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:

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.

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:
146: =item inlinemenu()
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.
154:
155: =item serverform()
156:
157: =item constspaceform()
