How to get executable name in Qt

Question

I run a Qt application, what I want to know is this running binary file name.

Answer 1

I must (partially) disagree with the other comments that it is not a Qt question: There is a Qt method QCoreApplication::applicationFilePath() which gives the directory+filename of the executable.

On Linux this will try to use /proc, and on Windows perhaps GetModuleFileName(). According to the docs it will fall back to argv[0].

You could then use QFileInfo to split it into an executable name and a directory.

QFileInfo(QCoreApplication::applicationFilePath()).fileName()
