SWT does not support this yet. The DOT style is 3 pixels long. If you
overlay two of them with XOR, you can get 1 pixel appearance.

I think that it's possible since SWT 3.1m5; there is a new
SWT.LINE_CUSTOM style )))

Hi,Randy
I tried as your advice, but setXOR(true) seems not working the right way.
I use a Polyline, the following is my code:
public class myFigure extends Polyline
{
public myFigure()
{
super();
/**
* Polyline
*/
setLineStyle(Graphics.LINE_DOT);
setLineWidth(1);
Point point1 = new Point(0,100);
Point point2 = new Point(100,100);
setEndpoints(point1,point2);
setForegroundColor(ColorConstants.blue);
Polyline pl = new Polyline();
pl.setLineStyle(Graphics.LINE_DOT);
pl.setLineWidth(1);
pl.setEndpoints(new Point(1,100),new Point(101,100));
pl.setForegroundColor(ColorConstants.blue);
add(pl);
}
......
}
Then, In editpart:
myFigure figure = new myFigure();
figure.setXOR(true);
BUT the result is not what I want!
I don't think I'm right here, but I really don't know how to.
Can u please advice more or point out the wrong thing?
Thanks in advance
BR,
zbw

Look at GuideLineFigure. Also, make sure you don't run into these bugs:
