- added class format_base as the base for all course formats
- added class format_site for the pseudo-format 'site' used for displaying activities on the front page
- added class format_legacy that overrides format_base functions with calling old-style 'callback_xxx' functions
- replaced all usage of 'callback_xxx' functions with format_base methods
- made arguments of get_section_name(), get_course_url() more flexible
- deprecated function get_generic_section_name(), it's contents is moved to format_base
- global_navigation::format_display_course_content() is removed, plugins can supress the sections navigations using extend_course_navigation()
This commit coverts everything in the codebase to use the new
users_order_by_sql function when sorting lists of users. More details in
the bug.
Note that this does not change places where users are displayed in a
sortable table, and the sort order comes from the table.
Use YUI event delegation to handle events in course section "toolboxes" (visibility and highlight toggles) rather than attaching event handlers to each individual button we care about. Also remove the (now unused) replace_button() function.
Use YUI event delegation to handle events in course resource "toolboxes" (sets of editing icons) rather than attaching event handlers to each individual button we care about. Don't waste time setting the CSS cursor to what it already is, use .all() rather than replace_button() if we just need the node.
Section toolboxes could probably also be done this way to some extent, but the payoff may not be worth the effort - they're so minimal that they don't tend to cause issues.
Use YUI's DragDrop delegates for course dragdrop, rather than initialising a Drag object for each individual section and each individual activity/resource. Also, clone a single drag handle for activities/resources, rather than repeatedly creating a whole new one with the same parameters for each activity/resource.
Turns out this change was just wrong, we shouldn't be allowing linking
to unaavilable sections. Just show the availability information on the
'index page'
This reverts commit 87a31bb5d8.
