Hi everyone, I'm writing a touchscreen device driver for the PIXCIR Tango C series (http://www.pixcir.com.cn/english/products.asp?Action=Detail&ID=95) for Linux 4 Tegra 3.1.10 (I'm using a Tegra 2 series platform).
I went through the documentation and I came up with the code you can find in this gist: https://gist.github.com/filipposironi/d9ab11e232d8cae9b8f4 . To test the touchscreen I'm using a set of X11/Qt applications and a X11/Qt/QtWebKit browser. The touchscreen works fine with Qt controls (e.g., buttons and text areas); unfortunately, the same doesn't happen with HTML controls inside the Qt/QtWebKit browser, they struggle to get the focus (sometimes they do and sometimes they don't). Everything else (scrolling with one finger, pinch and zoom, etc. works great). I initially thought the problem was inside QtWebKit; however, an eGalax touchscreen working with the device driver implemented inside drivers/hid/hid-multitouch.c behaves like a charm even with the Qt/QtWebKit browser. The evtest (http://cgit.freedesktop.org/evtest/) output I get from the two touchscreens is definitely the same. I'm wondering if there is something fundamentally wrong with my device driver (https://gist.github.com/filipposironi/d9ab11e232d8cae9b8f4) that I'm not seeing. Thanks, Filippo PS: I'm using Xorg 1.14.1 and evdev 2.7.3 with mtdev 1.1.3 support. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
