.TH EllipseComp 3U "22 January 1991" "Unidraw" "InterViews Reference Manual" .SH NAME EllipseComp, EllipseView, PSEllipse \- ellipse component subject, view, and PostScript external representation .SH SYNOPSIS .B #include .SH 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. .SH ELLIPSECOMP PUBLIC OPERATIONS .TP .B "EllipseComp(SF_Ellipse* = nil)" The constructor takes an optional stroked-filled ellipse that defines the attributes of the ellipse. .TP .B "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. .SH ELLIPSEVIEW PUBLIC OPERATIONS .TP .B "EllipseView(EllipseComp* = nil)" Create an EllipseView, optionally supplying the subject. .TP .B "virtual void Interpret(Command*)" EllipseView interprets AlignToGridCmd to align its center to the grid. .TP .B "virtual Manipulator* CreateManipulator(" .ns .TP .B " Viewer*, Event&, Transformer*, Tool*" .ns .TP .B ")" .ns .TP .B "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. .TP .B "EllipseComp* GetEllipseComp()" Return the subject. .SH PSELLIPSE PUBLIC OPERATIONS .TP .B "PSEllipse(EllipseComp* = nil)" Construct a PostScript external representation of the given subject, if any. .SH SEE ALSO GraphicComp(3U), GraphicCompTool(3U), GraphicView(3U), Grid(3U), PostScriptView(3U), align(3U), ellipses(3U)
