1.設置qt運行的環境變量：
#!/bin/sh
#configure for tslib
export TSLIB_ROOT=/opt/tslib
export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts
export TSLIB_CONSOLEDEVICE=/dev/tty
export TSLIB_FBDEVICE=/dev/fb0
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$TSLIB_ROOT/lib
#configure for qt
export QTDIR=/usr/local/Trolltech/QtEmbedded-4.6.2-arm
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=/opt/qt4/bin:$PATH
export QWS_MOUSE_PROTO=tslib:/dev/input/event0
配置後，QT應用程序即可支持觸摸屏
