After that, when you do the gtk_signal_connect, it stores a *pointer* to the same memory area, like widget=button. And that pointer (widget) is sent as an argument to the callback. When you call: button=gtk_button_new_with_label("button2"); The "button" pointer now points to buttom2, but that doesn't destroy button1, only changes where "button" is pointing to. That way, each button's callback receives it's own widget pointer.
