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 <X11/Protocols.h>
void XmSetProtocolHooks (shell, property, protocol, prehook, pre_closure,
posthook, post_closure)
Widget shell;
Atom property;
Atom protocol;
XtCallbackProc prehook;
caddr_t pre_closure;
XtCallbackProc posthook;
caddr_t post_closure;
void XmSetWMProtocolHooks (shell, protocol, prehook, pre_closure,
posthook, post_closure)
Widget shell;
Atom protocol;
XtCallbackProc prehook;
caddr_t pre_closure;
XtCallbackProc posthook;
caddr_t 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.
shell Specifies the widget with which the protocol property is
associated
property Specifies the protocol property
protocol Specifies the protocol atom (or an int cast to Atom)
prehook Specifies the procedure to call before calling entries on the
client callback-list
