Is it possible to reference a datawindow object in a datawindow?

My scenario :

I have a datawindow (composite) which holds another datawindow (nested
report).
This child datawindow has a OLE ActiveX object which I am trying to access
from the window which holds the composite datawindow.

The reason for this is because I need to access the ActiveX
properties/functions after the composite datawindow have been retrieved.

I've tried to get a reference to the child datawindow :

//DataWindowChild dwc_activex
dw1.getchild("dw_activex", dwc_activex)

But as datawindowchild object does not support this syntax:

dwc_activex.object.ole_1.object.load(setting.txt)

Am I facing the limits of the what can be done with datawindows here?
