public static interface IlvManagerView.FitAreaCalculator
IlvManagerView.fitTransformerToArea(Insets, FitAreaCalculator, int)
.
The following example shows how to make all selected objects visible in the view by using this interface:
IlvManagerView.FitAreaCalculator fcalc = new IlvManagerView.FitAreaCalculator() { public IlvRect getAreaToFit(IlvManagerView view) { IlvGraphicEnumeration e = view.getManager().getSelectedObjects(true); IlvRect rect = null; while (e.hasMoreElements()) { IlvGraphic g = e.nextElement(); IlvManager m = (IlvManager)g.getGraphicBag(); IlvRect bbox = g.boundingBox(m.getDrawingTransformer(view)); if (rect == null) rect = bbox; else rect.add(bbox); } if (rect == null) // nothing selected, fallback: fit to all return view.computeBBox(); else return rect; } }; managerView.fitTransformerToArea(null, fcalc, 10);
