NAME
       gii_expose_event - LibGII expose events

SYNOPSIS
       #include <ggi/events.h>

       typedef struct gii_expose_event {

	   COMMON_DATA;

	   uint32_t  x,y;
	   uint32_t  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 ... */
