GdkEventExpose

Generated when all or part of a window becomes visible and needs to be redrawn. GdkEventType type; the type of the event (GDK_EXPOSE or GDK_DAMAGE). GdkWindow *window; the window which received the event. gint8 send_event; TRUE if the event was sent explicitly (e.g. using XSendEvent). GdkRectangle area; bounding box of region. cairo_region_t *region; the region that needs to be redrawn. gint count; the number of contiguous GDK_EXPOSE events following this one. The only use for this is "exposure compression", i.e. handling all contiguous GDK_EXPOSE events in one go, though GDK performs some exposure compression so this is not normally needed.
