The biggest change is that the navigation block has been converted to a proper YUI module.
The following are the other changes made at the same time:
* A loading icon is displayed when a branch is being loaded by AJAX.
* Fixed a bug where you could trigger multiple AJAX requests by rapidly clicking an unloaded branch.
* Fixed a bug where empty branches weren't being marked as such after a successful AJAX load.
* When docked the width of the blocks dock panel is now inspected an increased if required to try avoid horizontal scrolling.
* Removed the no longer needed inclusion of the YUI2 dom library from the navigation and settings block.
* Expandable nodes are now passed as JS data allowing the navigation JS to be initialised through block_navigation::get_required_javascript.
* AJAX is now focused around the branch in question rather than the tree in general.
* Expansion of branches is now delegated to the tree rather than being an individual event on all branches.
* Tidied up the code in general removing unneeded-unused parameters.
* Themes can now check if a region is completely docked
* Dock now delegates events to improve performance
* Dock now completely YUI3
* No longer uses YUI overlay instead has custom control
Navigation has now been re-ordered in accordance with http://docs.moodle.org/en/Development:Navigation_2.0_structure.
This has led to several changes in the way in which navigation is generated included API changes, most notably using the
navigation_nodes add method now returns the newly added node rather than the key.
At the same time the global_navigation_tree block has been renamed to navigation and settings_navigation_tree to settings.
Very big theme changes, standardold theme has been split into two themes base and standard. Base theme contains only CSS that is absolutly required (e.g. layout, white space rules, specific widths) and standard (which now looks like standardwhite) contains all the frills.
The following noteable changes have also been made:
* Plugin CSS has been pushed back into the plugin directories as styles.css files.
* Install_print_header has been corrected.
* Redundant or deprecated rules have been removed.
* Several minor class changes throughout Moodle.
* CSS is now single line rules not multiline indented.
* Installs with theme=standardold automatically switch to standard.
* body classes / id now have prefixes to make it clearer what they are and avoid conflicts.
Also worth noting:
* There is still alot of tweaking that is required to get everything looking as it is supposed to, please be patient or better yet help out.
* I am currently working on the documentation for the themes system... it will be here soon.
Also included in this patch the ability to switch the dock from the left to right side of the screen.
Altered js_object_init to deliver Y like js_init_call does now.
Several minor tweaks made to the dock and navigation as well at the same time.
