Looping inside console application

sbielmann

Hello All,

I wonder if somebody can advice what the best practice is to loop inside a Qt console application.
My test example below should:

send request over network
handle response
if response is "quit" leave, else go to point 1

Here the example code:

Test::Test() : network(this) {
  QObject::connect(network, SIGNAL(handleResponse(const QString &)),
      this, SLOT(slotHandleResponse(const QString &)));
}

void Test::run() {
  network->sendRequest();
}

void Test::slotHandleResponse(const QString response) {
  if(response == "quit") {
    emit finished();
  } else {
    // send next request
    run();
  }
}

int main(int argc, char **argv) {
  QCoreApplication app(argc, argv);
  Test test();
  QObject::connect(&test, SIGNAL(finished()), &app, SLOT(quit()));
  QTimer::singleShot(0, &test, SLOT(run()));
  return(app.exec());
}

Is it ok to call run() from within slotHandleResponse() again and again until I get "quit" ? Or should I use QTimer::singleShot() again ? Or something else ?

Thanks for any help

Hi,

What about using a QStateMachine ? You'd need a custom transition to handle the "end/restart" use case.
