Client area is the region in which children figures are placed. If you are
painting the actual parent figure itself, you should use it's bounds,
cropped by its insets. Most of the time these two Rectangle will be the
same, but if your figure uses local coordinates, they are different.
protected void paintFigure(Graphics g) {
Rectangle r = getBounds().getCropped(getInsets());
//Draw a plus sign inside the figure.
g.drawLine(r.getLeft(), r.getRight());
g.drawLine(r.getTop(), r.getBottom());
}

Randy,
Thanks for the reply. I am drawing the line inside Figure. It doesnt have a
method drawline.
My code is
IFigure fig = new Figure();
fig.setOpaque(true);
fig.setBackgroundColor(ColorConstants.lightGray);
fig.setLayoutManager(new FreeformLayout());
Polyline line=new Polyline(); //This is the line I like to draw inside the
figure
line.setParent(fig);
Rectangle r = fig.getBounds().getCropped(fig.getInsets());
line.setEndpoints(r.getLeft(),r.getRight());
line.setForegroundColor(ColorConstants.black);
line.setLineWidth(200);
line.setFill(true);
line.setLayoutManager(new FreeformLayout());
Thanks,
Dinesh

Randy,
I got it working now. I override the figure class and now it is working.
Thanks,
Dinesh
