Image Gestures example does not work
I built and ran the Image Gesture example that came with my Qt 5.2.1 mingw install. It doesn't respond to any of the gestures I tried: pinch, pan, or swipe. Does this example only works in some OS versions?
I am running Windows 8.1 with a touch screen (Dell XPS One 2710) and both my touchpads (Logitech T650 and Wacom Intuos Pen & Touch) don't work with it either.
Since Qt 5.3 is about to go out, can you try with it ?
Tried 5.3RC1 and it's not much better.
Only pinch and pan event are handled. Pinch always reports a scale factor of 1 so it never scales.
It also doesn't work with either of my touchpads. Only touch screen works.
Then you should have a look at the "bug report system":http://bugreports.qt-project.org to see if it's something known. If not please open a new report providing as much details as you can
Can't find anything on bugreport so filed a new one: https://bugreports.qt-project.org/browse/QTBUG-38925
How about running on Qt 4.8.5 with linux-arm platform. Does it have some special notes to make it work?
I have tried to cross compile it and run on MCU arm9, but no event come (only some event paint firstly).
More infomation, i have configured env params and can run ok with single touch.
Thank you very much.
Please don't highjack threads with unrelated questions (the only common point is the touch part)
That's a bit vague. Did you check that tslib is working correctly ? That you have access to the input device ?
I am so sorry about my mistake. I will more notice at posts later.
tslib is config to work correctly with single touch. I mean i have access to the input device.
I think it will be better to stop my question here. I will move it to suitable place.
