A signal for Gtk::MessageDialog

["Jamiil Abduqadir" <jalqadir gmail com>]

Hello,
I am writing a class that derives from 'Gtk::MessageDialog'. What does the class do? you got it, it displays a dialog box with some information on it. Now, to the problem. Just like any 'Gtk::MessageDialog' it has a button in there that I need to connect to a signal, but since I don't know the name of the button, I cannot write something like
Mybutton.signal_clicked().connect(sigc::ptr_fun(&on_button_clicked));

What can I do to find the object name of Gtk::Button in the Gtk::MessageDialog?


------snip------
namespace jme{
class GtkmmException : public virtual Gtk::MessageDialog{ 
private:
jme::Exception* ex;

protected:
public:
GtkmmException(Glib::ustring&, jme::Exception&);

~GtkmmException();

virtual void btnClicked();
}; // class
} 

jme::GtkmmException::GtkmmException( Glib::ustring& str, jme::Exception& e)
: Gtk::MessageDialog(str){
   try{ex = new jme::Exception();}
   catch(std::bad_alloc& x){ std::cout << 
x.what(); exit(-1);   }
   ex->copy(e);

   Gtk::MessageDialog::set_moday(true);

   Is this right?
  ~~~~~~~~~~
  this->signal_clicked().connect( sigc::mem_fun(*this,
   &GtkmmException::btnClicked) );
}
//void jme::GtkmmException::btnClicked(){/*Initiate atomic reactor, hihihi*/}

jme::GtkmmException::~GtkmmException(){ delete ex;}
