Try using a Here Document :
Bash
[k5054@localhost]$ sudo ps
[sudo] password for k5054: 
sudo: no password was provided
sudo: a password is required
[k5054@localhost]$ cat example.cpp
 #include <iostream>
 #include <cstdio>
 #include <cstdlib>

int main()
{
    std::string userPass{"myPassword"};
    std::string command{"sudo -S ps -lf 2>/dev/null <<_EOF\n" + userPass + "\n_EOF"};
    FILE *pipe = popen(command.c_str(), "r");
    char *line = NULL;
    size_t len = 0;
    ssize_t rlen;
    while( (rlen = getline(&line, &len, pipe))  > 0) {
        line[--rlen] = '\0'; // trim trailing newline
        std::cout << line << '\n';
    }

    pclose(pipe);
    free(line);

}
[k5054@localhost]$ make example
g++ -Wall -Wextra -ggdb    example.cpp   -o example
[k5054@localhost]$ ./example

You should be able to modify that for use with QProcess.
Note that if you don't redirect stderr to /dev/null, the SSH password prompt goes to wherever stderr is pointing to.
