implemet a timer

[wagmare]

try this

timer->start(1000);
connect(timer, SIGNAL(timeOut()),this, SLOT(timerCall()));
 
::timerCall()   //slot
{ 
      if( port->DataAvalable){
port->read();
   // can call any private function 
   }
}

timer->start(1000);
connect(timer, SIGNAL(timeOut()),this, SLOT(timerCall()));

::timerCall()   //slot
{ 
      if( port->DataAvalable){
port->read();
   // can call any private function 
   }
}

To copy to clipboard, switch view to plain text mode 

so every time the timer calls this slot every 1 sec ... if data is available it will do the operation or there emit your own private signal
