XtCallActionProc searches for
the named action routine in the same manner and order as translation tables
are bound. If found, the action routine is invoked with the specified widget,
event pointer, and parameters. It is the responsibility of the caller to
ensure that the contents of event, params, and num_params arguments are
appropriate for the specified routine, and if necessary, that the specified
widget is realized or sensitive. If the named action routine cannot be found,
XtCallActionProc generates a warning message and returns.
