=head1 NAME
Apache::lonmenu
=head1 SYNOPSIS
Coordinates the response to clicking an image.
This is part of the LearningOnline Network with CAPA project
described at http://www.lon-capa.org.
=head1 GLOBAL VARIABLES
=over
=item @desklines
Each element of this array contains a line of mydesk.tab that doesn't start with
cat, prim or scnd.
It gets filled in the BEGIN block of this module.
=item %category_names
The keys of this hash are the abbreviations used in mydesk.tab in those lines that
start with cat, the values are strings representing titles.
It gets filled in the BEGIN block of this module.
=item %category_members
TODO
=item %category_positions
The keys of this hash are the abbreviations used in mydesk.tab in those lines that
start with cat, its values are position vectors (column, row).
It gets filled in the BEGIN block of this module.
=item $readdesk
Indicates that mydesk.tab has been read.
It is set to 'done' in the BEGIN block of this module.
=item @primary_menu
The elements of this array reference arrays that are made up of the components
of those lines of mydesk.tab that start with prim.
It is used by primary_menu() to generate the corresponding menu.
It gets filled in the BEGIN block of this module.
=item @secondary_menu
The elements of this array reference arrays that are made up of the components
of those lines of mydesk.tab that start with scnd.
It is used by secondary_menu() to generate the corresponding menu.
It gets filled in the BEGIN block of this module.
=back
=head1 SUBROUTINES
=over
=item prep_menuitems(\@menuitem)
This routine wraps a menuitem in proper HTML. It is used by primary_menu() and
secondary_menu().
=item primary_menu()
This routine evaluates @primary_menu and returns XHTML for the menu
that contains following links: About, Message, Roles, Help, Logout
@primary_menu is filled within the BEGIN block of this module with
entries from mydesk.tab
=item secondary_menu()
Same as primary_menu() but operates on @secondary_menu.
=item show_return_link()
=item innerregister()
This gets called in order to register a URL in the body of the document
=item clear()
=item switch()
Switch a button or create a link
Switch acts on the javascript that is executed when a button is clicked.
The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
=item secondlevel()
=item openmenu()
=item inlinemenu()
=item rawconfig()
=item utilityfunctions()
=item serverform()
=item constspaceform()
=item get_nav_status()
=item hidden_button_check()
=item roles_selector()
=item jump_to_role()
