I guess I'm dense about how to subclass NSView -- do I do that via IB?
If so, How do I connect it to the NSView I placed in my main window?
Or is this simply a matter of putting the following in my controller
source --
public class myview extends NSView {
public void drawRect(NSRect rect) {
NSRect nr = new NSRect(0,0,40,40);
NSBezierPath BP = NSBezierPath.bezierPath();
NSColor.colorWithCalibratedRGB(1f, 0f, 0f, 0.5f).set();
BP.fillRect(nr);
}
}

Once you have subclassed the view, you need to override the drawRect

This will draw a transparent red rectangle in your view.
