NAME

gii_expose_event - LibGII expose events
 

SYNOPSIS

#include <ggi/events.h>

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

typedef struct gii_expose_event {

        COMMON_DATA;

        uint32  x,y;
        uint32  h,w;

} gii_expose_event;

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 ... */
