QProcess again ..

[cmeliak]

it works fine now:

ServerMainWindow::ServerMainWindow(QWidget* parent, const char* name)
  : MainWindowBase(parent, name),
  m_server(0)
{
  m_clients.setAutoDelete(true);
 
 
  proc    = new QProcess(this);
 
  proc->addArgument("ipconfig");
  proc->addArgument("-all");
 
 
  QObject::connect(proc,SIGNAL(readyReadStdout()),this,SLOT(readFromStdout()));
  QObject::connect(m_start, SIGNAL(clicked()), this, SLOT(slotStartClicked()));
  QObject::connect(m_stop, SIGNAL(clicked()), this, SLOT(slotStopClicked()));
  proc->start();
}

      textEdit1->setText(data);
            sendToClients(data);

  {
    QSocket* sock = iter.current()->socket();
    QTextStream stream(sock);
    stream << text;
  }
}

To copy to clipboard, switch view to plain text mode 

but still my client doesn't recive stdout from ipconfig
function sendToClients(data); should send QString to void ServerMainWindow::sendToClients(const QString& text)

is the function sendToClients(const QString& text) correct? or could be there some issue in the client application?

client function that recieves data from server app is:

void ClientMainWindow::slotRead()
{
  QString text;
  while (m_socket->canReadLine())
    text += m_socket->readLine();
 
  if (!text.isNull())
    appendText(text, Output);
}
 
 
where 
 
 
 
void ClientMainWindow::appendText(const QString& text, Mode mode)
{
  switch (mode)
  {
    case System:
      m_textEdit->setColor(Qt::blue);
      break;
 
    case Error:
      m_textEdit->setColor(Qt::red);
      break;
 
    default:
      m_textEdit->setColor(Qt::black);
      break;
  }
 
  m_textEdit->append(text);
}

void ClientMainWindow::slotRead()
{
  QString text;
  while (m_socket->canReadLine())
    text += m_socket->readLine();

  if (!text.isNull())
    appendText(text, Output);
}


where 



void ClientMainWindow::appendText(const QString& text, Mode mode)
{
  switch (mode)
  {
    case System:
      m_textEdit->setColor(Qt::blue);
      break;

    case Error:
      m_textEdit->setColor(Qt::red);
      break;

    default:
      m_textEdit->setColor(Qt::black);
      break;
  }

  m_textEdit->append(text);
}
