I have placed a QGraphicsView widget on a main window and promoted it to
a custom widget.

I have created a scene attached to the view and added a pixmap to the scene.

I then loaded a jpeg image into the scene.

I copied the drawBackdrop method from the Qt Elastic Nodes sample.

I get the backdrop drawn but can not see the loaded image.

I've just started using designer - I can make this work coding by hand,
but I seem to be missing something when trying to get the image to
display when I do a show() on the top level main window generated by designer.

anyone one have a bit of sample code that works that they could share - would be greatly appreciated.
