To clarify Sverrir and my intent;
PDF (or EMF as it's currently done on the windows port of Chromium)
snapshot is fine for a static print preview but useless for a
dynamic one. We'd prefer to have something interactive. If a user
changes the layout or the page setup, the print preview is
immediately updated. To do that, we need to make the print preview
application modal (because of javascript interactions) and I think
it defeats the purpose of tabbed browsing.
(Please correct me if I'm mistaken)
The goal is to make the print preview in its own tab and not modal
anymore. So the idea is to duplicate the Document/Frame along with
RenderView and all their children into a new WebView, disable their
javascript, timers and url request ability. This copy would be used
to regenerate the print preview/printed document.
That's quite a daunting task, we'd like to know if we missed
something obvious (or already existing!) and if not, if anyone else
would like to see the same feature.
I don't think you actually have to clone the render tree explicitly.
You could use DOM operations to clone the DOM and let new renderers
get constructed by that process.
