jenkins-bot 0eb2581b64 Merge "ve.ui.Context: Add embedding feature" 2013-05-16 18:26:39 +00:00
Trevor Parscal 55b5f30edb ve.ui.Context: Add embedding feature
Objectives:

* Make the context menu display in the top right corner of the currently
  focused inspectable node (if there is one)
* Prevent clicking on anything to do with the toolbar or popup from doing
  anything at all, ever

Bonus:

* While we are using the clever feature in jQuery's on method which allows
  passing boolean false to cancel the event - may as well do that in
  ve.ui.Dialog as well

Changes:

ve.ui.FocusableNode
* Add ability to specify the focusable element so that dimensions can be
  derived from it

ve.ce.Surface
* Add quotes to object keys

ve.ui.MediaDialog
* Change association from being MW specific to handling images in general

ve.ui.Context
* Add embedded styles for context
* Add embedded mode, which is triggered when the context is a single
  focusable node, and the node is large enough to fit the context
  reasonably

ve.ui.Dialog
* Inline mousedown handler

ve.ui.Toolbar, ve.ui.PopupWidget
* Cancel stray mousedown events

Trevor Parscal 79df2232a5 Fix for default sort key crash
The existing default sort key was being cached when the dialog was
constructed, but on the 2nd time launching it the reference was broken.
This change gets rid of the caching and always grabs a fresh copy when
we need one.

Also, the flag indicating the default sort key has changed wasn't being
reset properly.

jenkins-bot d4d8e9075d Merge "EventEmitter API cleanup" 2013-05-02 23:48:30 +00:00
Trevor Parscal 7233ea8f1b EventEmitter API cleanup
The EventEmitter API we inherited from Node.js and then bastardized was
getting awkward and cumbersome. The number of uses of ve.bind was getting
out of control, and removing events meant caching the bound method in a
property. Many of the "features" of EventEmitter wasn't even being used,
some causing overhead, others just causing bloat. This change cleans up
how EventEmitter is used throughout the codebase.

The new event emitter API includes:
* emit - identical to the previous API, no longer throws an error if you
  emit error without a handler
* once - identical to the previous API, still introduces a wrapper* on -
  compatible with the previous API but has some new features
* off - identical to removeListener in the previous API
* connect - very similar to addListenerMethods but doesn't wrap callbacks
  in closures anymore
* disconnect - new, basically the opposite of addListenerMethods

Another change that is made in this commit is mixing in rather than
inheriting from EventEmitter.

Finally, there are changes throughout the codebase anywhere
connect/disconnect could be used.

Moriel Schottlender 29f5630957 RTL fix for VE's link widget
The purpose is to flip the direction of the input inside
the link widget for RTL wikis, but flip it again to LTR
if the user inserts an external URL. This is my first VE
fix, I tried to follow conventions and avoid touching the
parent objects that are unrelated to URLs.

Ed Sanders d4eef1b879 Fix range translation for surface fragments
Remove all manual changes to SF ranges as these are not
undoable. Instead change translate range to default to
outer expand and build functionality around that behaviour
never changing.

As translate range is always outer I don't think we need to
check for start and end crossing over?

Added more undo tests to assert these selections are maintained
properly, and added the test case to 'update' for when and undo
point is overwritten.

Insert content now results in a selection over the inserted
content. Most usages were expecting this anyway and were
followed up with an adjustRange(-length,0) which is no longer
necessary.

Noticed that the link inspector case was never being triggered
as word boundary was always expanding to at least one char (mainly
for Hanzi selection). This doesn't make much sense as single
spaces get auto selected so removed this functionality.

Split collapseRange out into collapseRangeToStart and
collapseRangeToEnd as this may be required to get the old
behaviour (range moves to end after insert).

Trevor Parscal 3bcac07aab Fix ve.ui.get$$'s handling of jQuery selection
Turns out, the context property of a jQuery selection isn't always
there.

For example:

$( 'body' ).context === document
$( '<div>' ).context === undefined

Even if you later attach that div, so long as you have the old
selection around, the cached `context` property won't magically be
updated. This makes sense (although it's poorly documented in the
jQuery API) but causes issues for us, and pretty much makes the
context property useless.

Instead, we can just use the standard `ownerDocument` property,
available on all DOM elements.

This change also add support for passing in a DOM element directly, in
addition to the existing support of passing jQuery or Document objects
in.

Ed Sanders 8b09dd7650 The resurrection
By removing the transaction listeners from surface fragments we
no longer have to make sure they are always manually destroyed.

In order to retain the functionality of having fragments update
with transactions elsewhere we keep a pointer to a place in the
new complete history stack in the surface. The complete history
stack records all transactions, even undone ones.

Whenever getRange is called we replay all transactions in the
complete history (in the correct order) since the fragment was
last updated.

Also in this commit:
* Updated Format/IndentationAction to test undo(). This increases
  coverage of surface fragment behaviour.
* .range is always accessed by .getRange now, although as an
  optimisation we can use the noCopy mode when we a sure the
  returned range will not be modified.
* Added undo test to .update (previously .onTransact)

Bug: 47343

Trevor Parscal 1878c7c5a8 Allow node relocation
*.php
* Added links to new file

ve.ce.ImageNode.js
* Added relocatable node mixin
* Added $image reference to the actual img element, so if it's wrapped
  in a sub class the functionality in the parent class  doesn't break.
* Moved drag start event handling to relocatable node
* Removed drag end binding, not needed.

ve.ce.MWImageNode.js
* Moved addClass to initialization section of constructor.
* Copied 'view' data prop from image element to keep stuff working after
  the wrapping.

ve.ce.Node.css
* Switched to default (arrow) cursor for images.

ve.ce.RelocatableNode.js
* New mixing for nodes that should be relocatable
* Added implementation for drag start, which tells the surface to allow
  dragging this node.

ve.ce.Surface.js
* Added relocation support, which is used by relocatable nodes
* Split onDocumentDragDrop into onDocumentDragOver and onDocumentDrop
  which now have implementations that support relocation of nodes

ve.ui.Context.js
* Added relocation tracking to prevent context being shown while
  relocating
