Simple QTimer help

[philips]

Hi guys,

I was wondering if someone could help me out with creating a button that when clicked, will print “Hello World” every 5seconds until the button is pressed again.

So far I have:

void button_clicked()
{
	QTimer *timer = new QTimer();
 
	If ( button->text == “Start” )
	{
        button->setText(“Stop”);
		timer->start(5000);
		printf(“Hello World\n”);
	}
	else
	{
		timer->stop();
		button->setText(“Start”);
	}
}

void button_clicked()
{
	QTimer *timer = new QTimer();

	If ( button->text == “Start” )
	{
        button->setText(“Stop”);
		timer->start(5000);
		printf(“Hello World\n”);
	}
	else
	{
		timer->stop();
		button->setText(“Start”);
	}
}

To copy to clipboard, switch view to plain text mode 

Obviously, as you can probably tell, I am new to Qt and threading. Right now, it just prints out the Hello World once. How do I make it keep going every 5 seconds?
Do I have to make it an event or something?

Any help code and explanation wise would be greatly appreciated.

Thanks,
