Writing to StatusBar

I am trying to write a line of text to the statusBar if the function results a failure. Any help that can be provide is always welcome thank you

Code:

void isOpen()
{
	int result;
 
	result = mbusProtocol.isOpen();
	if (result != FTALK_SUCCESS)
	{
 
		exit(EXIT_FAILURE);
	}
 
}

I know how to do it with QActions, but my my minds running a blank on how to do it in the above isOpen function

Code:

timer6Act = new QAction(QIcon("timer.png"), tr("&Timer 6"), this);
	timer6Act->setStatusTip(tr("Getting Data from Button6"));
	connect(checkAct, SIGNAL(clicked()), this, SLOT(timer6()));

Main code below

Code:

#include <stdio.h>
#include <stdlib.h>
#include "seniorgui.h"
#include "iconArea.h"

#include "MbusTcpMasterProtocol.hpp"
