How to get current working directory path of a Qt application?

Question

I'm writing a program in C++ using the Qt library. I would like to get current working directory of my program. I found the QDir::currentPath() and QCoreApplication::applicationDirPath() function but they give back the directory where the application executable is. I don't wanna get the directory that contains the application executable.

I have uploaded the image which describes the path that I want to get.

enter image description here

Does anyone has any solutions?

Thank you!

what do you mean by I want the executable but not the binary ? — A. H., Jul 15 '13 at 04:21
`QDir::currentPath()` *is* the current application directory. It is *not* the directory containing the executable, unless those two directories happen to be the same. Which is what happens in your case because Creator launches the executable that way. — Nikos C., Jul 15 '13 at 04:31

Your application cannot know where the project is, because this is a qt-creator option. If you want to run your binary in the project path you have to setup your working directory inside qt-creator to the correct path. Then QDir::currentPath() will return the path you want to have.

goto: projects->[environment]->run->working directory

Checkout QCoreApplication::applicationDirPath(), it tries to figure out the directory the executable is in, rather than checking the current working directory

The source code directory is available via qmake variables and can "defined" for access within C++ source files:

# Demo.pro:
# set PROJECT_PATH to the "project path" with a trailing slash
DEFINES += PROJECT_PATH=\"\\\"$${_PRO_FILE_PWD_}/\\\"\"

// mainwindow.cpp
qDebug() << "Able to find main.cpp?..." 
         << QFile::exists(PROJECT_PATH "main.cpp"));

Output:

Able to find main.cpp?... true
