[comp.windows.interviews] Unidraw composite objects problem

mohr@i90s1.ira.uka.de (Thomas Mohr) (06/18/91)

I am using Unidraw with 3.0beta.

1) I found that GraphicComps does Picture::Append() during 
   GraphicComps::Append(); with the picture=graphic supplied
   to the constructor. Am I right that the application should *not*
   call Picture::Append() with the graphics he wants to
   have composed ? Instead, should he provide an empty Picture
   to the GraphicComps constructor ?

2) I have a GraphicComps with some GraphicComp inserted. I now want
   a command to change the position of one of the subgraphics. What
   I do right now is finding the Graphic and do a Translate() with it.
   I've tried some possibilities of informing Subjects and Views about
   the change. However, the output looks wierd, the positions are
   wrong. BUT: Cut & Paste gives me what I wanted to have: the
   subgraphics are well arranged. 

Any help is very appreciated !
