graphicsview

[QtUsr001]

In qtcreator I created a MainWindow, within that on the left, is Widget X and on the right is a graphicsview widget called graphicsview.

I have not called a setCentralWidget I think qtcreator has already done that for me.
since I have a lot of the functionality already working.

I have what must be a simple problem with getting the graphicsview to work.

in my MainWindow init I do

// ...other MainWindow init code that works

ui->setupUi(this);

scene = new QGraphicsScene();
ui->graphicsView->setScene(scene);
ellipseItem = scene->addEllipse( 10,10,100,100, QPen(Qt::blue), QBrush(Qt::blue) );

This all compiles and runs but nothing appears in the graphicsview.

I then tried adding a setCentralWidget( ui->graphicsView ). This creates an exception in the debugger
stopped at functionality for the other widget to the left of the graphicsview.

Any ideas?
