Enable a callout to inform some external module that the display has
|
||||
been updated. This would be useful in a couple for cases.
|
||||
|
||||
- When a serial LCD is used, but a framebuffer is used to access the
|
||||
LCD. In this case, the update callout can be used to refresh the
|
||||
affected region of the display.
|
||||
|
||||
- When VNC is enabled. This is case, this callout is necessary to
|
||||
update the remote frame buffer to match the local framebuffer.
|
||||
|
||||
When this feature is enabled, some external logic must provide this
|
||||
interface:
|
||||
|
||||
void nx_notify_rectangle(FAR NX_PLANEINFOTYPE *pinfo,
|
||||
FAR const struct nxgl_rect_s *rect);
|
||||
|
||||
That is the function that will handle the notification. It
|
||||
receives the rectangular region that was updated in the provided
|
||||
plane.
