For inline editing, I need to be able to put a textbox (focusable widget) inside a XUL popup. I mentioned this to pink and hyatt, and they laughed for at least five minutes. Hyatt thinks there are some tremendous focus issues to solve here, and since he's the standard scapegoat for them, I'm giving this bug to him! =D Dave, I'll be checking in a test case for this at the start of .9.5.

See also bug 94713.

Akin to Hixie-P1, I'm marking this bug Ben-P1. No dinner, but whoever fixes this bug gets US$20.

I really believe that using a stack to do inline editing is a much safer and simpler approach to take to implement the feature.

Note that this bug still needs to be fixed before anyone can use resizable popups seriously, for instance, rginda wants to use floating palettes for venkman, etc. I'll pay $20 for $20 worth of serious investigation, even if at the end of that it is still too hard. ;)

Well, we should distinguish between your approach of trying to use a piece of a sub-document in a floating window, and a floating window that could load an entire document, e.g., a sort of floating iframe. What makes this really difficult is the fact that the DOM window's widget does not enclose the focused content (the popup does).

WFM? Firefox 3 uses <panel>s with focusable elements all over the place. There are some issues (bug 395670) but it basically works.
