GraphicCompTool(3U) InterViews Reference Manual GraphicCompTool(3U)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.

EllipseComp(3U) InterViews Reference Manual EllipseComp(3U)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.
