I'm looking for a way of creating a Panel that can only be created once

What i did until now is to populate the panel in the register and check
if it exist or not and it work until the panel is close, i can't open it
anymore. I didn't find any informations about Pane closing callback that
could let me unregister it.
Or maybe there is an easiest way of doing?
You can create a singleton or use the Borg pattern. See:
