Flowables need to report the width and height of the wrapped contents; so you 
need to override the wrap method. In this simple case I guess you need something 
like

     def wrap(self,aW,aH):
         canv = self.canv
         return canv._leading, canv.stringWidth(self.text)

because width and height are interchanged.
