"display-invalidate" : Run First "display-mark" : Run First "display-primary-create" : Run First "display-primary-destroy" : Run First
A class that handles the rendering of the remote display and inform of its updates.
The creation of the main graphic buffer is signaled with "display-primary-create".
The update of regions is notified by "display-invalidate" signals.
typedef struct _SpiceDisplayChannel SpiceDisplayChannel;
The SpiceDisplayChannel struct is opaque and should not be accessed directly.
typedef struct { SpiceChannelClass parent_class; /* signals */ void (*display_primary_create)(SpiceChannel *channel, gint format, gint width, gint height, gint stride, gint shmid, gpointer data); void (*display_primary_destroy)(SpiceChannel *channel); void (*display_invalidate)(SpiceChannel *channel, gint x, gint y, gint w, gint h); void (*display_mark)(SpiceChannel *channel, gboolean mark); } SpiceDisplayChannelClass;
