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

The Qapplication parses the commandline arguemnts, the first entry is the name of the executable - this is roughly the same as argv[0] in standard C but has a few extra complexities on windows if you have a Unicode build or if the application is started as a service

See http://doc.qt.io/qt-5/qcoreapplication.html#arguments
