Creates a new IlvGraphicDecoration object displaying the specified graphic object centered within the plot area.

Parameters:

graphic - The graphic object to display.

IlvGraphicDecoration

public IlvGraphicDecoration(IlvGraphic graphic,
                            int anchor)

Creates a new IlvGraphicDecoration object displaying the specified graphic object.

Parameters:

graphic - The graphic object to display.

anchor - The decoration's position within the plot area. One of the SwingConstants.CENTER, SwingConstants.NORTH, SwingConstants.NORTH_WEST, SwingConstants.WEST, SwingConstants.SOUTH_WEST, SwingConstants.SOUTH, SwingConstants.SOUTH_EAST, SwingConstants.EAST, SwingConstants.NORTH_EAST constants.

addObject

public void addObject(IlvGraphic graphic,
                      boolean redraw)

reDrawRegion

public void reDrawRegion(IlvRegion region)

Redraws a region of the bag.

Specified by:

reDrawRegion in interface IlvGraphicBag

Parameters:

region - The region to redraw.

reshapeObject

public void reshapeObject(IlvGraphic graphic,
                          IlvRect newrect,
                          boolean redraw)

newrect - The new desired bounding rectangle.

redraw - If true the object is redrawn.

moveObject

public void moveObject(IlvGraphic graphic,
                       double x,
                       double y,
                       boolean redraw)

Changes the location of a graphic object.

moveObject in interface IlvGraphicBag

Parameters:

graphic - The graphic object.

x - The new desired x position.

y - The new desired y position.

redraw - If true the object is redrawn.

applyToObject

public void applyToObject(IlvGraphic graphic,
                          IlvApplyObject f,
                          Object arg,
                          boolean redraw)

Applies a method to a graphic object of the bag. Every implementation of IlvGraphicBag.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean) must call IlvGraphic.setInApplyToObject(boolean) in the following way:

 public void applyToObject(IlvGraphic obj,
                           IlvApplyObject f, Object arg,
                           boolean redraw)
 {
   obj.setInApplyToObject(true);
   try {
     ...
   } finally {
     obj.setInApplyToObject(false);
   }
 }
 

If an IlvGraphic implements the IlvGraphicBag interface, the implementation can be done in the following way:

 public void applyToObject(IlvGraphic obj,
                           IlvApplyObject f, Object arg,
                           boolean redraw)
 {
   boolean needsRecursion = obj.setInApplyToObject(true);
   try {
     if (needsRecursion && getGraphicBag() != null) {
       final IlvGraphic fobj = obj;
       final IlvApplyObject ff = f;
       getGraphicBag().applyToObject(this, new IlvApplyObject() {
          public void apply(IlvGraphic thisObj, Object arg) {
            doSomething(fobj, ff, arg, false);
          }
       }, arg, redraw);
     } else {
       doSomething(obj, f, arg, redraw);
     }
   } finally {
     obj.setInApplyToObject(false);
   }
 }
