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 fro= m `redisplay_preserve_echo_area'. I did understand that every line is filled with glyphs in `display_line' us= ing an interator structure. However, I do not understand the mechanism from `redisplay_ineternal' (I ha= ve the impression that it's this function that creates the desired_matrix o= f glyphs) and refresh the display. Thanks in advance. ____________________________________________________Avec Voila, r=C3=A9alis= ez en toute simplicit=C3=A9 votre videoblog ! http://video.voila.fr/mktg/?o= p=3Dvideoblog
