I thought you had preset the Graphics_Tree property of the clipboard
instance, eg using:
myClipboard = obj_new('IDLgrClipBoard', GRAPHICS_TREE = myView)
or:
myClipboard->SetProperty, GRAPHICS_TREE = myView
However I have a feeling I'm about to find out why that is not a good idea!
(i.e. am I right in thinking that if you destroy the clipboard object after
attaching the view object then
you lose that graphic object?)
