Toolbars and toolbar buttons are currently implemented using XUL markup. We want to change it and make sure the UI is generated using HTML elements. In this case it's probably better to replace markup in-place. Introducing React components might be done later (in a follow up). There are following toolbars related to this report: - The main Toolbox toolbar (tabbar, but contains registered command buttons) - Main Inspector panel toolbar (with search box) - Rules side panel toolbar - Computed side panel toolbar - Animation side panel toolbar Honza

So, first I had to solve the drop down menu for selecting iframes. I used API implemented in bug 1257613. Brian, what do you think? Further patch (converting XUL -> HTML) will yet follow. Honza

Here the the second part. - Toolbox buttons are HTML - Toolbox doc & close buttons are also HTML - The Inspector buttons & toolbar are HTML Honza

Forgot to note, there is one known problem. The focus management works differently int HTML and XUL and I am not sure how to fix this. This test shows that (it fails). devtools/client/framework/test/browser_toolbox_keyboard_navigation.js I am going to file a follow up for it and we should discuss how important this is (could be rather harder to fix). Honza

some of the UI differences I see with the patches applied

I noticed this causes the breadcrumbs layout to get messed up when overflowing / inspecting large DOM. You can see this if you inspect into a page like cnn.com, or if you inspect the toolbox with the Browser Toolbox.

You can see this if you inspect into a > page like cnn.com, or if you inspect the toolbox with the Browser Toolbox. This could be worked around by setting display: -moz-box on #inspector-breadcrumbs-toolbar until the breadcrumbs converted, but this also causes layout issues on all the tools (see webconsole toolbar, debugger toolbar, etc). I'm thinking the 'flex' layout should be opt-in for now unless if we can tackle all of the layout issues here.

Okay, I did it specifically for the Inspector toolbar. Honza

Ah, if you are testing on OSX then that test is meant to fail: https://dxr.mozilla.org/mozilla-central/source/devtools/client/framework/test/browser.ini#46.

Fixing existing tests for the iframe-picker. The internal structure of the menu should not be used in the tests (it'll change to HTML at some point) so, instead of clicking on individual menu-itemes I am using toolbox.onSelectFrame() to switch frame-context. Honza

Honza, the two code patches need rebasing on top of fx-team

Honza, could you please make a try push and request Helen to do a UX review of the changes to make sure we aren't missing anything?

Note that I still get conflicts with toolbox.js and toolbox.xul with the latest patches.

Just a couple of CSS lines changed to fix the side bar toggle button and vertical centering of text in the Search box in Inspector panel. Honza

Agreed, I changed the selector and used #inspector-searchbox. See my patch Honza

Tim, see the screenshot, there are two problems: 1) The toggle button is inverted (this is now properly fixed) 2) The text in the search box isn't v-centered (fixed by new rule applied directly on #inspector-searchbox Honza

Yes, I am aware of this. I didn't want to touch the internals of the Menu API. These are still using XUL internally, which is a workaround and it should change to HTML. But, I agree we should test this somehow. We could have test API that are wrapping the fact that XUL is still used inside.

We could > have test API that are wrapping the fact that XUL is still used inside. I don't see why the fact that we are using XUL behind the scene changes anything? We just miss the tests being written and/or a naive API on menus to check their state. Something like: menu.onshow = function () { is(menu.items.count, 10); is(menu.items[0].label, "foo"); } > I filled a follow up for this and we can discuss how to do it properly: bug > 1274558 > Is that ok to do it as a follow up so, we can land this? It is if bug 1274558 is a immediate followup where you are going to modify tests from attachment 8754348 [details] [diff] [review] to assert menus instead of the toolbox maps. It is not if that ends up being triaged as a P4-enhancement that may not be done. It is not if that's only going to add test against menu codebase only. The point if about testing menu behavior on real world usages like toolbox tests.

In theory the fact that we are using XUL behind the scenes could make initial migration of the test easier since the XUL elements that are being checked will still exist (although only when the menu is opened)

Rebase Honza

(In reply to Alexandre Poirot [:ochameau] from comment #59) > The point if about testing menu behavior on real world usages like toolbox > tests. Alright, agreed, here is updated version. Tests are now doing somethings like as follows: // Showing the context menu and wait till it's ready on the screen. // The test isn't simulating clicking since it needs reference to // the Menu object. This should be ok since `showFramesMenu` is the // direct click handler. let menu = toolbox.showFramesMenu(); yield once(menu, "open"); // Verifying that the menu is properly populated. let frames = menu.menuitems; is(frames.length, 2, "We have both frames in the list"); The test is accessing the internal 'menuitems' structure, not the XUL structure so, when the XUL->HTML transformation happens the test won't break. Also, testing the internal XUL (or later HTML) structure should be done by tests related to the Menu itself. Honza

I tested this bug on - 50.0a1 (2016-06-09) - 49.0a2 (2016-06-09), using - Windows 10 x64 - Ubuntu 14.04 x86 - Mac OS X 10.11. The overall toolbars and buttons state seems to be the expected one and also, there is no misbehavior between the last and the present implementation. There is one exception: on Ubuntu 14.04 x86 and on Mac OS X 10.11, Rules, Computed, Box Model and Animations side panel buttons have a "breadcrumbs" border when clicked. This issue is not reproducing on 48.0a1 (2016-04-21).
