rectangle without border

Question

In draw2d,How can I draw a figure without having any border? How to implements the CustomBorder for rectangles to remove the border? I know if we implement a class which extends Border, and in the paint method what should I do to remove the border?

Answer 1

Figures don't have a border unless you explicitly set one by calling setBorder(..). If you just want a blank figure that doesn't draw anything, then new Figure() will give you just that. There's no need to implement any custom borders or figures. If you are using a Rectangle then that's exactly what you will get: a rectangle; which is what you probably confused for a border.

Answer 2

You can disable the border with figure.setBorder(null); or you can put it in the constructor:

public static  class BorderlessFigure extends Figure {
    public BorderlessFigure() {
        ToolbarLayout layout = new ToolbarLayout();
        setLayoutManager(layout);   
        setBorder(null);
        add(new Label("test"));  
    }
}

If you want a Border that does not paint anything you can extend org.eclipse.draw2d.AbstractBorder:

public class NoBorderBorder extends AbstractBorder {
    @Override
    public void paint(IFigure f, Graphics g, Insets i) { }

    @Override
    public Insets getInsets(IFigure f) {
        return new Insets(0);
    }
}

I don't know why would you do that though.
