NAME

XmSetProtocolHooks --- A VendorShell function that allows preactions and postactions to be executed when a protocol message is received from MWM  

SYNOPSIS

#include <Xm/Xm.h>
#include <Xm/Protocols.h>
void XmSetProtocolHooks(
Widget shell,
Atom property,
Atom protocol,
XtCallbackProc prehook,
XtPointer pre_closure,
XtCallbackProc posthook,
XtPointer post_closure);
 

DESCRIPTION

XmSetProtocolHooks is used by shells that want to have preactions and postactions 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.
