Represents an event cause by user's openning or closing something at the client.

Note: it is a bit confusing but Events.ON_CLOSE is sent when user clicks a close button. It is a request to ask the server to close a window, a tab or others. If the server ignores the event, nothing will happen at the client. By default, the component is detached when receiving this event.

On the other hand, Events.ON_OPEN (with OpenEvent) is a notification. It is sent to notify the server that the client has opened or closed something. And, the server can not prevent the client from opening or closing.
