1. That returns a java.awt.Window, not org.apache.pivot.wtk.Window, so is not suitable for passing to Sheet#open. I guess I asked the question wrong -- I want a handle on the org.apache.pivot.wtk.Window that I opened at startup. Or does that make sense? The whole hosting-window thing I still find a bit unnatural. I guess I could do getDisplay().get(0) and cast it to a Window.
2. What if I'm not inside the code of a pivot component when I want access to the top-level window?
