[PyKDE] QProcess: more guidance needed

[Tina Isaksen]

Hi,

I need some QProcess pointers again I'm afraid.

I need to know when the process awaits input on it's stdin. I've been 
experimenting with QProcess::Communication flags but I can't make sense 
of it's output. I've also looked for some sort of SIGNAL (which would be 
ideal) but no luck there either. A code snippet:

    def doUpgrade(self):
    # Prepare widgets #
        self.mainTextWindow.setEnabled(1)
        self.mainTextWindow.setReadOnly(0)
        self.upgradeMessage.setEnabled(1)
        self.upgradeMessage.setReadOnly(0)
        self.mainTextWindow.clear()
        self.pbSaveMain.setEnabled(0)
       
        self.upgradeMessage.setText("Upgrading packages, please wait...")
       
        self.upgradeProcess = QProcess()
        self.connect(self.upgradeProcess, SIGNAL("readyReadStdout()"), 
self.readOutput)
        self.connect(self.upgradeProcess, SIGNAL("processExited()"), 
self.upgradeProcessExit)
        self.connect(self.upgradeProcess, SIGNAL("readyReadStderr()"), 
self.readUpgradeErrors)
        self.upgradeProcess.setArguments((QStringList.split(" ", 
"apt-get upgrade")))
        self.upgradeProcess.start()

       ###
       ### Need to know if upgradeProcess awaits input ###
       ###
       
    def readOutput(self):
        
self.mainTextWindow.append(QString(self.upgradeProcess.readStdout()))
                 
    def upgradeProcessExit(self):
        self.mainTextWindow.append("Done!")
       
        # Return widgets to defaults (foolproofing) #
        self.upgradeMessage.setText(" ")
        self.upgradeMessage.setEnabled(0)
        self.pbSaveMain.setEnabled(0)
        self.mainTextWindow.setReadOnly(1)
       
    def readUpgradeErrors(self):
        
self.mainTextWindow.append(QString(self.upgradeProcess.readStderr()))
