[glade--] Newbie Constructor problems

I'm trying to pass variables between windows, however I cannot seem to be able 
to create new constructors. For example:

class window_User : public window_User_glade
{
         public:
         window_User(string);

	private:
         void on_cut1_activate();
         void on_copy1_activate();
         void on_paste1_activate();
         void on_delete1_activate();
         void on_about2_activate();
         void on_calendar5_day_selected_double_click();
         void on_calendar5_next_month();
         void on_calendar5_prev_month();
         bool on_button_user_fetchcal_button_press_event(GdkEventButton *ev);
         bool on_button_user_updatecal_button_release_event(GdkEventButton 
*ev);
};

This gives me the following errors during compilation:

window_Login.o: In function `window_Login::on_button_login_login_pressed()':
/home/darkside/new/src/window_Login.cc:79: undefined reference to 
`window_User::window_User(std::basic_string<char, std::char_traits<char>, 
std::allocator<char> >)'
collect2: ld returned 1 exit status
make: *** [teamproject] Error 1

In window_Login class, I called:

window_User *window_User = new class window_User(legituser);
where legituser is a string.

Help is greatly appreciated, thank you.
