Timer not timing out?

[Mariane]

I have in the constructor:

MazeField::MazeField( QWidget *parent, const char *name ) : QWidget( parent, name ) {
   (...)
   recordingTimer = new QTimer( this, "recordingTimer" );
   connect(recordingTimer,SIGNAL(timeout()),this,SLOT(updateRecordingTime())); 
   (...)
   }

MazeField::MazeField( QWidget *parent, const char *name ) : QWidget( parent, name ) {
   (...)
   recordingTimer = new QTimer( this, "recordingTimer" );
   connect(recordingTimer,SIGNAL(timeout()),this,SLOT(updateRecordingTime())); 
   (...)
   }

To copy to clipboard, switch view to plain text mode 

and in the same file, below:

void MazeField::updateRecordingTime() {
	recordingTimerCount = (unsigned) time (NULL) - recordingTimerStart;
	cout << "Recording time is " << recordingTimerCount << endl;
	emit recordingTimeChanged(recordingTimerCount);
	}

void MazeField::updateRecordingTime() {
	recordingTimerCount = (unsigned) time (NULL) - recordingTimerStart;
	cout << "Recording time is " << recordingTimerCount << endl;
	emit recordingTimeChanged(recordingTimerCount);
	}

But this last bit doesn't seem to get reached, it doesn't even write the time...

Please help.

How do you start that timer?

[Mariane]

Start? I thought they just started when declared

No, you have to start() them. And that's reasonable, because you can use a single timer multiple times.

Thank you very much.

Here's an example from Qt docs:

QTimer *timer = new QTimer( myObject );
connect( timer, SIGNAL(timeout()), myObject, SLOT(timerDone()) );
timer->start( 2000, TRUE ); // 2 seconds single-shot timer

QTimer *timer = new QTimer( myObject );
connect( timer, SIGNAL(timeout()), myObject, SLOT(timerDone()) );
timer->start( 2000, TRUE ); // 2 seconds single-shot timer
