drag&drop from QTreeWidget to QGraphicsPixmapItem

[hakiim35]

Hi, I want to drag a QTreeWidgetItem from my QTreeWidget to the QGraphicsPixmapItem.
Do I have to reimplement mouse events in the drag site.
I reimplemented them such as

mousePressEvent(QGraphicsSceneMouseEvent *e); 
mouseMoveEvent(QGraphicsSceneMouseEvent *e); 
mouseReleaseEvent etc..

mousePressEvent(QGraphicsSceneMouseEvent *e); 
mouseMoveEvent(QGraphicsSceneMouseEvent *e); 
mouseReleaseEvent etc..

To copy to clipboard, switch view to plain text mode 

but the program flow never falls into the mouse events in debug mode.
I have also performed setAcceptDrops(true) in my QGraphicsPixmapItem's constructor and reimplemented the dropEvent( QDropEvent *event ) but again the flow never falls inside it.

How will I be able to perform the drag & drop?
My aim is to send the currently dragged QTreeWidgetItem's text to the QGraphicsPixmapItem.

Best regards.

Before starting to debug make you sure you have these things set properly:

- A correct Start of a drag operation (enable dnd and reimplement the necessary event handler i can send you to this link http://doc.qt.nokia.com/4.6/dnd.html

ad this one

-The QGraphicsView container where you want to drop your item is interactive with : ( void QGraphicsView::setInteractive ( bool allowed ) ).

- The QGraphicsView container where you want to drop your item accept drop events with : QGraphicsView::setAcceptDrops(true);

- if you're subclassing QGraphicsPixmapItem set your class it to accept drop with : void QGraphicsItem::setAcceptDrops ( bool on )

then reimplement

dropEvent ( QGraphicsSceneDragDropEvent * event ) of your subclass and process the data contained in the event->mimeData().

This data (the text ) should be loaded in the start drag processing.
