thanks a lot..
I think passing the main object only by reference.. so, this does not causes
any overhead..
am i correct..?

Please suggest me right direction.. and tell me how to do it?

Thanks for any advice....
Most of the widget classes in your code should be derived classes, so they
can hold extra instance data & event handlers and such. So that means you
can have extra parameters on the constructor, besides the ones the base
class requires. Use one or more of those extra parameters to store your own
information about the hierarchy.
Simplest example is to add the app instance to each constructor. Then each
widget object would know how to call back into the app to do some work, or
to load data into a common place.

All objects are passed by reference in python. And storing it in each widget
costs very little. Note that you can choose what object or objects should be
used; I just mention the app as a choice that everyone will subclass, and that
will generally have direct or indirect access to all widgets.
