From e61124cd850ad6e0fc511dc995031db77b3535cd Mon Sep 17 00:00:00 2001 From: YAMAMOTO Mitsuharu Date: Wed, 25 May 2011 12:06:05 +0900 Subject: [PATCH] Take account of periodic fringe bitmap's dependency on y-position in redrawing. * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p. * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row for fringe update if it has periodic bitmap. (row_equal_p): Also compare left_fringe_offset, right_fringe_offset, and fringe_bitmap_periodic_p. * fringe.c (get_fringe_bitmap_data): New function. (draw_fringe_bitmap_1, update_window_fringes): Use it. (update_window_fringes): Record periodicity of fringe bitmap in glyph row. Mark glyph row for fringe update if periodicity changed. * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row for fringe update unless it has periodic bitmap. --- src/ChangeLog | 17 +++++++++++++++++ src/dispextern.h | 4 ++++ src/dispnew.c | 13 ++++++------- src/fringe.c | 39 +++++++++++++++++++++++++-------------- src/xdisp.c | 6 ++++-- 5 files changed, 56 insertions(+), 23 deletions(-) diff --git a/src/ChangeLog b/src/ChangeLog index cdc8ed8999c..3f53eabb5d1 100644 --- a/src/ChangeLog +++ b/src/ChangeLog @@ -1,3 +1,20 @@ +2011-05-25 YAMAMOTO Mitsuharu + + * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p. + + * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row + for fringe update if it has periodic bitmap. + (row_equal_p): Also compare left_fringe_offset, right_fringe_offset, + and fringe_bitmap_periodic_p. + + * fringe.c (get_fringe_bitmap_data): New function. + (draw_fringe_bitmap_1, update_window_fringes): Use it. + (update_window_fringes): Record periodicity of fringe bitmap in glyph + row.
