在Qt应用程序中获取当前工作目录 [英] Get current working directory in a Qt application

问题描述

我使用Qt库在C ++中编写程序。在我的home bin目录中有一个符号链接到可执行文件。我想我的程序的当前工作目录是我与我的终端的目录（即 pwd 命令的结果）。我看到 QDir :: currentPath（）函数，但它返回二进制文件的目录。

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

谢谢RedX和Kaz的答案。我不明白为什么我给它的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;

它不如一行简单...但它适用于我。

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