Equivalent to Xt translation manager (XtAppAddActions() etc.)?

[Toralf Lund <toralf procaptura com>]

Does Gtkmm/Gtk/GDK have an equivalent to XtAppAddActions()/the Xt 
translations manager?

What the translation manager does is, and I quote,

   The Xt translation manager calls an action routine when an event
   sequence matches an event specification in a widget translation
   table. In a translation table, actions are associated with event
   specifications. More than one event sequence can invoke the same
   action routine.
