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

       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.
