918 Appendix A: System Routines - Operating System EV_defaultHandler Declaration: void EV_defaultHandler (Event * event) Category(ies): Operating System Description: Defines the default behavior of all events. Your application interacts with the user by responding to events, primarily CM_KEY_PRESS and CM_WPAINT events. But there are many more event types (see section 9.3. Commands) the majority of which your application need not concern itself. Call EV_defaultHandler to deal with any event messages your application does not explicitly handle. Inputs: event - Pointer to event message from the OS. Outputs: None Assumptions: Most events are either acted upon by your application or passed to EV_defaultHandler for default behavior. Some events may need both app processing and default processing. The CM_ACTIVATE event usually requires such handling. When your application receives a CM_ACTIVATE event, it usually calls WinActivate to activate its window, then calls EV_defaultHandler to get automatic menu activation. See section 9.4. Starting and Stopping an Application for details. Side Effects: There can be any number of side effects depending on which event was forwarded to EV_defaultHandler. See section 9.9. Default Event Handler for default actions taken by each event type. Availability: All versions of the TI-89 / TI-92 Plus. TI-89 / TI-92 Plus Differences: None See Also: Not applicable.
