关于QProcess的进程中的运行先后测试

QProcess *myprocess = new QProcess();

connect(myprocess,SIGNAL(started()),this,SLOT(slotStarted()));

connect(myprocess,SIGNAL(finished(int)),this,SLOT(slotFinished(int)));

myprocess->setProcesschannelMode(QProcess::Fowaredchannels);

qDebug()<<”process start:::::”;

myprocess->start(progrem, argument);

myprocess->waitForStarted(-1);

myprocess->waitForFinished(-1);

qDebug()<<”process finished:::”;

如果不加waitFor函数的话，则myprocess命令会正常执行下去，程序不需要等待命令开始或者结束再去执行下一个语句，
