NAME
ALLEGRO_USER_EVENT - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro.h> typedef struct ALLEGRO_USER_EVENT ALLEGRO_USER_EVENT;
DESCRIPTION
An event structure that can be emitted by user event sources. These are the public fields: • ALLEGRO_EVENT_SOURCE *source; • intptr_t data1; • intptr_t data2; • intptr_t data3; • intptr_t data4; Like all other event types this structure is a part of the ALLEGRO_EVENT union. To access the fields in an ALLEGRO_EVENT variable ev, you would use: • ev.user.source • ev.user.data1 • ev.user.data2 • ev.user.data3 • ev.user.data4 To create a new user event you would do this: ALLEGRO_EVENT_SOURCE my_event_source; ALLEGRO_EVENT my_event; float some_var; al_init_user_event_source(&my_event_source); my_event.user.type = ALLEGRO_GET_EVENT_TYPE('M','I','N','E'); my_event.user.data1 = 1; my_event.user.data2 = &some_var; al_emit_user_event(&my_event_source, &my_event, NULL); Event type identifiers for user events are assigned by the user. Please see the documentation for ALLEGRO_GET_EVENT_TYPE(3alleg5) for the rules you should follow when assigning identifiers.
