[question]redirecting stdout to display via widget?

[fantagol]

I'm looking for the solution from many days!!
This is the SIGNAL:

self.connect(self.process, QtCore.SIGNAL("readyReadStdout()"), self.readOutput)
        self.connect(self.process, QtCore.SIGNAL("readyReadStderr()"), self.readErrors)

self.connect(self.process, QtCore.SIGNAL("readyReadStdout()"), self.readOutput)
        self.connect(self.process, QtCore.SIGNAL("readyReadStderr()"), self.readErrors)

To copy to clipboard, switch view to plain text mode 

and this is the SLOT:

def readOutput(self):
        #print self.process.readStdout()
        self.textBrowser.append(QtGui.QString(self.process.readStdout()))
        #if self.process.isRunning()==False:
        #    self.textBrowser.append("\n Completed Successfully")
def readErrors(self):
        self.textBrowser.append("error: " + QtGui.QString(self.process.readLineStderr()))

def readOutput(self):
        #print self.process.readStdout()
        self.textBrowser.append(QtGui.QString(self.process.readStdout()))
        #if self.process.isRunning()==False:
        #    self.textBrowser.append("\n Completed Successfully")
def readErrors(self):
        self.textBrowser.append("error: " + QtGui.QString(self.process.readLineStderr()))

To copy to clipboard, switch view to plain text mode 

....Where is the mistake?
