68:
69: =item $readdesk
70:
71: Indicates that mydesk.tab has been read.
72: It is set to 'done' in the BEGIN block of this module.
73:

75:
76: The elements of this array reference arrays that are made up of the components
77: of those lines of mydesk.tab that start with prim.

79: It gets filled in the BEGIN block of this module.
80:
81: =item @secondary_menu
82:
83: The elements of this array reference arrays that are made up of the components
84: of those lines of mydesk.tab that start with scnd.

91:
92: =over
93:
94: =item prep_menuitems(\@menuitem)
95:
96: This routine wraps a menuitem in proper HTML. It is used by primary_menu() and
97: secondary_menu().
98:
99: =item primary_menu()
100:
101: This routine evaluates @primary_menu and returns XHTML for the menu
102: that contains following links: About, Message, Roles, Help, Logout
103: @primary_menu is filled within the BEGIN block of this module with
104: entries from mydesk.tab
105:
106: =item secondary_menu()
107:
108: Same as primary_menu() but operates on @secondary_menu.
109:
110: =item show_return_link()
111:
112: =item registerurl()
113:
114: This gets called in the header section
115:
116: =item innerregister()
117:
118: This gets called in order to register a URL, both with the Remote
119: and in the body of the document
120:
121: =item loadevents()
122:
123: =item unloadevents()
124:
125: =item get_menu_name()
126:
127: =item clear()
128:
129: =item switch()
130:
131: Switch a button or create a link
132: Switch acts on the javascript that is executed when a button is clicked.
133: The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
