NAME

       EllipseComp,  EllipseView,  PSEllipse  -  ellipse  component subject, view, and PostScript
       external representation

SYNOPSIS

       #include <Unidraw/Components/ellipse.h>

DESCRIPTION

       EllipseComp is a GraphicComp that defines an ellipse.  It uses an Ellipse graphic to store
       its  graphical  attributes.   EllipseView  is  a  GraphicView  for displaying the ellipse.
       PSEllipse is a PostScriptView that externalizes the subject's  information  in  PostScript
       form.

ELLIPSECOMP PUBLIC OPERATIONS

       EllipseComp(SF_Ellipse* = nil)
              The   constructor  takes  an  optional  stroked-filled  ellipse  that  defines  the
              attributes of the ellipse.

       SF_Ellipse* GetEllipse()
              Return the SF_Ellipse graphic that defines the ellipse's attributes.  GetEllipse is
              simply a more specific form of the GetGraphic operation.

ELLIPSEVIEW PUBLIC OPERATIONS

       EllipseView(EllipseComp* = nil)
              Create an EllipseView, optionally supplying the subject.

       virtual void Interpret(Command*)
              EllipseView interprets AlignToGridCmd to align its center to the grid.

       virtual Manipulator* CreateManipulator(
          Viewer*, Event&, Transformer*, Tool*
       )

       virtual void InterpretManipulator(Manipulator*)
              EllipseView  redefines  its  response  to manipulation with a GraphicCompTool.  The
              user clicks to specify the center of the ellipse and then drags to vary  its  axes.
              The center and the axes will be constrained by gravity, if any.

       EllipseComp* GetEllipseComp()
              Return the subject.

PSELLIPSE PUBLIC OPERATIONS

       PSEllipse(EllipseComp* = nil)
              Construct a PostScript external representation of the given subject, if any.
