Derived QListWidget Drag&Drop problem

[razdraz]

Hello,

I'm relatively new to Qt and I have problems to implement drag&drop function to my derived QListWidget class. While the drag is working perfectly, the drop does't. The cursor changes to "forbidden" after dragging an Item.
For now, I just want to get the x-Axis position of the drag and drop point (Drag is working).

Derived class:

.h:

class myQListWidget:public QListWidget
{
    Q_OBJECT
 
 public:
    myQListWidget(QWidget * parent = 0);
    ~myQListWidget();
 
 protected:
    void dropEvent(QDropEvent *event);
    void dragEnterEvent(QDragEnterEvent *event);
 
};

class myQListWidget:public QListWidget
{
    Q_OBJECT

 public:
    myQListWidget(QWidget * parent = 0);
    ~myQListWidget();

 protected:
    void dropEvent(QDropEvent *event);
    void dragEnterEvent(QDragEnterEvent *event);

};

To copy to clipboard, switch view to plain text mode 

.cpp:

myQListWidget::myQListWidget(QWidget * parent)
{
 
    this->setAcceptDrops(true);
    this->setDragDropMode(QAbstractItemView::DragDrop);
 
}
 
myQListWidget::~myQListWidget()
{
 
}
 
void myQListWidget::dropEvent(QDropEvent *event)
{
    xPositionDrop = event->pos().rx();
    qDebug() << "xPositionDrop: " << xPositionDrag;
}
 
void myQListWidget::dragEnterEvent(QDragEnterEvent *event)
{
    xPositionDrag = event->pos().rx();
    qDebug() << "xPositionDrag: " << xPositionDrag;
}

myQListWidget::myQListWidget(QWidget * parent)
{

    this->setAcceptDrops(true);
    this->setDragDropMode(QAbstractItemView::DragDrop);

}

myQListWidget::~myQListWidget()
{

}

void myQListWidget::dropEvent(QDropEvent *event)
{
    xPositionDrop = event->pos().rx();
    qDebug() << "xPositionDrop: " << xPositionDrag;
}

void myQListWidget::dragEnterEvent(QDragEnterEvent *event)
{
    xPositionDrag = event->pos().rx();
    qDebug() << "xPositionDrag: " << xPositionDrag;
}

To copy to clipboard, switch view to plain text mode 

When using the original QListWidget class, the cursor does not change to "forbidden" and drops work properly.
What am I missing here?

Thanks.

Neither your dragEnterEvent() nor your dropEvent() calls acceptProposedActin() on the event.
See Dropping here: http://doc.qt.io/qt-5.4/dnd.html
There is more item view drag and drop information here: http://doc.qt.io/qt-5.4/model-view-p...ith-item-views

The event->acceptProposedAction() thing makes it work ;-) thanks
