在Qt应用程序中运行Windows命令提示符命令 [英] Running windows command prompt commands in a Qt application

问题描述

我需要通过Qt应用程序运行一个外部exe，该应用程序要求在Windows命令提示符下输入命令.

I need to run an external exe through Qt application which requires commands to be entered in windows command prompt.

  QString exePath = "C:\Windows\system32\cmd.exe";
  QProcess pro;
  pro.start(exePath);
  pro.execute("cmd.exe");

但是我得到的输出如下纯cmd提示

But I got output like below plain cmd prompt

但是我想要Windows命令提示符，例如预期的cmd

But I want windows command prompt like expected cmd

推荐答案

pro.start(exePath);
pro.execute("cmd.exe");

您不应同时使用这两种方法，QProcess :: execute是静态成员.

You should not use this two methods at same time, QProcess::execute is static member.

您需要启动分离的进程:

You need to start process detached:

QString exePath = "C:\Windows\system32\cmd.exe";
QProcess pro;
pro.startDetached(exePath);
pro.waitForStarted();
//Event Loop here
