[SailfishDevel] QML support of Multitouch

[Jonni Rainisto]

Hi,

Yes, orientation support is not included in Alpha SDK. We hope to include it in the future.

In addtition to generating touch events (multi or single), it seems it is not possible to change the device orientation in the SDK's Sailfish OS Emulator either. Is this true or is there a way to test switching between portrait and landscape orientations?

Still, being able generate touch events in the next update of QtCreator's Sailfish OS Emulator would surely be welcomed by many...

Hi Lucien and Jonni,

Thanks for your help guys. I appreciate very much having your advice and a working framework which I can use as a starting point while porting my app to Sailfish OS.

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.

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
