XmSetProtocolHooks(library call) XmSetProtocolHooks(library call)
NAMEXmSetProtocolHooks — 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);
DESCRIPTIONXmSetProtocolHooks 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 XmSetProto‐
colHooks 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
