QT 获取exe所在路径

1. Linux：

std::string strExepath(_pgmptr);

2.VS：

char arrPath[MAX_PATH_LENGTH];
    memset(arrPath, 0, sizeof(char) * MAX_PATH_LENGTH);
    GetModuleFileName(NULL, arrPath, MAX_PATH_LENGTH);
    std::string strExeName(arrPath);

3.QT

QCoreApplication::applicationDirPath();

QCoreApplication::applicationFilePath();

QCoreApplication::applicationName();
