How to display the output of a process in a TextEdit widget in real time?

[qtzcute]

Still not working. The process is however running fine but TextEdit widget remains empty.
My MainWindow class

class MainWindow : public QMainWindow, private Ui::MainWindow
{
Q_OBJECT
public:
QProcess *myProcess;
MainWindow(QMainWindow *parent = 0);

private slots:
void updateError();
void updateText();
};

MainWindow.cpp

void MainWindow::On_pushButton_startAnalysis_Click()
{
	QObject *parent;
	myProcess= new QProcess(parent);
 
	QString program = "./memviz ";
	QCoreApplication::processEvents();		
	connect(myProcess, SIGNAL(readyReadStdError()), this, SLOT(updateError()));
	connect(myProcess, SIGNAL(readyReadStdOutput()), this, SLOT(updateText()));
	myProcess->start(program);
}
 
void MainWindow::updateError()
{
 QByteArray data = myProcess->readAllStandardError();
  textEdit_verboseOutput->append(QString(data));
}
 
void MainWindow::updateText()
{
   QByteArray data = myProcess->readAllStandardOutput();
   textEdit_verboseOutput->append(QString(data));
}

void MainWindow::On_pushButton_startAnalysis_Click()
{
	QObject *parent;
	myProcess= new QProcess(parent);

	QString program = "./memviz ";
	QCoreApplication::processEvents();		
	connect(myProcess, SIGNAL(readyReadStdError()), this, SLOT(updateError()));
	connect(myProcess, SIGNAL(readyReadStdOutput()), this, SLOT(updateText()));
	myProcess->start(program);
}

void MainWindow::updateError()
{
 QByteArray data = myProcess->readAllStandardError();
  textEdit_verboseOutput->append(QString(data));
}
 
void MainWindow::updateText()
{
   QByteArray data = myProcess->readAllStandardOutput();
   textEdit_verboseOutput->append(QString(data));
}

Is some error still hiding there from my egle eyes?
