           Building a Constraint Based Graphical Editor for VODL

   Venue:   F013, UvA WINS
   Speaker: Harald Breebaart
   Title:   Building a Constraint Based Graphical Editor for VODL

   The  project is to create a graphical editor which allows the creation
   and  interactive  manipulation  of constraint-based graphical objects.
   These objects will typically be used for the visualisation of terms in
   an  algebraic  specifications environment. Implementation involves the
   use  of  a  constraint-  solver  and  a graphical user interface which
   communicate with each other through the toolbus.

   The editor will formulate the graphical (spatial) constraints in order
   to  use  the  solver for obtaining valid placement coordinates for the
   graphical  objects  it  contains.  The  GUI is being implemented using
   Python/Tk.  The  graphical  editor  is  being  designed  for use as an
   interactive tool for the picture definition language VODL.

   The  programming environment meetings are a forum for the presentation
   and  discussion  of  new  ideas,  ongoing and finished work. A typical
   meeting  addresses  a subject in the area of programming environments,
   program  generation, algebraic specification, term rewriting, parsing,
   etc.  A presentation ideally takes between 45 and 90 minutes. Meetings
   taking  longer  than 45 minutes are interrupted by a coffeebreak. Most
   Thursdays,  a  meeting is held which starts at 10:00 am. in one of the
   rooms at CWI/WINS. Exceptionally, dates or times may change.

   The    program    of    the    meetings    is    available   on   WWW:
