Moved setting the aria visiblity of the dialogues from the show
and hide functions into the visibility change handler to stop
multiple calls.
Also made the visibility checker just continue to buffer the elements
it hides, rather than clearning them, on multiple calls.
The table editor will now set the backgorund colour on the
table in Firefox version 34 and below.
Also expanded the dialogue slightly because the colour choices
were wrapping and I added some styling to put a gap in for the
metric markers for border width and table width.
There was a previous change to the CSS (7px -> 3px) to make things
look prettier, which acutally broke the grading by a few pixes.
I fixed this by:
* Changing the offset of the cross hairs back to the correct value,
and adding a comment to point out the imporance of not changing
that CSS.
* Achieved the nice layout of the label relative to the cross-hairs
in a different way.
* Added a similar clafirying comment in the JavaScript.
* Improved how the grid on the editing form is aligned with the
background image.
* Added rounding to the grading code, to cope better now that
browsers do sub-pixel positioning.
Fixed the issue where the file path select box goes beyond the
container with very long folder names. Instead of setting to
"width: auto", I set it the select box's "width: 100%" so that it will
just fill up its container's width.
Fixed the issue where markups are being shown on file aliases.
Quickly navigating via the keyboard to an autocomplete
element and hitting down would result in the selections
being displayed and then quickly removed. This has now
been fixed.
* Removed the "No borders" option from general borders setting
since it's a style choice.
* Added inherit, initial and unset as border style options.
* Made the border settings disabled if "Theme default" is selected.
* Changed the transparent colour to be "Theme default" which means
apply no colour at all.
Norfolk Island's standard time (NFT) was on UTC+11:30 until 4 October
2015, when it was changed to UTC+11:00. So it's not suitable for 11.5
bad mapping replacement anymore.
It seems that there isn't any other location using such 11.5 timezone
so completely getting rid of it for conversions.
Due to an incorrect condition, the activity results block would
incorrectly identify some blocks as not being gradeable.
This meant that edit form could not determine what activity the block
was added to. This commit fixes the condition, allowing the current
block to be determined correctly
With PHP bug #70322 fixed, ZipArchive::close() did start returning false
and throwing PHP Warnings with recent PHP versions (5.6.14 and up).
Previously (5.6.13 verified) it was returning true, and false in older
versions (5.4.x verified).
This change does silent the 2 "hacky" calls to close() that we perform
in core leaving the 3rd one (used for files having files) unmodified.
A new unit test has been created to cover the close() behavior, ideally
supporting both old and new PHP versions without harcoding any PHP
version.
Note that we don't use to rely much on results coming from close(), and
that's a good thing given the buggy behavior commented above. This just
keeps empty zips working like they were before.
Fixes 3 problems with deselecting items in an autocomplete field:
1. Keep track of whether items were in the offical suggestion list, or are newly created
tags and remove the "newly created tags" from the suggestion list when they are
deselected
2. Change the aria-role for the selected items list when items cannot be deselected (and
do not treat it like a multiselect list).
3. When leaving and returning focus to the selected items list, remember the last
active-descendant.
