[webkit-dev] Focus traversal question

[Artem Ananiev]

To embed an instance of WebKit component into the application, it should be a 
good 'citizen' of focus traversal chain. For instance, when focus is in the 
component previous to WebKit and user presses TAB key, focus should be moved to 
the first focusable component on the WebKit page; while focus is on the last 
focusable component on the page and TAB is pressed, focus should be traversed 
out of WebKit.

Sometimes, for example, when I press mouse on any text field on the page, WebKit 
requests focus from the platform (Widget::setFocus() method). But I don't see 
any platform callbacks when focus should be traversed out of WebKit. One more 
question is about first and last focusable components on the page, how can I 
find them? It is required to implement both forward and reverse traversal chains.

Thanks,

Artem
