on GMF graphic definition,you can define PolyLine ,but the line's location
and length is fixed.
so need use custom layout to set label's position and use custom border to
draw line and rectangle just like below:
public class CustomBorder extends LineBorder {
public void paint(IFigure figure, Graphics g, Insets insets) {
tempRect.setBounds(getPaintRectangle(figure, insets));
if (getWidth() % 2 == 1) {
tempRect.width--;
tempRect.height--;
}
tempRect.shrink(getWidth() / 2, getWidth() / 2);
g.setLineWidth(getWidth());
if (getColor() != null)
g.setForegroundColor(getColor());
g.drawRectangle(tempRect);
g.drawLine(tempRect.x +30, tempRect.y
tempRect.x + 30, tempRect.y + tempRect.height);
}
}

Thanks a lot bluetlck.
I can't purely rely on the GMF and code generation stuff, do I?
As I have seen from the previous post about graphic definition, GEF is
needed a lot.
Long way to go for my project. 8-]
