.SH NAME
RectComp, RectView, PSRect \- rectangle component subject,
view, and PostScript external representation
.SH SYNOPSIS
.B #include <Unidraw/Components/rect.h>
.SH DESCRIPTION
RectComp is a GraphicComp that defines a rectangle.  It uses an
SF_Rect graphic to store its graphical attributes.  RectView is a
GraphicView for displaying the rectangle.  PSRect is a PostScriptView
that externalizes the subject's information in PostScript form.
.SH RECTCOMP PUBLIC OPERATIONS
.TP
.B "RectComp(SF_Rect* = nil)"
The constructor takes an optional stroked-filled rectangle that defines
the attributes of the rectangle.
.TP
.B "SF_Rect* GetRect()"
Return the SF_Rect graphic that defines the rectangle's attributes.
GetRect is simply a more specific form of the GetGraphic operation.
.SH RECTVIEW PUBLIC OPERATIONS
.TP
.B "RectView(RectComp* = nil)"
Create an RectView, optionally supplying the subject.
.TP
.B "virtual void Interpret(Command*)"
RectView interprets AlignToGridCmd to align its lower-left 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*)"
RectView redefines its response to manipulation with a
GraphicCompTool. GraphicCompTool will let the user sweep out a
rectangle that reflects the RectComp's size.  Creation will be
influenced by gravity, if any. RectView also defines a response to the
ReshapeTool, allowing the user to click on one of its corners to
reposition it.  The subject is actually replaced (via ReplaceCmd) with
a PolygonComp subject reflecting the repositioned corner.  Repositioning
will be influenced by gravity.
.TP
.B "virtual void GetCorners(Coord*, Coord*)"
GetCorners takes two arrays of four Coord values and stores into them
the coordinates of its corners, in canvas coordinates.
.TP
.B "RectComp* GetRectComp()"
Return the subject.
.SH RECTVIEW PROTECTED OPERATIONS
.TP
.B "virtual void CreateHandles()"
RectView redefines CreateHandles to use a RubberHandles object with
four handles, one at each corner of the rectangle.
.SH PSRECT PUBLIC OPERATIONS
.TP
.B "PSRect(RectComp* = nil)"
Construct a PostScript external representation of the given subject,
if any.
