Console output in a Qt GUI app?

Question

I have a Qt GUI application running on Windows that allows command-line options to be passed and under some circumstances I want to output a message to the console and then

Answer 1

void Console()
{
    AllocConsole();
    FILE *pFileCon = NULL;
    pFileCon = freopen("CONOUT$", "w", stdout);

    COORD coordInfo;
    coordInfo.X = 130;
    coordInfo.Y = 9000;

    SetConsoleScreenBufferSize(GetStdHandle(STD_OUTPUT_HANDLE), coordInfo);
    SetConsoleMode(GetStdHandle(STD_OUTPUT_HANDLE),ENABLE_QUICK_EDIT_MODE| ENABLE_EXTENDED_FLAGS);
}

int main(int argc, char *argv[])
{
    Console();
    std::cout<<"start@@";
    qDebug()<<"start!";

You can't use std::cout as others have said,my way is perfect even for some code can't include "qdebug" !
