[delphi-en] Communicating with the MDIForom from a MDI Child of a Child

[kenhaile]

Greetings -

I want to send data and execute methods on an MDIForm from a
MDIChild-of-a-MDIChild WITHOUT having to include the MDIForm in the
uses clause of the MDIChild-of-a-MDIChild.  For example, how can I do
the following:

An MDIForm has a method named SetTable.  This method stores the name
of a table in a public variable named CurrentTable.

Another form, MDIChild2, is a descendant of MDIChild1.   I'd like to
set the variable CurrentTable found in MDIForm from MDIChild2.  I know
that I can include the MDIForm in the uses clause of MDIChild2.  But,
I'm curious how to do this using an object-oriented call.

MDIChild2 --> MDIChild1 --> MDIForm(CurrentTable)

Thanks in advance for your help :)
