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/platformsexport 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.
