<![CDATA[QListWidget drag indicator not showing]]>Hello, I have a simple list widget, and have following drag drop settings:
setDragEnabled(true);
setIconSize(QSize(m_PieceSize, m_PieceSize));
setAcceptDrops(true);
setDropIndicatorShown(true);
setDefaultDropAction(Qt::MoveAction);

But when drag an item and move inside list view, there is no drag indicator showing(no line/rectangle drawn on where dragging item will be dropped), what is the problem?

Thanks in advance.

I have read this Using Drag and Drop with Item Views document carefully, but the method it metioned just not working.
I have changed code to follow:
setDragEnabled(true);
setAcceptDrops(true);
setDropIndicatorShown(true);
setDefaultDropAction(Qt::MoveAction);
this->setDragDropMode(QAbstractItemView::InternalMove);
this->viewport()->setAcceptDrops(true);

But it still no change, when I drag item, I can see a black dot drawn on top left corner of list view:

But not fully drawn as line and rectangle which encapsulate list items.

@JonB Is there any simple example project to showcase drag and drop indicator works?

Did you read through Using Drag and Drop with Item Views? Try the examples there, e.g. maybe you need listWidget->setDragDropMode(QAbstractItemView::InternalMove); or the other code shown there.
