A big stopper for this was apparently the highcontrast themes, where the close button in the corner hit target is pretty small apparently.Would something like this be doable? http://andreasn.se/diverse/temp/hc.png
I think it would depend upon the window manager. I'm not sure what metacity provides for these. Peter would probably know.
I'm pretty sure the main accessibility concern was feedback from screenreader users, who preferred the safety of an explicit Close button in the main part of instant apply windows-- i.e. one that they could Tab to, and that a screenreader would announce. IIRC, there never used to be any way for screenreader users to tell if there was a close button in the title bar or not, without pressing Ctrl-W or Alt-F4 and listening to what happened, which is obviously an unsatisfactory experience. I don't know off-hand if this situation has improved with Orca.
Orca certainly doesn't read the decorations of the window manager, and I'm not sure it can get access to them. So, having something people can tab to would still be useful.
But...before speaking in generalities, do you have specific dialogs we could take a look at? I want to make sure I understand the problem better.
Thanks! Will
