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.
