获取 Qt 应用程序中的当前工作目录

问题描述

我正在使用 Qt 库用 C++ 编写程序.我的主 bin 目录中有一个指向可执行文件的符号链接.我希望我的程序的当前工作目录是我的终端所在的目录(即 pwd 命令的结果).我看到了 QDir::currentPath() 函数，但它返回了二进制文件所在的目录.

I'm writing a program in C++ using the Qt library. There is a symbolic link in my home bin directory to the executable. I would like the current working directory of my program to be the directory in which I am with my terminal (ie. the result of the pwd command). I saw the QDir::currentPath() function, but it gives back the directory where the binary is.

如何找到我当前的工作目录?

How can I find my current working directory?

推荐答案

感谢 RedX 和 Kaz 的回答.我不明白为什么我会给出exe的路径.我找到了另一种方法:

Thank you RedX and Kaz for your answers. I don't get why by me it gives the path of the exe. I found an other way to do it :

QString pwd("");
char * PWD;
PWD = getenv ("PWD");
pwd.append(PWD);
cout << "Working directory : " << pwd << flush;

它不如单行优雅......但它对我有用.

It is less elegant than a single line... but it works for me.
