Display widget hierarchy in a gtkmm application

[Raj Kiran Grandhi <grkiran gmail com>]

Hi,

This may be asking for too much, but is there any way of determining
the widget hierarchy in a gtkmm (or gtk for that matter) application?
By widget hierarchy, I mean somthing like the widget tree display in
glade. Is there any command which can do this?

Thanks and regards,
Rajkiran
