NAME

       RectComp,  RectView,  PSRect  - rectangle component subject, view, and PostScript external
       representation

SYNOPSIS

       #include <Unidraw/Components/rect.h>

DESCRIPTION

       RectComp is a GraphicComp that defines a rectangle.  It uses an SF_Rect graphic  to  store
       its graphical attributes.  RectView is a GraphicView for displaying the rectangle.  PSRect
       is a PostScriptView that externalizes the subject's information in PostScript form.

RECTCOMP PUBLIC OPERATIONS

       RectComp(SF_Rect* = nil)
              The constructor  takes  an  optional  stroked-filled  rectangle  that  defines  the
              attributes of the rectangle.

       SF_Rect* GetRect()
              Return  the  SF_Rect  graphic  that defines the rectangle's attributes.  GetRect is
              simply a more specific form of the GetGraphic operation.

RECTVIEW PUBLIC OPERATIONS

       RectView(RectComp* = nil)
              Create an RectView, optionally supplying the subject.

       virtual void Interpret(Command*)
              RectView interprets AlignToGridCmd to align its lower-left to the grid.

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

       virtual void InterpretManipulator(Manipulator*)
              RectView  redefines  its  response  to   manipulation   with   a   GraphicCompTool.
              GraphicCompTool  will  let  the  user  sweep  out  a  rectangle  that  reflects the
              RectComp's size.  Creation will be influenced by gravity,  if  any.  RectView  also
              defines  a  response  to  the ReshapeTool, allowing the user to click on one of its
              corners to reposition it.  The subject is actually replaced (via ReplaceCmd) with a
              PolygonComp  subject  reflecting  the  repositioned  corner.  Repositioning will be
              influenced by gravity.

       virtual void GetCorners(Coord*, Coord*)
              GetCorners takes two  arrays  of  four  Coord  values  and  stores  into  them  the
              coordinates of its corners, in canvas coordinates.

       RectComp* GetRectComp()
              Return the subject.

RECTVIEW PROTECTED OPERATIONS

       virtual void CreateHandles()
              RectView  redefines  CreateHandles to use a RubberHandles object with four handles,
              one at each corner of the rectangle.

PSRECT PUBLIC OPERATIONS

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