tslib or input direct

picosoft

I'm using tslib, QT5.8 on the Raspberry3 board.
Touch is the eGalaxy on usb.

My env is,
export TSDIR=/opt/tslib
export TSLIB=/opt/tslib/lib
export TSLIB_CONFFILE=$TSDIR/etc/ts.conf
export TSLIB_CALIBFILE=$TSDIR/etc/pointercal
export TSLIB_PLUGINDIR=$TSDIR/lib/ts
export TSLIB_TSDEVICE=/dev/input/event1
export PATH=$TSDIR/bin:$PATH
export LD_LIBRARY_PATH=$TSLIB:$LD_LIBRARY_PATH
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0

export QT_QPA_PLATFORM=linuxfb:size=1280x1024
export QT_QPA_FB_HIDECURSOR=0
export QT_QPA_EGLFS_DISABLE_INPUT=1
export QT_QPA_EGLFS_NO_LIBINPUT=1

export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event1

export QTDIR=/opt/QT580
export QTLIB=$QTDIR/lib
export QTINC=$QTDIR/include
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTLIB:$LD_LIBRARY_PATH

But, QT and Application seems to using direct input.(not using tslib)

Debug information is

I want to use the tslib, no using the evdev input direct.
Please, let me know HOW.
Thanks in advance.

I assigned the tslib to input my application, but QT input data without using tslib

So, please let me know that QT gets touch data from tslib not evdev direct.

Hi and welcome to devnet,

From your console log, the tslib and linuxfb plugins are loaded.

Hi, Mr. SGaist, thanks for your prompt answer.
Yes, tslib and linuxfb plugins are loaded, but, the touch input data is from evdev, not from tslib. I don't know why.
The ts_read was called from QT, and the right touch data was given to QT, but if print, coordinate data was from input data, not tslib.
I think the raw data is calculated as (dpi) X (raw data) / (max data).
So, I want to use the tslib.

Maybe, this problem seems to be Linux input setting.

SGaist

How exactly did you determine that ?
