NAME

       XmSetProtocolHooks - A VendorShell function that allows pre and post actions to be executed when a protocol message is received from MWM

SYNOPSIS

       #include <Xm/Xm.h> #include <Xm/Protocols.h>

       void XmSetProtocolHooks (shell, property, protocol, prehook, pre_closure, posthook, post_closure)
	       Widget shell;
	       Atom property;
	       Atom protocol;
	       XtCallbackProc prehook;
	       XtPointer pre_closure;
	       XtCallbackProc posthook;
	       XtPointer post_closure;

       void XmSetWMProtocolHooks (shell, protocol, prehook, pre_closure, posthook, post_closure)
	       Widget shell;
	       Atom protocol;
	       XtCallbackProc prehook;
	       XtPointer pre_closure;
	       XtCallbackProc posthook;
	       XtPointer post_closure;

DESCRIPTION

       XmSetProtocolHooks  is  used  by shells that want to have pre and post actions executed when a protocol message is received from MWM. Since
       there is no guaranteed ordering in execution of event handlers or callback lists, this allows the shell to control the flow  while  leaving
       the protocol manager structures opaque.

       XmSetWMProtocolHooks is a convenience interface.  It calls XmSetProtocolHooks with the property value set to the atom returned by interning
       WM_PROTOCOLS.  Specifies the widget with which the protocol property is associated Specifies the protocol property Specifies  the  protocol
       atom  (or an int cast to Atom) Specifies the procedure to call before calling entries on the client callback-list Specifies the client data
       to be passed to the prehook when it is invoked Specifies the procedure to call after calling entries on the client callback-list  Specifies
       the client data to be passed to the posthook when it is invoked

NAME

       XtAddCallback, XtAddCallbacks, XtRemoveCallback, XtRemoveCallbacks, XtRemoveAllCallbacks - add and remove callback procedures

SYNTAX

       void XtAddCallback(w, callback_name, callback, client_data)
	     Widget w;
	     String callback_name;
	     XtCallbackProc callback;
	     XtPointer client_data;

       void XtAddCallbacks(w, callback_name, callbacks)
	     Widget w;
	     String callback_name;
	     XtCallbackList callbacks;

       void XtRemoveCallback(w, callback_name, callback, client_data)
	     Widget w;
	     String callback_name;
	     XtCallbackProc callback;
	     XtPointer client_data;

       void XtRemoveCallbacks(w, callback_name, callbacks)
	     Widget w;
	     String callback_name;
	     XtCallbackList callbacks;

       void XtRemoveAllCallbacks(w, callback_name)
	     Widget w;
	     String callback_name;

ARGUMENTS

       callback  Specifies the callback procedure.

       callbacks Specifies the null-terminated list of callback procedures and corresponding client data.

       callback_name
		 Specifies the callback list to which the procedure is to be appended or deleted.  or the client data to match on the registered
		 callback procedures

       client_data
		 Specifies the argument that is to be passed to the specified procedure when it is invoked by XtCallbacks or NULL,.

       w	 Specifies the widget.

DESCRIPTION

       The XtAddCallback function adds the specified callback procedure to the specified widget's callback list.

       The XtAddCallbacks add the specified list of callbacks to the specified widget's callback list.

       The XtRemoveCallback function removes a callback only if both the procedure and the client data match.

       The XtRemoveCallbacks function removes the specified callback procedures from the specified widget's callback list.

       The XtRemoveAllCallbacks function removes all the callback procedures from the specified widget's callback list.
