1.初始化 QProcess绑定输出函数

1.      clipProcess=new QProcess(this);
2.      clipProcess->setProcessChannelMode(QProcess::MergedChannels);
3.      connect(clipProcess,SIGNAL(readyReadStandardOutput()),this,SLOT(read_slot()));
4.      connect(clipProcess,SIGNAL(readyReadStandardError()),this,SLOT(read_error()));
5.      clipProcess->start("cmd.exe");
6.      if (!clipProcess->waitForStarted())
7.            qDebug() << "Make failed:" << clipProcess->errorString();
8.        else
9.        {
10.           qDebug() << "clipProcess： " << clipProcess->readAll();
11.        }

 2.实现信息输出槽函数,

1. void Form::read_slot()
2. {
3.     while(clipProcess->canReadLine())
4.     {
5.         char output[1024];
6.         int ret = clipProcess->readLine(output,1023);
7.         qDebug() << ret;
8.         qDebug() << output;
9.  
10.         QString tmpstr;
11.         tmpstr=output; 
12.         qDebug() << tmpstr;
13.     }
14.     qDebug() << "read slot";
15. }

 3.逐行调用 （切记末尾加"\r\n",还有在lineEdit编辑输入例如"dir\r\n"会被识别为"dir\\r\\n"导致无法通过）

1.     clipProcess->write("cd c:/test/\r\n");
2.     clipProcess->waitForBytesWritten(1000);
3.     clipProcess->write("dir\r\n");
4.     clipProcess->waitForBytesWritten(1000);
