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

       PolygonComp, PolygonView, PSPolygon - polygon component subject, view, and PostScript external representation

SYNOPSIS

       #include <Unidraw/Components/polygon.h>

DESCRIPTION

       PolygonComp  is	a VerticesComp that defines a polygon.	It uses an SF_Polygon graphic to store its graphical attributes.  PolygonView is a
       VerticesView for displaying the polygon.  PSPolygon is a PSVertices that externalizes the subject's information in PostScript form.

POLYGONCOMP PUBLIC OPERATIONS

       PolygonComp(SF_Polygon* = nil)
	      The constructor takes an optional stroked-filled polygon graphic that defines the attributes of the polygon.

       SF_Polygon* GetPolygon()
	      Return the Polygon graphic that defines the polygon's attributes.  GetPolygon is simply a more specific form of the GetGraphic oper-
	      ation.

POLYGONVIEW PUBLIC OPERATIONS

       PolygonView(PolygonComp* = nil)
	      Create an PolygonView, optionally supplying the subject.

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

       virtual void InterpretManipulator(Manipulator*)
	      PolygonView  redefines  its  response to manipulation with a GraphicCompTool.  The user clicks the left mouse button to specify each
	      vertex and clicks with the middle mouse button to specify the final vertex.  Vertex positioning will be constrained by  gravity,	if
	      any.   PolygonView  also	defines a response to the ReshapeTool, allowing the user to click on one of its vertices to reposition it.
	      The subject is actually replaced (via ReplaceCmd) with a new PolygonComp subject reflecting the repositioned vertex.   Repositioning
	      will be influenced by gravity.

       PolygonComp* GetPolygonComp()
	      Return the subject.

PSPOLYGON PUBLIC OPERATIONS

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

PSPOLYGON PROTECTED OPERATIONS

       virtual const char* Name()
	      PSPolygon identifies itself as "Poly" in the PostScript output.
