Qt4.7 arm-linux移植，屏幕旋转

下载 qt-everywhere-opensource-src-4.7.4.tar.gz

解压至arm Qt目录，与PC版，x86版分开

配置脚本： myconfig.sh

#!/bin/bash

#qt-gfx-transformed 选项实现窗口旋转

前提编译好ts库

交叉编译器4.43 编译过程未见出错。

设置开发板相应环境变量，比如写入profile或 /usr/etc/rc.local,并在/etc/init.d/rcS中source一下

export QWS_DISPLAY=LinuxFB:mmWidth320:mmHeight480:0 纵向使用屏幕

export QWS_SIZE=320x480

export QWS_DISPLAY=Transformed:Rot270 窗体旋转

export QT_QWS_FONTDIR=/usr/local/Trolltech/QtEmbedded-4.7.0/lib/fonts

export QWS_MOUSE_PROTO=Tslib:/dev/input/event0

export TSLIB_CONSOLEDEVICE=none

export TSLIB_FBDEVICE=/dev/fb0

export TSLIB_TSDEVICE=/dev/input/event0

用-display参数来代替以上export的变量】

假如将运行的程序是qtdemo

qtdemo -qws -display "LinuxFB:mmWidth200:mmHeight100:0"

qtdemo -qws -display "Transformed:Rot90"

qtdemo -qws -display"Transformed:Rot90:LinuxFB:mmWidth200:mmHeight100:0"

上电自动启动：在rc.local中调用相应程序即可
