1、#include "mainwindow.h"中

添加頭文件：

#include <QProcess>

添加成員：

QProcess *myprocess;

?添加槽函數聲明：

void showCMDResult(); void showCMDState(QProcess::ProcessState state); void showCMDError(); void showCMDFinished(int exitCode, QProcess::ExitStatus exitStatus);

2、mainwindow.cpp中

構造函數中實例化：

myprocess = new QProcess;

添加槽函數：

connect(myprocess, SIGNAL(readyRead()), this, SLOT(showCMDResult())); connect(myprocess, SIGNAL(stateChanged(QProcess::ProcessState)),this, SLOT(showState(QProcess::ProcessState))); connect(myprocess, SIGNAL(error(QProcess::ProcessError)),this, SLOT(showCMDError())); connect(myprocess, SIGNAL(finished(int,QProcess::ExitStatus)),this, SLOT(showCMDFinished(int, QProcess::ExitStatus)));

實現槽函數：

void MainWindow::showCMDResult() {QString strTemp=QString::fromLocal8Bit(myprocess->readAll());ui->textEdit->append(strTemp); }void MainWindow::showCMDState(QProcess::ProcessState state) {if(state==QProcess::NotRunning)qDebug() << "Not Running";else if(state==QProcess::Starting)?qDebug() << "Starting";;elseqDebug() << "Running"; }void MainWindow::showCMDError() {ui->textEdit->append(myprocess->errorString()); }void MainWindow::showCMDFinished(int exitCode, QProcess::ExitStatus exitStatus) {ui->textEdit->append(QString("啟動結束：").append("退出代碼：").append(QString::number(exitCode)).append("退出狀態：").append(QString::number((uint)exitStatus))); }?

?? ??3、啟動cmd.exe

QStringList argument; argument<<"/C"<<"python"<<ui->lineEdit_filepath->text()<<ui->lineEdit_inputpara->text(); myprocess->start("cmd.exe",argument); ui->textEdit->append("啟動cmd.exe"); // 等待進程啟動 if (!myprocess->waitForStarted()) {ui->textEdit->append("啟動失敗");return; }??
