Revision 1.4: download - view: text, annotated - select for diffs
Fri Feb 14 19:35:55 2003 UTC (22 years, 3 months ago) by www
Branches: MAIN
CVS tags: HEAD
A lot of things happened here:

* everything menu-related was moved out of lonxml, and into lonmenu
* thus, function calls to registerurl, loadevents and unloadevents modified
* fixed lontex.pm, which actually did not call the right routines
* put in calls to lonmenu::menubuttons, which is supposed to insert buttons
  after the body tag in "textual mode" - this function and registerurl will
  be unified (buttons either in Remote or on top of page)
