Can anyone tell me the differences between Windows.detach() and Windows.invalidate(). Which method should be used to forcibly make the component eligible for Garbage Collection?

Thanks

.invalidate() -> forces to refresh/reDraw/rePaint the component.
.detach -> cut the component from the page, so it's not more in the DOM and can be free.

Thanks. So if we detach the window, will all the components under that window will be the candidate for garbage collection?
