possible to convert string/numbers to tray icon?

i have tried the trolltech example that creates system tray but i havent been able to find a way to convert string or value to icon so i could create weather application that shows temperature in system tray. is this possible in qt or do i have to create own icon for each number?

this was possible at least in c#

Code:

TrayIco::TrayIco( QWidget * parent, Qt::WFlags f) 
	: QMainWindow(parent, f)
{
	setupUi(this);
 
	QPixmap pixmap(16,16);
	pixmap.fill(Qt::transparent);
	QPainter painter(&pixmap);
	QString string;
	string = "48";
	painter.drawText(0,0,16,16,Qt::AlignHCenter | Qt::AlignVCenter, string); 
 
	ico = new QSystemTrayIcon(this);
 
	ico->setIcon(QIcon(pixmap));
 
	ico->show();  
}
