内容:
QProcess::startDetached(tr("c:\\test.xls"));
这么干貌似不行，有牛人用过吗，给点提示，不胜感激！
bool QProcess::startDetached ( const QString & program, const QStringList & arguments )
Starts the program program with the given arguments in a new process, and detaches from it. Returns true on success; otherwise returns false. If the calling process exits, the detached process will continue to live.
Note: Arguments that contain spaces are not passed to the process as separate arguments.
Unix: The started process will run in its own session and act like a daemon.
Windows: Arguments that contain spaces are wrapped in quotes. The started process will run as a regular standalone process.

补充：
我进行了简单测试，返回过来ret=0,error="Unknown error"。测试代码如下：
QProcess process;
bool ret = process.startDetached(tr("c:\\1.xls"));
QString error = process.errorString();

不是这样用的，你应该用QDesktopServices::openUrl(QUrl::fromLocalFile('xxxxxx.xls"));
