I was trying to set the size of the view loading the contents of the file to the parameters reported by teh file ( the DHW file format contains the width and height data of the file. Using setSceneRectangle() after loading the file wouldn't update the scene, at least not like I wanted it to. The text still originated at the top left corner, instead of updating so that the text moved slightly to the right and down. I tried various combinations of positive and negative offset values, nothing worked.
