30: =head1 NAME
31:
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)
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.
