problem with slots

[babu198649]

hi
in the following code the signal is not connected to slot.

#include <QApplication>
#include <QtGui>
 
class push : public QPushButton
{
 
public slots:
	void hi();
 
public:
	push(QWidget *parent=0);
};
 
 
push::push(QWidget *parent) :
	QPushButton(parent)
{
	connect(this, SIGNAL(clicked()), this, SLOT(hi()));
}
 
void push::hi()
{
	qDebug()<<"hioo";
}
 
int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
 
	push W;
	W.show();
 
	return app.exec();
}

#include <QApplication>
#include <QtGui>

class push : public QPushButton
{

public slots:
	void hi();

public:
	push(QWidget *parent=0);
};


push::push(QWidget *parent) :
	QPushButton(parent)
{
	connect(this, SIGNAL(clicked()), this, SLOT(hi()));
}

void push::hi()
{
	qDebug()<<"hioo";
}

int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
	
	push W;
	W.show();

	return app.exec();
}

To copy to clipboard, switch view to plain text mode 

this code compiles and executes but gives the warning
Object::connect: No such slot QPushButton::hi()

where did the code wnt wrong
