We want to display an accessible object's name and role information in the info-bar when highlighted. This will serve as a starting point for what sorts of information can be shown as part the accessible highlighter. See attached screenshot for an example.

Comment on attachment 8991082 [details] Bug 1473030 - Show accessible object's name and role information with the info-bar highlighter. https://reviewboard.mozilla.org/r/256082/#review263402 Good work! See comments, mostly small improvements. One issue I found: when using Browser Toolbox and hovering over accessible objects in the tree that do not have valid bounds the infobar still shows in the top left corner of the window. ::: devtools/server/actors/accessibility.js:394 (Diff revision 1) > + this.onHighlighterEvent = this.onHighlighterEvent.bind(this); > > this.highlighter = CustomHighlighterActor(this, isXUL(this.rootWin) ? > "XULWindowAccessibleHighlighter" : "AccessibleHighlighter"); > + > + this.highlighter.on("highlighter-event", this.onHighlighterEvent); OK, I think walker managing highlighter is the way to go since we are emitting events on an actor that is not transferred over the wire to the client. after highlighter is initalized, you should call ``` this.manage(this.highlighter); ``` which adds the highglihger actor to its pool of actors and assigns the actorID ::: devtools/server/actors/accessibility.js:447 (Diff revision 1) > destroy() { > Actor.prototype.destroy.call(this); > > this.reset(); > > + this.highlighter.removeEventListener("highlighter-event", this.onHighlighterEvent); removeEventListener -> off ::: devtools/server/actors/accessibility.js:448 (Diff revision 1) > Actor.prototype.destroy.call(this); > > this.reset(); > > + this.highlighter.removeEventListener("highlighter-event", this.onHighlighterEvent); > this.highlighter.destroy(); Since we now manage the highlighter (it's in walker's pool of actors), it will be destroyed when walker actor is destroyed. We do not need to call this.highlighter.destroy() any more here. Also, double check if we successfully remove the event listener even after the the highligher's destroy method was called. ::: devtools/server/actors/highlighters/accessible.js:41 (Diff revision 1) > * height of the the accessible object > * - {Number} duration > * Duration of time that the highlighter should be shown. > + * - {String | null} name > + * name of the the accessible object > + * - {String | null} role Can't be null. ::: devtools/server/actors/highlighters/accessible.js:45 (Diff revision 1) > + * name of the the accessible object > + * - {String | null} role > + * role of the the accessible object > * > * Structure: > * <div class="highlighter-container"> It makes sense for now to stick aria-hidden on the top level highlighter-container and remove role presentation, and aria-hidden from anywhere else ::: devtools/server/actors/highlighters/accessible.js:129 (Diff revision 1) > prefix: this.ID_CLASS_PREFIX > }); > > + // Build the accessible's infobar markup > + const accessibleInfobarContainer = createNode(this.win, { > + parent: container, In the function doc, the parent of the infobar container is root, instead of highlighter-container. ::: devtools/server/actors/highlighters/accessible.js:246 (Diff revision 1) > > if (this._updateAccessibleBounds()) { > this._showAccessibleBounds(); > + > + // Show accessible's infobar > + this._showAccessibleInfobar(); Wouldn't we want to first update the inforbar and then show it? ::: devtools/server/actors/highlighters/accessible.js:297 (Diff revision 1) > + > + /** > + * Hide the accessible infobar information content. > + */ > + _hideAccessibleContent() { > + this.getElement("infobar-name").setAttribute("hidden", "true"); Not entirely sure why this is necessary.

Also see box model how infobar is moved when scroll position changes. I think this is relevant in our case here too. ::: devtools/server/actors/highlighters/accessible.js:390 (Diff revision 1) > + > + /** > + * Show the accessible's name message. > + */ > + showAccessibleNameInfo() { > + const Check = new AccessibleChecker(this.options); nit: Check should not be capitalised. ::: devtools/server/actors/highlighters/accessible.js:391 (Diff revision 1) > + /** > + * Show the accessible's name message. > + */ > + showAccessibleNameInfo() { > + const Check = new AccessibleChecker(this.options); > + const { warning, message: nameMessage } = Check.evaluateAccessibleName(); Is there a reason to reassign message to nameMessage?

I think we discussed some of these accessible objects probably not having a "aria-hidden: true" attribute on them and only the "hidden" property, which can be an accessibility concern depending on the role of the object. If this is the case, should we flag this with the info-bar? Or just hide the info-bar for now until we address it in another patch? > OK, I think walker managing highlighter is the way to go since we are emitting events on an actor that is not transferred over the wire to the client. > > after highlighter is initalized, you should call > ``` > this.manage(this.highlighter); > ``` > which adds the highglihger actor to its pool of actors and assigns the actorID Sounds good, I will make sure to mention this in Bug 1474391 - Accessible highlighter does not emit "highlighter-event". > Wouldn't we want to first update the inforbar and then show it? `this._showAccessibleInfobar` removes the "hidden" attribute to the info-bar node, which makes its computed style properties available as a result. When `this._updateAccessibleInfobar` is called the `moveInfobar` needs these computed style properties to properly position the info-bar. Trying to update first causes the container to be positioned incorrectly > Not entirely sure why this is necessary. I'd expect we can get away with just having _hideAccessibleContent and _showAccessibleInfobar We would need `_hideAccessibleInfobar` since it hides the infobar container when the accessible is unhighlighted. I think for now we can remove `_hideAccessibleContent` since the infobar name would be already hidden by `_hideAccessibleInfobar`

I'll add comments here instead of inline so they are all in one place: * Nit: lets just name it Inforbar and the other one XULWindowInfobar. * From what I can tell a common api between the two infobars and the two highlighters are the following methods of the inforbar: buildMarkup, show, hide, update (move should really be done in update). * To be consistent lets: * Create infobar component at the same time we create highlighter. * Destroy(set to null) the infobar component when we destroy highlighter. * Only pass the things we need to the infobar in its constructor (root can just be passed to buildMarkup method, win and bounds can be passed to move). I think infobar doesn't really need neither highlighter nor root in the contstructor. buildMarkup method can recieve both root and createNode method which highlighter passes to it and is a wrapper around the original createNode that already sets the prefix, and has the window. * I don't think you need setContentOn (it doesn't seem to change when you override it in xul infobar either). You can just do it all in updateName and updateRole directly * XUL does not need to keep track of any of the infobar elements. * _updateAccessibleInfobar methods are not needed. You can just call infobar.update in their place. * _updateAccessibleInfobar should move as show into infobar component * _hideAccessibleInfobar should move as hide into infobar component. I think that's mostly it. ::: devtools/server/actors/highlighters.css:650 (Diff revision 3) > opacity: 0.6; > fill: #6a5acd; > } > + > +:-moz-native-anonymous .accessible-infobar-name { > + color:hsl(210, 30%, 85%); move color:hsl(210, 30%, 85%) into a variable in the beginning of the file (along with other ones) since this value is used in more places than just our inforbar. ::: devtools/server/tests/browser/browser.ini:33 (Diff revision 3) > storage-helpers.js > !/devtools/client/shared/test/shared-head.js > !/devtools/client/shared/test/telemetry-test-helpers.js > !/devtools/server/tests/mochitest/hello-actor.js > > +[browser_accessibility_highlighter_infobar.js] This is a good "integration" test. That we get things as expected on walker event. Now that we have a component on its own (infobar) we should also add a test suite for it as well (sorry to pile more work on :) ).

We don't really test much by checking markup structure. We should really just have tests for visibibility (default, after show, after hide) and text contnet of role and name.
