I'm trying to make an image scale inside of a QGraphicsView and having zero success. I did find this C++ question with what seemed to be the same problem:http://stackoverflow.com/questions/2489754/qgraphicsview-scrolling-and-image-scaling-cropping

I borrowed the approach of overriding the drawback/foreground. However when I run the script I'm greeted with a method_missing error:

method_missing: undefined method drawPixmap for #<Qt::Painter:0x7ff11eb9b088> QPaintDevice: Cannot destroy paint device that is being painted

What should I be doing to get the QGraphicsView to behave the way I want?

class Imageview < Qt::GraphicsView
attr_reader :pixmap 
  def initialize(parent=nil)
   # @parent=parent
    super()
     @pixmap=pixmap
    Qt::MetaObject.connectSlotsByName(self)

  end
  def loadimage(pixmap)
    @pixmap=pixmap
  end



  def drawForeground(painter, rect)
    #size=event.size()
    #item= self.items()[0] #Qt::GraphicsPixmapItem.new
    #pixmap=@pixmap 
    #painter=Qt::Painter.new
   [email protected](Qt::Size.new(rect.width,rect.height),Qt::KeepAspectRatio, Qt::SmoothTransformation)
   # painter.begin(self)
    painter.drawPixmap(rect,sized,Qt::Rect.new(0.0, 0.0, sized.width,sized.height))
    #painter.end()
   # item.setPixmap(sized)
    #painter.end
    self.centerOn(1.0,1.0)    
    #item.scale()
   # item.setTransformationMode(Qt::FastTransformation)

 # self.fitInView(item)
  end
 def updateSceneRect
    painter=Qt::Painter.new()
    drawForeground(painter,self.sceneRect)
  end
end
app=Qt::Application.new(ARGV)
#grview=Imageview.new
pic=Qt::Pixmap.new('pic')
grview=Imageview.new()
grview.loadimage(pic)
scene=Qt::GraphicsScene.new
#scene.addPixmap(pic)

grview.setScene(scene)
#grview.fitInView(scene)
grview.renderHint=Qt::Painter::Antialiasing | Qt::Painter::SmoothPixmapTransform
grview.backgroundBrush = Qt::Brush.new(Qt::Color.new(230, 200, 167))
