XtAppAddActionHook(3) Library Functions Manual XtAppAddActionHook(3) NAME XtAppAddActionHook, XtRemoveActionHook - register an action hook proce- dure SYNTAX XtActionHookId XtAppAddActionHook(XtAppContext app_context, XtAction- HookProc proc, XtPointer client_data); void XtRemoveActionHook(XtActionHookId id); ARGUMENTS app_context Specifies the application context. proc Specifies the action hook procedure. num_args Specifies the application-specific data to be passed to the action hook. DESCRIPTION XtAppAddActionHook adds the specified procedure to the front of a list maintained in the application context. In the future, when an action routine is about to be invoked for any widget in this application con- text, either through the translation manager or via XtCallActionProc, the action hohok procedures will be called in reverse order of regis- tration jut prior to invoking the action routine. Action hook procedures are removed automatically and the XtActionHookId s destroyed when the application context in which they were added is destroyed. XtRemoveActionHook removes the specified action hook procedure from the list in which it was registered.
