So how do I prevent the inner document window from being closed?

Well, in fact the frame isn't closed, so there is no reason to ask your
listener for permission. There is only one frame object involved, this
object and its window are controlled by the "outer" (big) closer. The
"inner" closer (the smaller one) does not control a frame it removes the
component inside the frame from the frame. This feature was introduced
for the last frame (window) of OOo because it allows users to keep OOo
in memory without keeping their last document open.
//If i add the listener to the xcomponent, the queryClosing
method is fired when either the internal document's close button or the
frame's close button is clicked, but the document is not prevented from
closing
XCloseBroadcaster xc = (XCloseBroadcaster)xComponent;
xc.addCloseListener(new CloseListener());
No, it should be: usually closing the document window would also close
the document (means: destroy it) but this shouldn't happen if you
register your listener and veto against closing. Of course you can't
prevent the window from being closed here - in fact you can't do it at
all as I have to admit.
So here's what you should see in the listener you have registered at the
document (component):
- you get a queryClosing
- if you throw a CloseVetoException you shouldn't get any further calls
- if you don't object you should get a closing() as well as a
disposing() notification.
