Hi,

I’m looking to find a way to get my Multi-Touch Device working with Qt (2 Finger gestures). Right now my TRS Multi-Touch is working only with Tslib (with Linuxtp and Linuxinput no success). As I understand Tslib does not support multi-touch gestures?

  • Does QWS support Multi-Touch gestures? If not what can I do in an embedded system?

I made some tests with the Qt-examples with activated qpa/Lighthouse (-platform LinuxFB). Framebuffer is working but touch not… Due to our HW does not support OpenGL we need the QWS platform.

My system: cortex-a9, Qt4.8 (non qpa/lighthouse), Tslib 1.0-106.

Thanks for your help!

Hi,

I'm not sure Ask Linaro is the best place to ask questions about Qt, though of course this is an interesting topic.

In addition, Linaro doesn't include Qt in the images that it releases (we use X for Ubuntu and the Android graphic stack), so we have no special experience with Qt.

You may get more answers on Qt Embedded groups, such as http://developer.qt.nokia.com/groups/qt_embedded. But hey, let's hope that other people here will have answers too...

Good luck,

Michael.

Hi Michael, thanks for your answer. Unfortunately on other embedded groups, especially for embedded Qt, I got no answer. We'll see and hope :)

I am very interested in this answer. I asked question lately about QT embedded w framebuffer no X.

Status update...

we actually have stopped the issue Multitouch with embedded Qt... As conclusion, following must be done: Due to the information from here , you have to add multi-touch support to tslib (see link) . With the description http://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt it should be possible to extend the Qt Mousedriver (.../src/gui/embedded/qmousetslib_qws.cpp, *.h)

Best regards Helmut
