Problems with Multitouch on Debian Wheezy
-
Hi all,
I have a debian wheezy system with Qt 5.5 and an USB Multitouch screen.
- mtdev-test works and shows the correct number of recognized fingers (up to 10)
- export QT_XCB_DEBUG_XINPUT_DEVICES=1 displays the following:
# some other devices.... qt.qpa.input.devices: input device 3M 3M MicroTouch USB controller qt.qpa.input.devices: has 5 buttons qt.qpa.input.devices: has valuator "Abs X" recognized? true qt.qpa.input.devices: has valuator "Abs Y" recognized? true qt.qpa.input.devices: has valuator "Abs MT Position X" recognized? true qt.qpa.input.devices: has valuator "Abs MT Position Y" recognized? true qt.qpa.input.devices: has valuator "" recognized? false qt.qpa.input.devices: has valuator "" recognized? false qt.qpa.input.devices: it's a scrolling device
Well, okay... a scrolling device!?
- export QT_LOGGING_RULES=qt.qpa.input=true and touching on the screen displays:
qt.qpa.input: XI2 mouse motion 939,690, time 3870757 qt.qpa.input: XI2 mouse motion 976,671, time 3870778 qt.qpa.input: XI2 mouse motion 1025,648, time 3870778 qt.qpa.input: XI2 mouse motion 1084,613, time 3870781 qt.qpa.input: XI2 mouse motion 1151,576, time 3870789 qt.qpa.input: XI2 mouse motion 1220,551, time 3870797
So... Does anybody has an idea how to tell Qt that this is a multitouch device?
Setting QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS to the appropriate event didn't helped.Thank you very much in advance!!

Hi,
I think you should bring this question to the interest mailing list. You'll find there Qt's developers/maintainers (this forum is more user oriented)
