clear()
  167: 
  168: =item switch()
  169: 
  170: Switch a button or create a link
  171: Switch acts on the javascript that is executed when a button is clicked.  
  172: The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
  173: 
  174: =item secondlevel()
  175: 
  176: =item openmenu()
  177: 
  178: =item inlinemenu()
  179: 
  180: =item rawconfig()
  181: 
  182: =item utilityfunctions()
  183: 
  184: Output from this routine is a number of javascript functions called by
  185: items in the inline menu, and in some cases items in the Main Menu page.
