Dojo widget for displaying connection status

in my dojo web app, I would like to display the 开发者_Python百科connection status through a red / green light, possibly circular like a traffic light. Is there anybody who knows an existing widget for the purpose?

AFAIK, there is no such widget existing yet. You can create your own widget. It's not a hard task to do that. Just use two different images to represent the state.
