Subject: help about the display iterator.

Message-ID: <3745216.88811232043706461.JavaMail.www@wwinf4607> (raw)

Hello,

Please, can somebody make me a brief resume ( in a few words ) about how the `display iterator' works?

I saw that the low-level functions of the display of emacs there are called from `redisplay internal', which is called mainly from `redisplay' and from `redisplay_preserve_echo_area'.

I did understand that every line is filled with glyphs in `display_line' using an interator structure.

However, I do not understand the mechanism from `redisplay_ineternal' (I have the impression that it's this function that creates the desired_matrix of glyphs) and refresh the display.

Thanks in advance.
