If i understand you correctly, you need to run
someWidget.signal_size_allocate().emit(p); where someWidget is an
instance of your widget and p is a Gtk::Allocation object.

When i try what you told, i get the following error message:

'class Glib::SignalProxy1<void, Gtk::Allocation&>' has no member named 'emit'

Standard gtkmm signals wrap existing GTK+ signals. They don't offer a
way to emit them because this is generaly not a good idea.

If you must then you can use the regular C API to emit the underlying C
signal. Sometimes there is a C function that emits the specific signal,
sometimes doing extra checks.  

It's generally impossible to say if emitting a particular GTK+ signal is
a good idea without knowing more about what you are doing.
