Notice that everything between [exBegin] and [exEnd] is extracted by the html-doc generator to create nicely formatted and clickable executable examples in the generated html-doc. (see the browsers class-documentation menu items for more) trying the widget as standAlone view:
   DisplayObjectView new open
embedded in another view:
   |top v|

   top := StandardSystemView new.
   top extent:300@300.
   v := DisplayObjectView new.
   v origin:0.0@0.0 corner:1.0@1.0.
   v model:(Polygon vertices:{ 10@10 . 30@10 . 20@20 . 10@10 }).
   top add:v.
   top open
   |top v|

   top := StandardSystemView new.
   top extent:300@300.
   v := DisplayObjectView new.
   v origin:0.0@0.0 corner:1.0@1.0.
   v model:(Image fromScreen ).
   top add:v.
   top open
