hi friends,
i gone through one good examlpe which use QProcess() and in that i have one doubt ...
i try all the assistant documents but cant find ... what is the difference between this two .. to get readyReadStandardError() from QProcess()

Qt Code:

Switch view

1.
              QString path = process.readAllStandardError();
              path = outputtextedit->setText(path);
 
          2.
               QByteArray newData = process.readAllStandardError();
             QString text = outputTextEdit->toPlainText()
                                      + QString::fromLocal8Bit(newData);
                    outputTextEdit->setPlainText(text);

1.
              QString path = process.readAllStandardError();
              path = outputtextedit->setText(path);

          2.
               QByteArray newData = process.readAllStandardError();
             QString text = outputTextEdit->toPlainText()
                                      + QString::fromLocal8Bit(newData);
                    outputTextEdit->setPlainText(text);

To copy to clipboard, switch view to plain text mode

why we need to convert QString as like 2 nd one .... what will happen if i use 1 st condition ..?
