I don't seem to able to find the problem. Please help

public slots:
void toggleState();

== RArrow constructor ==
timer = new QTimer();
QObject:: connect(timer, SIGNAL(timeout()), this, SLOT(toggleState()));

void RArrow::toggleState()
{ state = !state;
}

RArrow

Is your class RArrow inherited from QObject ? Most probably you missed inheriting it.
