Integrate Tslib with QT



  • Hi

    In my project I am using timesys linux kernel 3.0.

    We are using the Factory for building the filesystem.

    I have enabled the tslib in the build system and i could successfully build the QT and Tslib related things like ts_calibrate,ts_test.

    i have copies ts.conf under /etc and copied ts_calibrate and ts_test under /usr/lib.

    And finally I have copied ts folder and libts-1.0.so.

    By adding below environment variables in /etc/profile

    export QT_QPA_PLATFORM=linuxfb
    export PATH=$PATH:/home:/jre/ejre1.7.0_45/bin/
    export LOG4C_RCPATH=/home/CV1/log4c
    export QT_DEBUG_PLUGINS=1
    export QT_PLUGIN_PATH=/usr/lib/qt/plugins
    export QT_QPA_FONTDIR=/usr/lib/fonts
    export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/qt/plugins/platforms

    export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0
    export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event0
    export TSLIB_FBDEVICE='/dev/fb3'
    export TSLIB_CONSOLEDEVICE=none
    export TSLIB_TSDEVICE=/dev/input/event0
    export TSLIB_CALIBFILE=/etc/pointercal
    export TSLIB_CONFFILE=/etc/ts.conf
    export TSLIB_PLUGINDIR=/usr/lib/ts
    export TSLIB_TSEVENTTYPE='INPUT'

    I could successfuly run ts_calibrate and ts_test.

    As a result of running ts_calibrate, a file named pointercal will be generated.

    And when i execute the ts_test I can see that drawing app is working perfectly.

    But concern is that When i tried to load a drawing QT application which is developed by me which is using openGL and frame buffer,the touch is not working as ts_test works.

    I could understand that my QT application is not using the pointercal file.

    Could you please help me to resolve this issue.

    How can i verify whether my test app is using the pointercal file or not?
    Am i missing something??

    Regards

  • Hi,

    May I ask you, what's in your test application?

    What events you are looking for?

    I guess, tslib, posts the touch events as mouse events to Qt. If you are processing mouse events, then we should analyze in a different way.
