E.g.
* They will have been arguing whole day.
* I shall have been reading two hours.
* The class teachers will have been preparing progress charts of the students.

"The future perfect continuous tense shows that the action will be going on before it will be finished at a certain future time."
As I mention in a comment to another one of your blog posts, 'perfect' tends to be used to focus attention on the completion or result of an action; in contrast, 'continuous' tends to emphasize the activity in progress.
So when we use past, present or future perfect continuous, we want to emphasize the result of an activity. For instance:
I've been working all day. (suggesting I've worked A LOT; I'm tired now and don't want to work anymore)
They will have been arguing the whole day. (emphasizing the argument continued - and may continue further into the future - for a LONG time)
As you see with cleft sentences and passive forms (for instance), we choose to use these grammatical structures to help focus our reader/listener and give emphasis to our main idea or message.
Thank you Marcus for your explanations.
Good luck for all.
