Member Function Documentation

String CanvasHxSampledBSplineCurve::getSaName (    )  [inline]

Overrides CanvasObject interface. Reimplemented from CanvasObject. { return _name; }

void CanvasHxSampledBSplineCurve::setShowControlPoly (  boolean    b )  [inline]

{ _showControlPoly = b; }

String CanvasHxSampledBSplineCurve::getCPoly (    )  [inline]

{ String[] args = new String[0]; return _mediator.callMethod("HxSampledBSplineCurve", _name, "CPoly", "", args); }

String CanvasHxSampledBSplineCurve::getControlP (    )  [inline]

{ String[] args = new String[0]; return _mediator.callMethod("HxSampledBSplineCurve", _name, "controlP", "", args); }

Vector CanvasHxSampledBSplineCurve::getVisualChangeMethods (    )  [inline]

Overrides CanvasObject interface. Extends the list of callable functions obtained from the parent with the functions for this class. Reimplemented from CanvasFigure. { Vector v = super.getVisualChangeMethods(); v.add(new CallableMethod("setShowControlPoly", "boolean", "b", "boolean")); return v; }

Shape CanvasHxSampledBSplineCurve::getShape (    )  [inline, protected, virtual]

Derived classes have to implement this method to supply the shape that represents the CanvasFigures. It is used to draw to figure as well as determine which figure is selected (hit) by the cursor within a canvas. Reimplemented from CanvasFigure. { // first do the curve itself int[] xp = getAddXCcs(); int[] yp = getAddYCcs(); GeneralPath curve = new GeneralPath(GeneralPath.WIND_NON_ZERO, xp.length); curve.moveTo(xp[0], yp[0]); for (int i=1 ; i < xp.length ; i++) curve.lineTo(xp[i], yp[i]); // Then check whether control polygon should be visualized if (_showControlPoly) { int[] ccsX = new int[_cpX.length]; Converter.ICStoCCS(_cpX, ccsX, getZoomFactor()); int[] ccsY = new int[_cpY.length]; Converter.ICStoCCS(_cpY, ccsY, getZoomFactor()); GeneralPath cp = new GeneralPath(GeneralPath.WIND_NON_ZERO, _cpX.length); cp.moveTo(ccsX[0], ccsY[0]); for (int i=1 ; i < ccsX.length ; i++) cp.lineTo(ccsX[i], ccsY[i]); curve.append(cp, false); } return curve; }

boolean CanvasHxSampledBSplineCurve::hitOnStroke (    )  [inline, protected, virtual]

Derived classes have to implement this method to indicate whether they are selected (hit) based on their stroke (border) or on their interior. Reimplemented from CanvasFigure. { return true; }
