Examples of jsky.navigator.Navigator$NavigatorImageLoader

jsky.navigator.Navigator
This local class is used to load an image in the event dispatching thread. Doing it in the calling thread could cause the window to hang, since it needs to create and show a top level window and the calling thread (from CatalogNavigator) is already a background thread. The url is only needed for the image history, in case the file is deleted.
