    int timerId;

    protected:
    void timerEvent(QTimerEvent *event);

timerId = startTimer(1000);
....

void paginavenda::timerEvent(QTimerEvent *event)
{
  QDateTime dateTime = dateTime.currentDateTime();
  QString dateTimeString = dateTime.toString("yyyy-MM-dd hh:mm:ss");
  ui->data->setText(dateTimeString);
