QT界面边框透明问题。

meguoe

公司用QT开发的程序界面，在服务器上运行，2003服务器和2008服务器在本地运行时一切正常，但是如果用远程桌面进入，程序就无法显示界面了。（可以看到进程已经启动，而且程序任务图标的右键也可以显示出来。）已经找到问题，【this->setAttribute(Qt::WA_TranslucentBackground, true); 】注释掉设置透明的代码或将他设置为false，远程就可以打开了，但是界面整体效果就不好看了。
把代码贴出来，大家看看有没有好的解决方法。QQ：275990463  可以远程看环境

可能是远程桌面的窗口管理器为了保证性能，牺牲了显示的效果

毕竟你运行的是服务器版，自然不会考虑有多好看
