Also, part of the change from weblib.php functions to $OUTPUT-> methods.
This is part of http://docs.moodle.org/en/Development:Theme_engines_for_Moodle%3F
This is a big change, and the result is not perfect yet. Expect some debugging output
on some pages.
The main part of these changes are that $OUTPUT->header now looks for a file
in the theme called layout.php, rather than header.html and footer.html. Also
you can have special templates for certain pages like layout-home.php. There is
fallback code for Moodle 1.9 themes, so they still work.
A few of the old arguments to print_header are no longer supported. (You get an
exception if you try to use them.) Sam H will be cleaning those up.
All the weblib functions that have been replaced with $OUTPUT-> have version in
deprecatedlib, so existing code will go on working for the foreseeable future.
That allows us to have a few sentences explanation of each question type, and is also easier to fit into a tight layout.
This commit should also fix MDL-18214 Layout screwed in Safari with long category names.
These are all to do with the combination of the $form->category, and $form->categorymoveto fields on the question editing forms since Moodle 1.9. These are now resolved to a single ->category value in question.php, which simplifies the logic for the individual question types.
MDL-15774 and MDL-12719 errors editing Cloze question
MDL-17105 problems with qustion saving logic.
MDL-18174 'Select from subcategories' option not preserved when editing a random question.
This was started and usability tested as a Finnish Summer of Code project, and then Olli did further work on it in his own time to get it in shape for inclusion in Moodle 2.0. I reviewed all the code. There are a number of minor outstanding issues that will be fixed soon. See the subtasks of MDL-17284 for a list.
The goal of these changes is to:
* help teachers new to Moodle, so when they first see the quiz editing page, they don't go "Huh! What on earth am I supposed to do here?"
* help novice Moodle users understand and learn to use some of the more advanced quiz feature;
* but, without slowing down more experienced quiz users.
Naturally, with ambitous goals like that, we won't have managed to satisy everybody, but I think this change is a big step in the right direction.
There is extensive documentation on this project at http://docs.moodle.org/en/Development:Quiz_UI_redesign.
This commit does two things:
1. Gives question types he opion to use formslib for their editing forms, instead of the old mechanism.
2. Converts the truefalse question type to formslib.
