To implement this with a WindProc, instead of passing the LCL self to the GTK object, instead pass the xxxCallbackInterface self to the object.  The xxxCallbackInterface has the LCL object Self stored.  Interfaces It takes the GTK callback information and instead of retrieving the LCL self, it instead gets the xxxCallbackInterface self.  From there, it calls a Transmit message routine, which reformats the callback data to an LCL message, and then calls the LCL Self WindProc.  This WindProc then calls Dispatch.

This would give each LCL component its own WindProc, and only replace the LCL self with a new xxxCallbackInterface self in the GTK callbacks.  Two additional layer of redirection, I suppose, the xxxCallbackInterface and the WindProc itself.

Is this not possible?  What am I missing?

That gets you to the opposite of my first attempt at making Win32 look like GTK.  There, I had one "true" (in the Win32 sense) WindProc.  I can tell you from the other side, this is definitely -NOT- the way to go.
