Hi,

I have the following code:


private void TestArrows() {

flowChart = new FlowChart();
this.getContentPane().add(flowChart);
flowChart.setMeasureUnit(GraphicsUnit.Pixel);
flowChart.setRouteArrows(false);

Box top = new Box(flowChart);
Box below1 = new Box(flowChart);
Box below2 = new Box(flowChart);
top.setObstacle(false);
below1.setObstacle(false);
below2.setObstacle(false);

below1.attachTo(top, AttachToNode.TopLeft);
below2.attachTo(top, AttachToNode.TopLeft);

top.setBounds(new Rectangle2D.Float(100, 100, 100, 100));
below1.setBounds(new Rectangle2D.Float(150, 250, 100, 100));
below2.setBounds(new Rectangle2D.Float(350, 250, 100, 100));
flowChart.add(top);
flowChart.add(below1);
flowChart.add(below2);

Arrow top1 = new Arrow(flowChart, top, below1);
Arrow top2 = new Arrow(flowChart, top, below2);
flowChart.add(top1);
flowChart.add(top2);

UpdateConnector(top, below1);
UpdateConnector(top, below2);
}

private void UpdateConnector(Box group, Box subordinate) {

// There will be only one connector
Arrow connector = subordinate.getIncomingArrows().get(0);
connector.getControlPoints().clear();

float midY = (subordinate.getBounds().y + group.getBounds().y + group.getBounds().height) / 2;

connector.getControlPoints().add(new Point2D.Float(group.getBounds().x + group.getBounds().width / 2, group.getBounds().y + group.getBounds().height));
connector.getControlPoints().add(new Point2D.Float(group.getBounds().x + group.getBounds().width / 2, midY));
connector.getControlPoints().add(new Point2D.Float(subordinate.getBounds().x + subordinate.getBounds().width / 2, midY));
connector.getControlPoints().add(new Point2D.Float(subordinate.getBounds().x + subordinate.getBounds().width / 2, subordinate.getBounds().y));

connector.setStyle(ArrowStyle.Cascading);

connector.updateFromPoints();
}

1. I have given the arrow a cascading feel and assigned 4 control points per arrow.

So, both arrows should appear with two bends, but when rendered, they come up with only 3 control points.

2. I can add the line flowChart.setArrowStyle(ArrowStyle.Cascading);
This will make the arrows come up with two bends. But on moving the top box, the second arrow loses its shape. How do I prevent this?

Thanks,
Praveen
