Hello Thiago, Simon, This is a good step, and will help reduce the current implementation gaps between webkit2 and chromium's engine in terms of CSS, among others.
What is the roadmap for Graphics-surface implementation (needed for WebGL) for full screen platforms like eglfs ? I have been carrying patches for this from 5.0.0, and need to understand how this will change in the new renderer. regards, Prabu -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Thursday, September 12, 2013 10:23 PM To: [email protected] Subject: Development Digest, Vol 24, Issue 44 Send Development mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://lists.qt-project.org/mailman/listinfo/development or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of Development digest..."

This also means iOS won?t be supported." So what are the plans for Android and iOS? We currently do not have QtWebkit on those platforms and support for QtWebEngine is not planned. Does that mean we won't have any WebView at all for Android and iOS or are some kind of wrappers around native widgets planned for those systems? Thanks!

Hi Lars Thanks for the link. I also see it making the news in social media very quickly. I'd like to point out that Intel announced Crosswalk two days ago and it's a Blink- & Chromium-based web runtime. That is, it overlaps quite a bit between a web engine. I spoke to Alexis and Kenneth a while ago about Crosswalk and Qt and they assured me there is a lot that can be shared. But not knowing the details, I don't know for sure, and we couldn't interact until the project was announced. They now are. So I ask: is there mutual benefit? https://crosswalk-project.org/ (not other crosswalks on the web) -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center -------------- next part -------------- A non-text attachment was scrubbed...

I am, however, still confused by both of your responses. Thiago - The qMetaTypeId documentation (http://qt-project.org/doc/qt-5.1/qtcore/qmetatype.html#qMetaTypeId) specifically states that the type registration using this function is resolved at compile-time, not run-time. Stephen - The qMetaTypeId documentation goes on to provide a code snippet where a custom type (MyStruct) is registered, so it would seem this should work for non-built-in types as well. As such, the documentation leads one to believe that qMetaTypeId can be used to register one's custom type at compile-time, as I tried to do in the code snippet in my original query. Is the documentation completely wrong or is a compile-time type registration still possible in some way? I am very interested in this, as the system I am working on would greatly benefit from this functionality.

It is as you predicted glDrwaElements. Is there any possibility to make some kind of workaround patch to make it work on emulator (I suppose it is emulator GL issue), perhabs by turning off some optimizations and so on?
