Here's the relevant portion of kparts/browserextension.h:

// KDE invents support for public signals...
#undef signals
#define signals public
signals:
#undef signals
#define signals protected

...

void createNewWindow( const KURL &url, const KParts::URLArgs &args,
                        const KParts::WindowArgs &windowArgs,   
                        KParts::ReadOnlyPart *&part );


The problem for PyKDE/sip is the reference to a pointer in the last argument.
There are a couple of issues here I'm not sure about, and need Phil's input 
on:

First, is it possible to write %MethodCode for a signal (even a "public" 
signal)? I seem to recall it wasn't possible, but there's always a good 
possibility my memory is wrong.

If not, then would it work to add some C++ to the sip file to connect to this 
signal (would require a special connect method to init the connection, I'd 
think) and then re-emit a signal, connect to an invented signal or call a 
method compatible with sip? Can I create a new signal in the sip file just by 
sticking a signal declaration in the %TypeHeader block and then referencing 
it like a normal signal in class block in the sip file?
