LibGII expose events
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 ... */
