The ObjectExplorer is a GUI window that you can embed in your program and instantiate at any time to provide interactive browsing and inspection of the objects in your program.

See discussion at  /forums/viewtopic.php?f=4&t=563

For a non-interactive dump of objects, especially in response to an exception, use the DetailedStackTrace.
