PinComp, PinGraphic, PSPinSYNOPSIS
#include <Unidraw/Components/pin.h>DESCRIPTION
PinComp is a Connector subclass that supports connectivity with zero degrees of freedom. It uses a PinGraphic to store its graphical attributes. PinView is a GraphicView for displaying the pin. PSPin is a PostScriptView that externalizes the subject's information in PostScript form.SlidingPin and FixedPin are special rubberbands used to implement the animation effects that pins produce during direct manipulation. A SlidingPin is a circle with crosshairs (duplicating the appearance of a PinGraphic) that follows the mouse position, while a FixedPin draws a static circle with crosshairs.
PINCOMP PUBLIC OPERATIONS
- PinComp(PinGraphic* = nil)
- The constructor takes an optional PinGraphic that defines the pin's graphical attributes. The pad has fixed mobility initially
- virtual void Interpret(Command*)
- virtual void Uninterpret(Command*)
- PinComp (un)interprets a subset of commands that connectors can generally interpret, namely MoveCmd, BrushCmd, AlignCmd, MobilityCmd, DeleteCmd, and CutCmd.
- virtual Mobility GetMobility()
- virtual void SetMobility(Mobility)
- PinComp redefines these functions to return and assign its _mobility protected member. The pin has fixed mobility initially.
- Pin* GetPin()
- Return the Pin graphic that defines the line's attributes. GetPin is simply a more specific form of the GetGraphic operation.
PINVIEW PUBLIC OPERATIONS
- PinView(PinComp* = nil)
- Create an PinView, optionally supplying the subject.
- virtual void Interpret(Command*)
- PinView interprets AlignToGridCmd to align its lower left to the grid.
- virtual Manipulator* CreateManipulator(
- Viewer*, Event&, Transformer*, Tool*
- )
- virtual void InterpretManipulator(Manipulator*)
- PinViews respond only to manipulation by GraphicCompTools, MoveTools, and ConnectTools. PinView inherits its MoveTool response from ConnectorView. GraphicCompTool will let the user place the pin at a particular position. Placement will be influenced by gravity, if any. PinView creates a ConnectManip in response to the ConnectTool, which will exhibit a gravational attraction to potential target connectors. PinView will produce a ConnectCmd to connect the pin to its target. A pin connected in this way will receive floating mobility.
- PinComp* GetPinComp()
- Return the subject.
PINVIEW PROTECTED OPERATIONS
- PinGraphic* GetPin()
- Return the PinGraphic that defines the pin's attributes. GetPin is simply a more specific form of the GetGraphic operation.
- virtual PinComp* NewSubject(PinGraphic*)
- A helper function that creates a PinComp subject with the given pin graphic. This function produces the proper subject when the GraphicCompTool's manipulator is interpreted. Subclasses can redefine this operation to return a PinComp 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 GraphicCompTool and ConnectTool.
PINGRAPHIC PUBLIC OPERATIONS
- PinGraphic(Coord = 0, Coord = 0, Graphic* = nil)
- Create a PinGraphic, optionally specifying its center and a graphic from which to obtain its default graphics attributes.
- void GetOriginal(Coord&, Coord&)
- Return the PinGraphic's original center coordinates as specified in the constructor.
PSPIN PUBLIC OPERATIONS
- PSPin(PinComp* = nil)
- Construct a PostScript external representation of the given subject, if any.
