How to get drag and drop events in GraphicsItem which is placed in GraphicsScene? - drag-and-drop

Question

I have graphicsview(attached graphicscene)setted as a centralwidget in scene i added 2 rect items(graphicsItem) (both are draggable). when i drag 1 rect item when its scene it gets drag enter event but when enters to other rect item its not getting drag enter event. How to resolve this?
Below is working example.
graphicsview.h
class GraphicsView : public QGraphicsView
{
public:
GraphicsView();
};
graphicsview.cpp
GraphicsView::GraphicsView()
{
//setAcceptDrops(true);
}
graphicsScene.h
class GraphicsScene : public QGraphicsScene
{
public:
GraphicsScene();
protected:
void dragEnterEvent(QGraphicsSceneDragDropEvent *event);
void dragMoveEvent(QGraphicsSceneDragDropEvent *event);
void dropEvent(QGraphicsSceneDragDropEvent *event);
};
graphicsScene.cpp
GraphicsScene::GraphicsScene()
{
}
void GraphicsScene::dragEnterEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << "Scene::dragEnterEvent";
event->acceptProposedAction();
}
void GraphicsScene::dragMoveEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << "Scene::dragMoveEvent";
event->acceptProposedAction();
}
void GraphicsScene::dropEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << "Scene::dropEvent";
event->acceptProposedAction();
}
graphicsRectItem.h
class GraphicsRectItem : public QGraphicsRectItem
{
public:
GraphicsRectItem();
static QString MimeType() { return QStringLiteral("job/x-job"); }
protected:
void mousePressEvent(QGraphicsSceneMouseEvent *event);
void mouseMoveEvent(QGraphicsSceneMouseEvent *event);
void mouseReleaseEvent(QGraphicsSceneMouseEvent *event);
void dragEnterEvent(QGraphicsSceneDragDropEvent *event);
void dragMoveEvent(QGraphicsSceneDragDropEvent *event);
void dropEvent(QGraphicsSceneDragDropEvent *event);
};
graphicsRectItem.cpp
GraphicsRectItem::GraphicsRectItem()
{
setAcceptDrops(true);
}
void GraphicsRectItem::mousePressEvent(QGraphicsSceneMouseEvent *event)
{
qDebug() << "RectItem::mousePressEvent";
setCursor(Qt::ClosedHandCursor);
}
void GraphicsRectItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
{
qDebug() << "RectItem::mouseMoveEvent";
if (QLineF(event->screenPos(), event-
>buttonDownScreenPos(Qt::LeftButton))
.length() < QApplication::startDragDistance()) {
QGraphicsRectItem::mouseMoveEvent(event);
return;
}
qDebug() << "drag before executed";
QByteArray itemData;
QString m_jobName = "rect";
DataStream dataStream(&itemData, QIODevice::WriteOnly);
dataStream << m_jobName ;
QMimeData *mimeData = new QMimeData;
mimeData->setData(GraphicsRectItem::MimeType(), itemData);
QDrag *drag = new QDrag(event->widget());
drag->setMimeData(mimeData);
drag->exec();
qDebug() << "drag executed";
setCursor(Qt::OpenHandCursor);
}
void GraphicsRectItem::mouseReleaseEvent(QGraphicsSceneMouseEvent *event)
{
qDebug() << "RectItem::mouseReleaseEvent";
setCursor(Qt::OpenHandCursor);
}
void GraphicsRectItem::dragEnterEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << "RectItem::dragEnterEvent";
event->acceptProposedAction();
}
void GraphicsRectItem::dragMoveEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << "RectItem::dragMoveEvent";
event->acceptProposedAction();
}
void GraphicsRectItem::dropEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << "RectItem::dropEvent";
event->acceptProposedAction();
}
Mainwindow.cpp
