The goal is to draw the following:
Qt Code: 
  1. +-----------------+             +-----------------+
  2. |                 |             |                 |
  3. |                 |[]------\    |                 |[] - - - - 
  4. |      PIXMAP     |         \-[]|      PIXMAP     |              OTHER OBJECTS
  5. |                 |[]           |                 |[] - - - - 
  6. |                 |             |                 |
  7. +-----------------+             +-----------------+
  8.     Object Nr.1                    Object_2
To copy to clipboard, switch view to plain text mode 
Each Object has 0 - n connectors on each side, in the middle a QGraphicsPixmapItem and under the object in the middle the Object name.
Between the connectors i would like to add a line which moves also if one of the connected objects moves (like Visio)

Currently i have the QGraphicsPixmapItem implemented, but i don't know how to implement the QGraphicsTextItem and the lines between the connectors and the connectors self.

@aamer4yu: I tried to put the following in my class (inherited from QGraphicsPixmapItem) as follows:
Qt Code: 
  1. DiagramImageItem::DiagramImageItem(DiagramType diagramType, QMenu *contextMenu,
  2.              QGraphicsItem *parent, QGraphicsScene *scene)
  3.     : QGraphicsPixmapItem(parent, scene)
  4. {
  5.  
  6. 	connect(scene, SIGNAL(retrieveItemData(const QString&, const QVariant&)),
  7. 			this, SLOT(retrieveItemData(const QString&, const QVariant&)));
  8. 	obj_id++;
  9.     myDiagramType = diagramType;
  10.     myContextMenu = contextMenu;
  11.  
  12. 	this->obj_name = object_name.toLower();
  13. 	this->obj_type_str = object_type;
  14. 	this->obj_type = myDiagramType;
  15. 	setToolTip(this->obj_name);
  16. 	setObjectName(object_name);
  17.  
  18. 	setFlag(QGraphicsItem::ItemIsMovable, true);
  19. 	setFlag(QGraphicsItem::ItemIsSelectable, true);
  20.  
  21.     textItem = new DiagramTextItem();
  22.     textItem->setPlainText(this->obj_name);
  23.     textItem->setFont(QFont("courier"));//myFont);
  24.     //textItem->setTextInteractionFlags(Qt::TextEditorInteraction);
  25.     textItem->setZValue(this->zValue());
  26.     textItem->setDefaultTextColor(QColor(0, 0, 0));//myTextColor);
  27.     textItem->setPos(this->pos().x()+20, this->pos().y()+100);//+266);//mouseEvent->scenePos());
  28.     this->scene()->addItem(textItem);
  29.    // addItem(textItem);
  30. }
To copy to clipboard, switch view to plain text mode 

Put i didn't see any text. As base of the code i used the diagram example from QT 4.3

Kind Regards
