RE: [gtkmm] Overloading on_response() member of a Dialog object.

[Jean-Luc Bedwani <jlbedwani imascope ca>]

I finally decided to go with a Gtk::Window  instead of a Gtk::Dialog.
Since I've never been able to mask the signal emission for certain
button of the dialog box, I created my own window with a set of events
that i can connect to from my main application window.
