glade-- will not change your class declaration (design decision), but 
the file dialog.hh_new will contain new declarations. Please cut and 
paste them into dialog.hh.

This simply means that the function you declared is not compatible with 
gtkmm's idea of a matching callback.

This might be an error with glade--'s default code generation since 
correct callback arguments made it's way into glade-- very shortly.

If I interpret this message right the signal should return a gboolean.

Perhaps you connected to delete_event ? (I can only guess)

Please read the glade-- user manual. It should cover the first problem.
