XtActionHookProc()					    XtActionHookProc()

Name
  XtActionHookProc - interface definition for action hook procedure.

Synopsis
  typedef  void	 (*XtActionHookProc)(Widget,  XtPointer, String, XEvent*,
  String*, Cardinal*);
	 Widget w;
	 XtPointer client_data;
	 String action_name;
	 XEvent* event;
	 String* params;
	 Cardinal* num_params;

Inputs
  w	    Specifies the widget whose action is about to be dispatched.

  client_data
	    Specifies data that was registered with this procedure  in	a
	    call to XtAppAddActionHook().

  action_name
	    Specifies the name of the action to be dispatched.

  event	    Specifies  the  event  argument  that  will	 be passed to the
	    action routine.

  params    Specifies the action parameters that will be  passed  to  the
	    action routine.

  num_params
	    Specifies the number of elements in params.

Availability
  Release 4 and later.

Description
  An XtActionHookProc registered with XtAppAddActionHook() will be called
  just before any action procedure is invoked by the Translation Manager.
  client_data is whatever data was registered with the action hook proce‐
  dure in the call to XtAppAddActionHook().  action_name is the	 name  of
  the  action  procedure that is about to be invoked.  It is the name the
  action procedure was registered with, and can be  used  in  a	 call  to
  XtCallActionProc().  The w, event, params, and num_params arguments are
  the arguments that will be passed directly to the action procedure.

  Action hooks should not modify any of the data pointed to by the  argu‐
  ments other than the client_data argument.

Usage
  One  use  of	an  XtActionHookProc is to record the arguments passed to
  each action so that user actions are recorded for later playback  using
  XtCallActionProc().  This is one way to implement keyboard macros.
