Shape CanvasHxPolyline2d::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. 

00093 {
00094     int[] xp = getAddXCcs();
00095     int[] yp = getAddYCcs();
00096     GeneralPath path = new GeneralPath(GeneralPath.WIND_NON_ZERO, xp.length);
00097     path.moveTo(xp[0], yp[0]);
00098     for (int i=1 ; i < xp.length ; i++)
00099         path.lineTo(xp[i], yp[i]);
00100     return path;
00101 }

boolean CanvasHxPolyline2d::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.

00106     return true;
