QStateMachine doesn't starts :(

[nudels]

Hello Guys

i have a problem with the QStateMachine. I want to use it for seting static positions for some GraphicsObjects, but it doesn't start

here is my code for init the machine and states:

void BedienelementController::initMachine()
{
    _machine = new QStateMachine(this);
    initState();
}
 
 
void BedienelementController::initState()
{
    _stateList.append(new QState());
    _stateList.append(new QState());
    _stateList.append(new QState());
 
 
    _stateList.at(0)->addTransition(this, SIGNAL(jsRechts()), _stateList.at(1));
    _stateList.at(1)->addTransition(this, SIGNAL(jsRechts()), _stateList.at(2));
    _stateList.at(2)->addTransition(this, SIGNAL(jsRechts()), _stateList.at(0));
 
    _machine->addState(_stateList.at(0));
    _machine->addState(_stateList.at(1));
    _machine->addState(_stateList.at(2));
 
    _machine->setInitialState(_stateList.at(0));
 
    _machine->start();
 
 
    _stateList.at(0)->assignProperty(_textFelderH.at(0), "pos", *_punkteListe.at(0));
    _stateList.at(0)->assignProperty(_textFelderH.at(1), "pos", *_punkteListe.at(1));
    _stateList.at(0)->assignProperty(_textFelderH.at(2), "pos", *_punkteListe.at(2));
 
    _stateList.at(1)->assignProperty(_textFelderH.at(0), "pos", *_punkteListe.at(1));
    _stateList.at(1)->assignProperty(_textFelderH.at(1), "pos", *_punkteListe.at(2));
    _stateList.at(1)->assignProperty(_textFelderH.at(2), "pos", *_punkteListe.at(0));
 
    _stateList.at(2)->assignProperty(_textFelderH.at(0), "pos", *_punkteListe.at(2));
    _stateList.at(2)->assignProperty(_textFelderH.at(1), "pos", *_punkteListe.at(0));
    _stateList.at(2)->assignProperty(_textFelderH.at(2), "pos", *_punkteListe.at(1));
   qDebug() << _machine->isRunning();
 
}

void BedienelementController::initMachine()
{
    _machine = new QStateMachine(this);
    initState();
}


void BedienelementController::initState()
{
    _stateList.append(new QState());
    _stateList.append(new QState());
    _stateList.append(new QState());


    _stateList.at(0)->addTransition(this, SIGNAL(jsRechts()), _stateList.at(1));
    _stateList.at(1)->addTransition(this, SIGNAL(jsRechts()), _stateList.at(2));
    _stateList.at(2)->addTransition(this, SIGNAL(jsRechts()), _stateList.at(0));

    _machine->addState(_stateList.at(0));
    _machine->addState(_stateList.at(1));
    _machine->addState(_stateList.at(2));

    _machine->setInitialState(_stateList.at(0));

    _machine->start();


    _stateList.at(0)->assignProperty(_textFelderH.at(0), "pos", *_punkteListe.at(0));
    _stateList.at(0)->assignProperty(_textFelderH.at(1), "pos", *_punkteListe.at(1));
    _stateList.at(0)->assignProperty(_textFelderH.at(2), "pos", *_punkteListe.at(2));

    _stateList.at(1)->assignProperty(_textFelderH.at(0), "pos", *_punkteListe.at(1));
    _stateList.at(1)->assignProperty(_textFelderH.at(1), "pos", *_punkteListe.at(2));
    _stateList.at(1)->assignProperty(_textFelderH.at(2), "pos", *_punkteListe.at(0));

    _stateList.at(2)->assignProperty(_textFelderH.at(0), "pos", *_punkteListe.at(2));
    _stateList.at(2)->assignProperty(_textFelderH.at(1), "pos", *_punkteListe.at(0));
    _stateList.at(2)->assignProperty(_textFelderH.at(2), "pos", *_punkteListe.at(1));
   qDebug() << _machine->isRunning();

}

To copy to clipboard, switch view to plain text mode 

The Debug output allways says "false".

_stateList is a QList<QState*>, _punkteListe a QList<QPointF*> and _textFelderH ar my class inherited from QGraphicsObject
The "BedienelementController"-Class is inherited from QWidget.

i hope smbdy can give me a hint


EDIT:
okay... i have to read the online documentation... the statemachine can only be started when a event-loop is running...
sry

Thanks!

with best regards
