Hi Seppo, Lauri's example should work pretty much unmodified, and I did a very quick hack Sailfish example code in gitorious:
https://gitorious.org/sailfishtouchexample/sailfishtouchexample That seems to work at least on those armhf Sailfish devices that I have access to. For SDK that example does not work, since currently SDK does not report any QTouchEvents, ie. SDK only reports mouse events. But if at some point there is armhf rootfs released, then it might be useful to you. And I only tested portrait mode, one might or might not need to do some x y tweaking for mapping raw events other QML orientations. re, Jonni ________________________________________ From: devel-boun...@lists.sailfishos.org [devel-boun...@lists.sailfishos.org] on behalf of Lucien XU [sfietkonstan...@free.fr] Sent: Wednesday, March 13, 2013 10:18 PM To: devel@lists.sailfishos.org Subject: Re: [SailfishDevel] QML support of Multitouch Hello Seppo, Instead of subclassing QmlApplicationViewer, did you ever tried to just subclass a QDeclarativeView, and add the given code from your link to that subclass ? It should work. Cheers, Lucien Le mercredi 6 mars 2013 10:48:15 Seppo Tiainen a écrit : > What I have been missing most in QML is multitouch support.
