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 For a complete definition of VendorShell and its associated resources, see VendorShell(3X).

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. SEE ALSO
