Okydoky. > > WebKit2/Shared/CoreIPCSupport/DrawingAreaProxyMessageKinds.h:44 > > + TileUpdatesComplete, > > Maybe a better name can be found, as it is not clear what it complete. a current round of tile updates? Indeed. It fires when there are no more tile update requests pending. Any ideas for something better? RequestedTilesUpdated? > > WebKit2/UIProcess/API/qt/qgraphicswkview.cpp:52 > > + void _q_scaleChanged(); > > + void commitScale(); > > Why is one with _q_? and the other not? Should both be, or none be? The _q_ is Qt convention for handling the public class's signal in the private class. We could call it e.g. onScaleChanged() instead, I don't really mind. > > WebKit2/UIProcess/API/qt/qgraphicswkview.cpp:78 > > + d->page->setViewportSize(geometry().size().toSize()); > > does this make sense?

Submit, commit? or begin, end? Will change to begin/end. > This is using old API, you should be able to call sent(DrawingAreaMessage::SetSize(viewSize) I beleive The necessary code isn't generated for this class. Fixable of course, but I'd rather do that in a separate patch. > > WebKit2/UIProcess/TiledDrawingAreaProxy.cpp:125 > > +void TiledDrawingAreaProxy::didReceiveMessage(CoreIPC::Connection*, CoreIPC::MessageID messageID, CoreIPC::ArgumentDecoder* arguments) > > +{ > > + switch (messageID.get<DrawingAreaProxyMessage::Kind>()) { > > + case DrawingAreaProxyMessage::TileUpdated: { > > Can you verify it this is the way it is still done?
