Hi Matteo,

Recently, I also tried to embed VPython window into QT using PyQT, but  
also with no luck :(
Have you discovered anything new on that matter?

Below is my code:

from PyQt4 import QtCore, QtGui

from visual import *

class Ball(QtGui.QGraphicsItem):
     def __init__(self):
         super(Ball, self).__init__()

         self.shape = sphere(pos=(17.047, 14.099, 3.625),radius=1)


if __name__ == '__main__':

     app = QtGui.QApplication(sys.argv)

     scene_qt = QtGui.QGraphicsScene()
     scene_qt.setSceneRect(-300, -300, 600, 600)
     scene_qt.setItemIndexMethod(QtGui.QGraphicsScene.NoIndex)

     # scene2 = display(title='Graph of position', width=600,  
height=200, center=(5,0,0), background=(0,1,1))

     ball = Ball()
     scene_qt.addItem(ball)

     # ball = sphere(pos=(17.047, 14.099, 3.625),radius=1)

     view = QtGui.QGraphicsView(scene_qt)
     view.show()

     sys.exit(app.exec_())



Best,
