When we call any of these two methods of WindowControl interface
 void removeFocus()                  
 void setFocus() 
and try to catch the events by regestring event listeners in JavaScript
e.g. window.addEventListener("focus", onFocusGained, false))
in the preliminarily loaded page it doesn't work (no events are caught).
Supposed reason: Even support is unimplemented yet, so code must thrown a

SetFocus funtion in WindowControl calls into the Mozilla
nsIBaseWindow->SetFocus() function. If there is a disconnect here, it is most
probably because something here was broken in the embedding APIs (that gave
access to nsIBaseWindow object) at the time M16 was released.

RemoveFocus - support for this was removed from M15 onwards. Hence there is no
Embedding API by which this functionality can be exposed to the Webclient users.
I will make this throw an UnImplementedException and check in the change. Will
also follow up with Mozilla Embedding folks to find out if this functionality
might come back later.

Checked patch into cvs that throws UnImplementedException. I wont close this Bug
as yet. After we sync up with the PR3 branch, I'll check if this persists...and
only then will I close/work on this bug.

I have changed WindowControlImpl.java so that it calls into Native code 
(nsIBaseWindow->SetFocus)when SetFocus is called (instead of throwing 
UnImplementedException). I have also changed the comment in the Exception 
thrown when RemoveFocus is called to indicate that RemoveFocus is no longer 
supported by Mozilla. This function does not make much sense anyways 
considering that SetFocus is provided to Embedders who wish to have the ability 
to TAB through the page being displayed. We should seriously consider removing 
this Function from the API.

QA, pls test whether SetFocus works with your API tests using the 
Netscape6_0_OEM_Branch mozilla codebase. I know this didn't work with M16. 

Ed, do I have ra=edburns for checking this in?

SetFocus seems to work and RemoveFocus is no longer supported in Gecko 
Embedding. Would the reporter pls verify that the SetFocus works. I am closing 
this Bug.
