QT.zipGuys,
I need help is the first time I'm working with threads and believe I'm doing something wrong. I have a file with the following structure:
192.168.0.1 executado OK
192.168.0.2 erro Sem_Acesso
192.168.0.3 executado OK
192.168.0.4 executado OK
192.168.0.5 executado OK
192.168.0.6 executado OK
192.168.0.7 executado OK
192.168.0.8 executado OK
192.168.0.9 executado OK
192.168.0.10 executado OK
192.168.0.11 executado OK
192.168.0.12 erro Sem_Acesso
192.168.0.13 erro Não_Responde_na_Rede

This file may vary in size, so I'm using the timer and threads, because my idea makes it a first reading and shows on the screen.
After'm trying to use a thread to run in parallel and a timer to wait a few seconds. But I can not do this update.
Following codes:
Corrida.h:
#ifndef CORRIDA_H
#define CORRIDA_H
#include <QThread>
#include <QTimer>
{
public:
void tempo();
};
void Corrida::tempo()
{
connect(timer, SIGNAL(timeout()), this, SLOT(ler_arquivos()));
timer->start(10);
}
#endif // CORRIDA_H
#ifndef CORRIDA_H
#define CORRIDA_H
#include <QThread>
#include <QTimer>
class Corrida : public QThread
{
public:
void tempo();
};
void Corrida::tempo()
{
QTimer *timer;
timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(ler_arquivos()));
timer->start(10);
}
#endif // CORRIDA_H
