Thanks Wade,
I used the method to drag DrawGraphics into the form and it works great.
However there is now a new problem, which also must have a simple solution,
but I can't find it.
In the previous method under Eclipse when I changed the initialization I had
a jDraw whose value I knew.
Then to update the drawing was trivial:
jDraw.repaint();
Now the same jDraw is a private member of NMViewView and I don't know how to
cause it to repaint itself.
I defined an additional proceedure
public void repaintImages() {
jDraw.repaint();
}
which gets around the private definition of jDraw, but I am having
difficulty getting to the routine.
Somehow I have the feeling that it shouldn't be this difficult just to ask
it to repaint the panel.
