Hi Rob,

The new file offapi/com/sun/star/scanner/XScannerManager2.idl is missing 
from the patch (I guess you did not git add it before you created the 
git diff).

Then, as Markus already pointed out, the ScannerManager class needs to 
be adapted, to derive from XScannerManager2.

Further, I noted that when configureScannerAndScan in scanunx.cxx calls 
the SaneDlg constructor, it should pass "listener.is()" instead of 
"(listener != NULL)" for bScanEnabled.  While the latter (happens to) 
work as well, the former is much cleaner and the preferred idiom when 
working with com::sun::star::uno::Reference.

And finally, the scanwin.cxx case does not support the new feature at 
all, right?  Then we should at least change the end of the changed line 
in that file from "const uno::Reference< lang::XEventListener >& 
rxListener )" to "const uno::Reference< lang::XEventListener >& )", to 
avoid warnings about unused parameters.  Better yet, the button should 
be hidden.  (Or even better yet, the new functionality should be 

If you provide the missing XScannerManager2.idl, I can tweak the above 
issues in the patch for you, if you like.
