NAME

       PolygonComp, PolygonView, PSPolygon - polygon component subject, view, and PostScript external representation

SYNOPSIS

       #include <Unidraw/Components/polygon.h>

DESCRIPTION

       PolygonComp  is	a VerticesComp that defines a polygon.	It uses an SF_Polygon graphic to store its graphical attributes.  PolygonView is a
       VerticesView for displaying the polygon.  PSPolygon is a PSVertices that externalizes the subject's information in PostScript form.

POLYGONCOMP PUBLIC OPERATIONS

       PolygonComp(SF_Polygon* = nil)
	      The constructor takes an optional stroked-filled polygon graphic that defines the attributes of the polygon.

       SF_Polygon* GetPolygon()
	      Return the Polygon graphic that defines the polygon's attributes.  GetPolygon is simply a more specific form of the GetGraphic oper-
	      ation.

POLYGONVIEW PUBLIC OPERATIONS

       PolygonView(PolygonComp* = nil)
	      Create an PolygonView, optionally supplying the subject.

       virtual Manipulator* CreateManipulator(
	  Viewer*, Event&, Transformer*, Tool*
       )

       virtual void InterpretManipulator(Manipulator*)
	      PolygonView  redefines  its  response to manipulation with a GraphicCompTool.  The user clicks the left mouse button to specify each
	      vertex and clicks with the middle mouse button to specify the final vertex.  Vertex positioning will be constrained by  gravity,	if
	      any.   PolygonView  also	defines a response to the ReshapeTool, allowing the user to click on one of its vertices to reposition it.
	      The subject is actually replaced (via ReplaceCmd) with a new PolygonComp subject reflecting the repositioned vertex.   Repositioning
	      will be influenced by gravity.

       PolygonComp* GetPolygonComp()
	      Return the subject.

PSPOLYGON PUBLIC OPERATIONS

       PSPolygon(PolygonComp* = nil)
	      Construct a PostScript external representation of the given subject, if any.

PSPOLYGON PROTECTED OPERATIONS

       virtual const char* Name()
	      PSPolygon identifies itself as "Poly" in the PostScript output.

NAME

       PadComp, PadView, PadGraphic, PSPad - pad connector subject, view, structured graphic, and PostScript external representation

SYNOPSIS

       #include <Unidraw/Components/pad.h>

DESCRIPTION

       PadComp	is  a  Connector  subclass  that  supports  connectivity with two degrees of freedom.  It uses a PadGraphic to store its graphical
       attributes.  PadView is a GraphicView for displaying the pad.  PSPad is a PostScriptView that externalizes  the	subject's  information	in
       PostScript form.

PADCOMP PUBLIC OPERATIONS

       PadComp(PadGraphic* = nil)
	      The constructor takes an optional PadGraphic that defines the pad's graphical attributes.

       virtual void Interpret(Command*)
       virtual void Uninterpret(Command*)
	      PadComp  (un)interprets  a subset of commands that connectors can generally interpret, namely MoveCmd, BrushCmd, AlignCmd, Mobility-
	      Cmd, DeleteCmd, and CutCmd.

       virtual Mobility GetMobility()
       virtual void SetMobility(Mobility)
	      PadComp redefines these functions to return and assign its _mobility protected member.  The pad has fixed mobility initially.

       Pad* GetPad()
	      Return the Pad graphic that defines the line's attributes.  GetPad is simply a more specific form of the GetGraphic operation.

PADVIEW PUBLIC OPERATIONS

       PadView(PadComp* = nil)
	      Create an PadView, optionally supplying the subject.

       virtual void Interpret(Command*)
	      PadView interprets AlignToGridCmd to align its lower left to the grid.

       virtual Manipulator* CreateManipulator(
	  Viewer*, Event&, Transformer*, Tool*
       )

       virtual void InterpretManipulator(Manipulator*)
	      PadViews respond only to manipulation by GraphicCompTools, MoveTools, and ConnectTools. PadView inherits its MoveTool response  from
	      ConnectorView.   GraphicCompTool	will let the user sweep out a rectangle that reflects the pad's size.  Creation will be influenced
	      by gravity, if any. PadView creates a ConnectManip in response to the ConnectTool, which will exhibit a  gravational  attraction	to
	      potential  target  connectors.  PadView will produce a ConnectCmd to connect the pad to its target. A pad connected in this way will
	      receive floating mobility.

       PadComp* GetPadComp()
	      Return the subject.

PADVIEW PROTECTED OPERATIONS

       PadGraphic* GetPad()
	      Return the PadGraphic that defines the pad's attributes.	GetPad is simply a more specific form of the GetGraphic operation.

       virtual PadComp* NewSubject(PadGraphic*)
	      A helper function that creates a PadComp subject with the given pad graphic. This function produces  the	proper	subject  when  the
	      GraphicCompTool's manipulator is interpreted.  Subclasses can redefine this operation to return a PadComp subclass, thus eliminating
	      the need to reimplement InterpretManipulator.

       Manipulator* CreateGraphicCompManip(
	   Viewer*, Event&, Transformer*, Tool*
       )

       Manipulator* CreateConnectManip(
	   Viewer*, Event&, Transformer*, Tool*
       )

       Command* InterpretGraphicCompManip(Manipulator*)
       Command* InterpretConnectManip(Manipulator*)
	      Helper functions used by CreateManipulator and InterpretManipulator to create and interpret the manipulators associated with  Graph-
	      icCompTool and ConnectTool.

PADGRAPHIC PUBLIC OPERATIONS

       PadGraphic(
	   Coord = 0, Coord = 0, Coord = 0, Coord = 0,
	   Graphic* = nil
       )
	      Create  a PadGraphic, optionally specifying lower-left and upper-right corners and a graphic from which to obtain its default graph-
	      ics attributes.

       void GetOriginal(Coord&, Coord&, Coord&, Coord&)
	      Return the PadGraphic's original coordinates as specified in the constructor.

PSPAD PUBLIC OPERATIONS

       PSPad(PadComp* = nil)
	      Construct a PostScript external representation of the given subject, if any.
