RectComp, RectView, PSRect - rectangle component subject, view, and PostScript external representation
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.
RECTCOMP PUBLIC OPERATIONS
RectComp(SF_Rect* = nil) The constructor takes an optional stroked-filled rectangle that defines the attributes of the rectangle. 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.
RECTVIEW PUBLIC OPERATIONS
RectView(RectComp* = nil) Create an RectView, optionally supplying the subject. virtual void Interpret(Command*) RectView interprets AlignToGridCmd to align its lower-left to the grid. virtual Manipulator* CreateManipulator( Viewer*, Event&, Transformer*, Tool* ) 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. 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. RectComp* GetRectComp() Return the subject.
RECTVIEW PROTECTED OPERATIONS
virtual void CreateHandles() RectView redefines CreateHandles to use a RubberHandles object with four handles, one at each corner of the rectangle.
PSRECT PUBLIC OPERATIONS
PSRect(RectComp* = nil) Construct a PostScript external representation of the given subject, if any.
