and the .cpp is attached.

at the very least let me know where is the widget subclass.

QGraphicsItem do not inherit the QWidget class so you cannot place a lineEdit inside it...
what you can do is make another QGraphicsProxyWidget and put lineEdit inside it. read the doc of this.. then like you have inserted your node into a scene... add you proxywidgetitem to the scene as welll.. make sure to play with the z-order of proxywidget so that it always shows above the other items...

NO WONDER!!!! -_-! so what i wan still can be done right? using the QGraphicsProxyWidget class? alright i go read about it. you are a real Guru... lol
