Hi,

There are some instances when the head of an arrow disappears.

[code]


public class Goop extends JApplet {
private static final long serialVersionUID = 1L;

@Override
public void init() {
super.init();

flowChart = new FlowChart();
initialize();
testArrow();
//resizeTest();
}

private void initialize() {
flowChart = new FlowChart();
JScrollPane pane = new JScrollPane(flowChart);
this.getContentPane().add(pane);

flowChart.setSelectionOnTop(false);

flowChart.setArrowStyle(ArrowStyle.Cascading);
flowChart.setRouteArrows(true);
flowChart.getRoutingOptions().setTriggerRerouting(
RerouteArrows.WhileCreating | RerouteArrows.WhenModified);

flowChart.setMeasureUnit(GraphicsUnit.Pixel);

TextFormat textFormat = new TextFormat(Align.Center, Align.Near);
textFormat.setWrapAtCharacter(true);
flowChart.setTextFormat(textFormat);
}

private void testArrow() {
Box one = new Box(flowChart);
one.setBounds(new Rectangle2D.Float(10, 10, 100, 100));

Box two = new Box(flowChart);
two.setBounds(new Rectangle2D.Float(10, 160, 100, 100));

flowChart.add(one);
flowChart.add(two);

Arrow con = new Arrow(flowChart, one, two);
con.setArrowHead(ArrowHead.Triangle);
con.setArrowHeadSize(15);
con.setSnapToNodeBorder(true);
flowChart.add(con);
}
}
[/code]

If you just run the above code, you will see that the arrow head is missing (which I have specified as a triangle).

If you drag the lower box to the right, the head shows up.

In this scenario, when the two boxes are connected by a straight line, the box disappeared.

But sometimes, there are other scenarios as well when this happened.

Is there a way this can be stopped?

Thanks,
Praveen

Hi Stoyan,

This works, thank you.

I would also like to know if this would be required for the arrowBase calculation in updateArrowHeads method.

I appreciate your prompt replies to my posts.

Thank you,
Praveen
