Console application beginning

[Raccoon29]

Hi all,

newbie question after two years of honored Qt development
One sunny day I decided to kill myself trying to make up console applications...the beginning of the end.
I searched around for several hours, no examples, no a-b-c docs... I can't make a stupid hello world console application.

// main.cpp
#include <QtCore>
#include "backdoor.h"
 
int main(int argc, char *argv[])
{
	QCoreApplication a(argc,argv);
	Backdoor bd;
 
	bd.spit("Hello world!");
 
	return a.exec();
}

// main.cpp
#include <QtCore>
#include "backdoor.h"

int main(int argc, char *argv[])
{
	QCoreApplication a(argc,argv);
	Backdoor bd;

	bd.spit("Hello world!");

	return a.exec();
}

To copy to clipboard, switch view to plain text mode 

// backdoor.h
#include <QtCore>
 
class Backdoor : public QObject
{
	private:
		QTextStream out;
 
	public:
		Backdoor();
		void spit(QString str);
};

// backdoor.h
#include <QtCore>

class Backdoor : public QObject
{
	private:
		QTextStream out;

	public:
		Backdoor();
		void spit(QString str);
};

To copy to clipboard, switch view to plain text mode 

// backdoor.cpp
#include "backdoor.h"
 
Backdoor::Backdoor()
		:out(stdout)
{
}
 
void Backdoor::spit(QString str)
{
	out << str;
}

// backdoor.cpp
#include "backdoor.h"

Backdoor::Backdoor()
		:out(stdout)
{
}

void Backdoor::spit(QString str)
{
	out << str;
}

To copy to clipboard, switch view to plain text mode 

this code looks trivial, a stupid output, but I've not been able to make it run properly (no output!)...
1_ what's wrong with QTextStream? What did I forget?
2_ what is the basis concept to make console application? (an example of usage with an object and, possibly, an event to initiate me would be very very very apprecciated)
