Why does QtQuick does not have TouchArea (like MouseArea) ?
-
Thanks.
Did you try List dragging and buttons ? -
Yes. I use GridView for that, it inherits Flickable, so that solves dragging problem. As items for it, I use just rectangles with MouseAreas inside them (one MouseArea per every button).
There were some bugs there, now I think about it, but I think it had more to do with my (at that time) sloppy coding.
-
On what HW did you test it (CPU's, RAM, clock speed, openGL) ?
-
Samsung Galaxy S2 (dualcore ARM 1.2GHz, 1GB RAM), both on Android 2.3 and 4.0.4 (CyanogenMod). I don't remember if OpenGL support was available at that time (half a year ago).
Currently I have ported my project to Qt5, which is not yet available on droid, so I don't have up-to-date news.

Does QT 5 improved your QML apps performance ?
-
Performance was good anyway, so I've seen no dramatic improvement because there was nothing to improve on ;) I did not run any benchmarks, though.
Nokia did some tests 1,5 years ago and it was, IIRC, about 200% faster. A lot has been done since then, so it might be even faster now (or not).
I did the move because I wanted to test some new features early (new particle system, 'var' properties, V8 engine, etc.). The project I am working on is an after-work hobby anyway, so I can do that easily :)
-
Was the touch performance were better with pen (stylus) than with finger touch ?
-
I've used my fingers only, no stylus.

Thanks !

Cheers. Hope it helped.
