Error creating a animated menu

[CassioTC]

Hi,

I'm trying create a animated menu, i'ts a simple animation, just show and hide the menu.

But I get a error and can't figure that out

Menu *menu = new Menu();
 
    menu->setPos(0, scene->sceneRect().center().y() - (menu->boundingRect().center().y()*scaleT));
 
    scene->addItem(menu);
 
    setScene(scene);
 
    j->setPos(350,0);
    i->setPos(400,0);
 
    QPushButton *button = new QPushButton;
 
    //animaçao menu
    QStateMachine machine;
    QState *state_hide = new QState(&machine);
    QState *state_show = new QState(&machine);
    machine.setInitialState(state_show);
 
    state_show->assignProperty(menu, "pos", QPointF(110,200));
 
    state_hide->assignProperty(menu, "pos", QPointF(800,200));
 
    QAbstractTransition *t1 = state_show->addTransition(button, SIGNAL(clicked()),state_hide);
    QSequentialAnimationGroup *animation1SubGroup = new QSequentialAnimationGroup;
    animation1SubGroup->addPause(250);
 
    t1->addAnimation(animation1SubGroup);
    t1->addAnimation(new QPropertyAnimation(menu, "pos"));
 
    QAbstractTransition *t2 = state_hide->addTransition(button, SIGNAL(clicked()), state_show);
    t2->addAnimation(new QPropertyAnimation(menu, "pos"));
 
    machine.start();

Menu *menu = new Menu();

    menu->setPos(0, scene->sceneRect().center().y() - (menu->boundingRect().center().y()*scaleT));

    scene->addItem(menu);

    setScene(scene);

    j->setPos(350,0);
    i->setPos(400,0);

    QPushButton *button = new QPushButton;

    //animaçao menu
    QStateMachine machine;
    QState *state_hide = new QState(&machine);
    QState *state_show = new QState(&machine);
    machine.setInitialState(state_show);

    state_show->assignProperty(menu, "pos", QPointF(110,200));

    state_hide->assignProperty(menu, "pos", QPointF(800,200));

    QAbstractTransition *t1 = state_show->addTransition(button, SIGNAL(clicked()),state_hide);
    QSequentialAnimationGroup *animation1SubGroup = new QSequentialAnimationGroup;
    animation1SubGroup->addPause(250);

    t1->addAnimation(animation1SubGroup);
    t1->addAnimation(new QPropertyAnimation(menu, "pos"));

    QAbstractTransition *t2 = state_hide->addTransition(button, SIGNAL(clicked()), state_show);
    t2->addAnimation(new QPropertyAnimation(menu, "pos"));

    machine.start();
