[webkit-qt] Roadmap Clarifications: QML WebView ?

Hi there,

Using QGraphicsWebView is fine and you can always make a QML class out
of it, if needed.

I do not know what kind of animations you refer to, CSS3? Are you
using accelerated compositing?

For effective scrolling/panning you will need to use the tiling
feature and the resizesToContents feature. With that you should see
improved panning performance, but it might require a bit more work...
look at the QtTestBrowser in WebKit... you will find it in the Tools
subdirectory. It is a good source of ideas on how to make this work.

In order to get a real non-blocking experience you will need to run
webkit in another thread or process. This in non-trivial and part of
our WebKit2 strategy. This meaning that our current WebKit1 port is
mostly feature complete and most mobile related performance work will
probably to into our WebKit2 port.

If you are interested in what this means you can have a look at my
FOSDEM presentation (there are videos somewhere as well)

If you are a brave soul, you might even be able to find out webkit2
port on gitorious :-) but you probably want to hold off a bit on using
