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 registerurl() This gets called in the header section =item innerregister() This gets called in order to register a URL, both with the Remote and in the body of the document =item loadevents() =item unloadevents() =item startupremote() =item setflags() =item maincall() =item load_remote_msg() =item get_menu_name() =item reopenmenu() =item open() Open the menu =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 close() =item footer() =item utilityfunctions() =item serverform() =item constspaceform() =item get_nav_status() =item hidden_button_check() =item roles_selector() =item jump_to_role() =back =cut package Apache::lonmenu; use strict; use Apache::lonnet; use Apache::lonhtmlcommon(); use Apache::loncommon(); use Apache::lonenc(); use Apache::lonlocal; use LONCAPA qw(:DEFAULT :match); use HTML::Entities(); use vars qw(@desklines %category_names %category_members %category_positions $readdesk @primary_menu @secondary_menu); my @inlineremote; sub prep_menuitem { my ($menuitem) = @_; return '' unless(ref($menuitem) eq 'ARRAY'); my $link; if ($$menuitem[1]) { # graphical Link $link = "<img class=\"LC_noBorder\"" .
