NAME

       GraphicCompTool - tool for instantiating graphical components

SYNOPSIS

       #include <Unidraw/Tools/grcomptool.h>

DESCRIPTION

       A  GraphicCompTool  lets the user instantiate graphical components by direct manipulation.  The GraphicCompTool keeps a prototypical compo-
       nent that defines the type of component it can instantiate.

PUBLIC OPERATIONS

       GraphicCompTool(ControlInfo*, GraphicComp* prototype)
       GraphicCompTool()
	      Create a new GraphicCompTool, supplying the prototypical GraphicComp.  (You should not normally call the parameterless  constructor,
	      which Creator requires.)	The first constructor creates a graphical view of the prototype for internal use.

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

       virtual void InterpretManipulator(Manipulator*)
	      CreateManipulator  clears  the editor's selection and delegates manipulator creation and interpretation to the graphical view of the
	      prototype.

       GraphicComp* GetPrototype()
	      Return the prototypical GraphicComp.

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 Graph-
       icView 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 opera-
	      tion.

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 Poly-
	      gonComp 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.
