运行本例时请先把.qti18nrc靠到用户根目录下
启动chinput然后编译运行
使用经过i18n patch 的QT库, 可以不使用中文平台即可以显示/输入
中文. 在本例中, 你需要把.qti18nrc 拷贝到用户目录下方可使用,
在TurboLinux中, 本文件在建立用户时自动产生.
.qti18nrc
Makefile
Makefile.in
qwerty.h
main.cpp
qwerty.cpp
qwerty.pro
请注意: 缺省的qt补丁不认识Chinput的XIM输入, 请在命令行设置:
setenv XMODIFIERS @im=Chinput (csh)
export XMODIFIERS=@im=Chinput (sh)
.qti18nrc
