Making a qt3d cube appear transparent

[sunil.nair]

Hi,

I create a cursor in qt3d using the following lines of code:

@QGLBuilder cursor_builder;
cursor_builder <<QGL::Faceted;
cursor_builder <<QGLCube(0.15);
cursor=cursor_builder.finalizedSceneNode();@

I bind a texture to this cube using
@handcursor.setImage(QImage(QLatin1String("D:/transparent.png")));
std::cout<<"constructor called"<<std::endl;@

Now I want to do two things:

1. Make the cube appear transparent
2. Bind a transparent texture onto the cube
