The hints I get from this e-mail is that the issues described aren't really UI related at all (as long as they didn't implement the fetching of e-mails and akonadi/IMAP in JS, which I highly doubt). > Sorry, but I honestly tried to find some info and screenshots googling "KMail > Touch", and the first 20 or so hits link to issues about performance. My first link was http://be-jo.net/2011/09/kontact-touch/ (however, might be because google defaults to German for me). > Maybe that little mail client is already too complex for QML, even in > combination with C++? I don't want to know what happens when it comes to > *real* desktop applications with regards to to resources usage and > performance... Sorry, but this is spreading FUD. It's true that QML builds on top of the JavaScript language. But that doesn't mean that you can blame the JavaScript interpreter for everything :) E.g. object creation doesn't involve JavaScript, simple bindings are optimized away too ... > p.s.

Looking forward to some hard evidence :) Regards Kai _______________________________________________ Qt5-feedback mailing list Qt5-feedback@qt.nokia.com http://lists.qt.nokia.com/mailman/listinfo/qt5-feedback
