DnDcontainer in QStateMachine, Drag and Drop no longer works?

[qtuser1]

I have a DnDcontainer in Screen3 below. Drag and Drop into the DnDcontainer used to work fine, until I updated the project to use QStateMachine and QAbstractTransition, to add simple transitions between screens. After adding the transitions, everything works except Drag and Drop to the DnDcontainer, the DnDcontainer::dragEnterEvent and DnDcontainer::dropEvent methods are never executed, and when hovering over the DnDcontainer, I get a circle with a slash through it. What am I missing here? How do I pass the Drag and Drop signal to the DnDcontainer?

@Screen1 *_screen1 = new Screen1;
Screen2 *_screen2 = new Screen2;
Screen3 *_screen3 = new Screen3;
QGraphicsProxyWidget *_screen2Proxy = new QGraphicsProxyWidget;
_screen2Proxy->setWidget(_screen2);
QGraphicsProxyWidget *_screen1Proxy = new QGraphicsProxyWidget;
_screen1Proxy->setWidget(_screen1);
QGraphicsProxyWidget *_screen3Proxy = new QGraphicsProxyWidget;
_screen3Proxy->setWidget(_screen3);

Pixmap *_stepper = new Pixmap(QPixmap(":/Images/imgs/stepper.png"));
Pixmap *_player = new Pixmap(QPixmap(":/Images/imgs/player.png"));
Pixmap *_stext = new Pixmap(QPixmap(":/Images/imgs/stepper-text.png"));

QWidget *_tb = new QWidget;
_tb->setStyleSheet("background-image: url(:/Images/imgs/menubar-full.png);background-repeat: repeat-x;");
_tb->setMinimumHeight(42);
_tb->setMinimumWidth(w);
QGraphicsProxyWidget *_tbProxy = new QGraphicsProxyWidget;
_tbProxy->setWidget(_tb);

scene->addItem(_tbProxy);
scene->addItem(_screen3Proxy);
scene->addItem(_screen1Proxy);
scene->addItem(_screen2Proxy);
scene->addItem(_stepper);
scene->addItem(_player);
scene->addItem(_stext);

QStateMachine machine;
QState *state1 = new QState(&machine);
QState *state2 = new QState(&machine);
QState *state3 = new QState(&machine);
machine.setInitialState(state1);

// state1
state1->assignProperty(_tbProxy, "geometry", QRect(0, 0, w, 42));
state1->assignProperty(_screen3Proxy, "geometry", QRect(0, 0, w, h));
state1->assignProperty(_screen1Proxy, "geometry", QRect(w, 50, w, h));
state1->assignProperty(_screen2Proxy, "geometry", QRect(2*w, 50, w, h));
state1->assignProperty(_stepper, "pos", QPointF(w-154, 0));
state1->assignProperty(_player, "pos", QPointF(w-154, 0));
state1->assignProperty(_stext, "pos", QPointF(w-154, 0));
// view
state1->assignProperty(_tbProxy, "opacity", qreal(1));
state1->assignProperty(_screen3Proxy, "opacity", qreal(1));
state1->assignProperty(_screen1Proxy, "opacity", qreal(0));
state1->assignProperty(_screen2Proxy, "opacity", qreal(0));
state1->assignProperty(_stepper, "opacity", qreal(1));
state1->assignProperty(_player, "opacity", qreal(1));
state1->assignProperty(_stext, "opacity", qreal(1));@

Hi and welcome to DevNet,

Are you sure that the DnDContainer has the right size ?

What properties do the other states set ?
