454959 - Scrollbar in Mac toolbar customization panel no longer scrolls content

Status: VERIFIED FIXED

(Core :: Web Painting, defect, P1)

Description

[Phil Ringnalda (:philor)]

STR:

1. In a fresh clean profile, in a Mac Firefox or Thunderbird from 2008-09-06 or later, right click an empty part of the toolbar, select Customize...
2. Drag something off the toolbar (the Home button is a good choice to trash) and drop it in the panel so you'll get a vertical scrollbar.
3. Try to scroll, with a two-finger drag, or dragging the thumb, or clicking in the well, or clicking the arrow buttons. The scrollbar thumb will move, but the content stays still.

It wasn't going to be my first choice, but according to hg bisect, "The first bad revision is: changeset: 18882:5b69c1cd5976 [...] Bug 442291."

This appears to be OS-X-only:  With today's mozilla-central nightly,
it happens on OS X but not on Windows or Linux.

On Windows and Linux you don't need to drag anything off the toolbar
to test this -- if the Customize Toolbar dialog doesn't have a
scrollbar, you can resize it to give it one.

Adding status whiteboard so the Thunderbird 3 folks can track core bugs we need.

Making a random guess at a better component, since even though the regressing bug was in Gfx: Thebes, the patch was all in view/. Being Mac-only doesn't necessarily make it Mac-code-only, since the other platforms use a dialog for customization, and Mac uses a <panel>. Nudging up the severity too, since even though a workaround exists (drag a visible item, drop it on the toolbar, then drag it back to the panel, it goes to the end of the list, cycling hidden things into view), it ain't obvious.

This basically ruins toolbar customisation, blocks.

Oddly While scrolling the mouse slowly does nothing if I make a sudden jump with the wheel I can still scroll the content.

roc: any ideas what might be causing this?

After scrolling down, even if it appears that the contents didn't scroll, you can drag the correct buttons (the ones that would've shown up) onto the toolbar.

Not really

Apparently the UpdateView(this, NS_VMREFRESH_DEFERRED) calls are not doing anything so the pane is not repainted. I've no idea why. The frame positions *are* being updated, because if you force a repaint by other means it paints correctly.

Hmm, the sheet's RootViewManager is the view manager for the outer chrome document. That's Not Good.

OK, I see that on Mac, the toolbar customization dialog is implemented as an iframe inside a popup <panel>. That's crazy.

Attachment: fix

This fixes it. We're invalidating the root of the root view manager, which isn't working since we're in a floating-view situation. We don't realize we're in a floating-view situation since floating-ness doesn't propagate across view manager boundaries. We still find the correct display-root though, so let's just use that.

r+sr=bzbarsky.  I wish we could write tests for this stuff.  :(

So, this is marked blocking1.9.1+ and a P1.  Since it's also not targeted at b2 milestone, I want to make sure we're intentionally saying that we do *not* need a beta for this.  

So, does this require a beta vector?

I don't think so.

Landed on mozilla-central (and thus also on mozilla-1.9.1):

I can confirm same problem here. (Running Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b2) Gecko/20081201 Firefox/3.1b2 ID:20081201061100).

Customize tool bar window doesn't scroll the content; however, if you click on the scrollbar, it does move...)
