QProcess::startDetached() 但隐藏控制台窗口 [英] QProcess::startDetached() but hide console window

问题描述

是否可以在隐藏控制台窗口的同时使用 QProcess::startDetached() 在 Windows 中运行程序?QProcess::start() 会隐藏控制台窗口，但 QProcess::startDetached() 不会，至少在默认情况下不会.

Is it possible to run a program in Windows using QProcess::startDetached() while hiding its console window? QProcess::start() will hide the console window but QProcess::startDetached() does not, at least by default.

我可以使用 QProcess::start() 但是我必须等待子程序完成否则析构函数会强制终止它，我想立即关闭我的程序启动子进程后.

I could use QProcess::start() but then I'd have to wait for the child program to finish or the destructor would force-terminate it, and I want to close my program immediately after starting the child process.

推荐答案

我遇到了完全相同的问题，无法以干净的方式解决它.我找到了 2 个选项:

I had exactly the same problem, and could not solve it in a clean way. I have found 2 options:

1. Hacky 方法:子类 QProcess 并在启动进程后调用 setProcessState(QProcess::NotRunning);.这将阻止析构函数终止进程.但它依赖于 QProcess
的实现细节

2. 创建内存泄漏:在堆上动态创建QProcess，但永远不会删除它，因此永远不会调用其析构函数

1. Hacky way: Subclass QProcess and call setProcessState(QProcess::NotRunning); after starting the process. This will prevent the destructor to terminate the process. But it relies on an implementation detail of QProcess

2. Create a memory leak: Dynamically create the QProcess on the heap, but never delete it, and thus never invoke its destructor

{
    QProcess *process = new QProcess;
    process->start("taskkill", QStringList() << "/f" << "/im" << "My Service.exe");
}
