How to Redirect a Python Console output to a QTextBox

Question

I'm working on developing a GUI for the recompilation of Linux kernel. For this I need to implement 4-5 Linux commands from Python. I use Qt as GUI designer. I have successfully implemented the commands using os.system() call. But the output is obtained at the console. The real problem is the output of command is a listing that takes almost 20-25 min continuous printing. How we can transfer this console output to a text box designed in Qt. Can any one help me to implement the setSource() operation in Qt using source as the live console outputs.

Answer 1

self.process = QProcess()
self.connect(self.process, SIGNAL("readyReadStdout()"), self.readOutput)
self.connect(self.process, SIGNAL("readyReadStderr()"), self.readErrors)
tarsourcepath="sudo tar xvpf "+ self.path1
self.process.setArguments(QStringList.split(" ",tarsourcepath))
self.process.start()



def readOutput(self):

    self.textBrowser2.append(QString(self.process.readStdout()))
    if self.process.isRunning()==False:
        self.textBrowser2.append("\n Completed Successfully")




def readErrors(self):
    self.textBrowser2.append("error: " + QString(self.process.readLineStderr()))

This did the work quite good for me. thank you all.
