Hi,
I need to draw a line across a figure. I used polyline but I was not able to
find the location of the figure in the clientarea. I need to draw a sort of
table inside the figure where in the user can drop other figures.
Any inputs.
Thanks in advance,
Dinesh

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
