How to get executable name in Qt
I run a Qt appli开发者_运维知识库cation, what I want to know is this running binary file name.
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()
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
Again not really a Qt question. To find the name of the binary file executed it would be something like.
#include <iostream>
using namespace std;
int main(int argc, char **argv)
{
cout << argv[0] << endl;
return 0;
}
