@aymen_ladiff Could you explain that you do not understand, the documentation is very clear. QGraphicsProxyWidget is a QGraphicsWidget, that is, the former is a specialized version that allows a QWidget to be easily embedded in a scene.

QGraphicsProxyWidget is for embedding an existing widget in a graphics scene. Use QGraphicsProxyWidget::setWidget() to specify the widget.

QGraphicsScene scene;
QTreeView treeView;
QGraphicsProxyWidget proxy;
proxy.setWidget(treeView);
scene.addItem(&proxy);

QGraphicsWidget is QGraphicsProxyWidget's base class. It can also be used as a base class for implementing a new widget with paintEvent(), etc overridden, or with a layout and children widgets.

@jeremy_k then so , if i will use a existing Widget i use QGraphicsProxyWidget and if i will make a new Widget by implementing the PaintEvent ,i use QGraphicsWidget ?

@aymen_ladiff Actually I simplify the rule: If you only want to embed a QWidget then only use a QGraphicsProxyWidget.
