Comment 1 for bug 1105371

I'll keep this up to date on what I find, but since I didn't mention in the description: I think this one is going to be harder than it looks.

First, probably worth mentioning that Orca also does not mention the other image inside the Install column. Right now, when I select a row in the updates list, it says "Image, System Settings, Expanded - three Items, 12.5 MB". If it was reading all of the cells, it would say something like "Image, Checkbox - ticked, Image, System Settings, Expanded - three Items, 12.5 MB". If all was right in the world, it would skip both of those images and say (at least) "Checkbox - ticked, System Settings, Expanded - three Items, 12.5 MB". If I change the order of those cells inside the Install column (and use Gtk.CellAreaBox instead of CellAreaPackage), Orca _still_ reads the label cell. The screen reader does mention the toggle cell correctly if it is in its own column, but that is quite unattractive.

I poked at Software Updater with Accerciser and it looks like the stuff inside the Install column all reaches it correctly. The toggle cell inside our GtkCellArea looks exactly like a toggle cell in its own column, except nested a little deeper. I'm hoping that is helpful for someone who knows anything about accessibility. (Eg: Not me). :)
