man gii_expose_event (Fonctions bibliothèques) - gii_expose_event : LibGII expose events

NAME

gii_expose_event : LibGII expose events

SYNOPSIS

#include <ggi/events.h>

typedef struct gii_expose_event {

COMMON_DATA;

uint32 x,y; uint32 h,w;

} gii_expose_event;

DESCRIPTION

If an application loses the focus and is not physically displayed (e.g. console switching, iconifying), it may be stopped. Some targets may implement a backbuffer and allow continuing, though.

After reactivation, the application will receive a redraw event, evExpose.

GENERATED EVENTS

The gii_expose_event is used for the evExpose event.

STRUCTURE MEMBERS

The fields describe the region which needs to be redrawn.

EXAMPLES

evExpose handling skeleton:

ggi_visual_t vis;
ggi_event ev;

/* ... wait and get the event... */

if (ev.any.type == evExpose) { /* We might not be able to render partially ... */ render_screen(vis); /* but flush only the region needed */ ggiFlushRegion(vis, ev.expose.x, ev.expose.y, ev.expose.w, ev.expose.h); }

/* ... etc ... */
