title: How do I make the top left of a QGraphicsScene coincide with the top left of my QGraphicsView?
body: <p>I always have trouble with the QGraphicsScene coordinate system. My scene is created quite simply like so:</p>
  
  <pre><code>scene = new QGraphicsScene(this);
  this-&gt;setScene(scene);
  </code></pre>
  
  <p>where this is QGraphicsView. Now I want to draw a rectangle at (0,0) This creates rectangle that is roughly in the middle of the screen. How do I make it so that (0,0) corresponds to the upper left corner of my view? This is so I know where I can position anything...</p>
