Subject: bug#20180: Missing documentation about redisplay.
Date: Mon, 23 Mar 2015 16:08:50 +0000 [thread overview]
Message-ID: <20150323160850.GA23576@acm.fritz.box> (raw)
Hello, Emacs.
The elisp manual doesn't contain adequate documentation about
(re)display.
The topics not covered include
1. What triggers redisplay.
2. What portions of the frame/all frames get redisplayed when a
redisplay occurs, and how does this relate to the answer to 1..
There is a partial answer to 1. on the page "Forcing Redisplay" which
states that "Emacs normally tries to redisplay the screen whenever it
waits for input.", but this is clearly incomplete - redisplay also
happens in the absence of input (e.g. by context fontification).
One clearly needs an answer to 2. if one ever wants to cause the
redisplay of a particular part of a window or frame.
