From 504454e82487c7a50db87edfb67461701a4e4b65 Mon Sep 17 00:00:00 2001 From: Gerd Moellmann Date: Sat, 23 Dec 2000 15:32:07 +0000 Subject: [PATCH] (syms_of_xdisp): Doc fix. (redisplay_window): Remove label restore_buffers; use finish_scroll_bars instead to make sure that scroll bars are redeemed. If we don't do this, flickering can result from scroll bars being destroyed and recreated. --- src/xdisp.c | 34 ++++++++++++++++------------------ 1 file changed, 16 insertions(+), 18 deletions(-) diff --git a/src/xdisp.c b/src/xdisp.c index 295488e0c9..8253b6c878 100644 --- a/src/xdisp.c +++ b/src/xdisp.c @@ -8305,7 +8305,7 @@ redisplay_internal (preserve_echo_area) /* Mark all the scroll bars to be removed; we'll redeem the ones we want when we redisplay their windows. */ if (condemn_scroll_bars_hook) - (*condemn_scroll_bars_hook) (f); + condemn_scroll_bars_hook (f); if (FRAME_VISIBLE_P (f) && !FRAME_OBSCURED_P (f)) redisplay_windows (FRAME_ROOT_WINDOW (f)); @@ -8313,7 +8313,7 @@ redisplay_internal (preserve_echo_area) /* Any scroll bars which redisplay_windows should have nuked should now go away. */ if (judge_scroll_bars_hook) - (*judge_scroll_bars_hook) (f); + judge_scroll_bars_hook (f); /* If fonts changed, display again. */ if (fonts_changed_p) @@ -9599,7 +9599,7 @@ redisplay_window (window, just_this_one_p) { w->force_start = Qt; clear_glyph_matrix (w->desired_matrix); - goto restore_buffers; + goto finish_scroll_bars; } if (w->cursor.vpos < 0 && !w->frozen_window_start_p) @@ -9632,7 +9632,7 @@ redisplay_window (window, just_this_one_p) { clear_glyph_matrix (w->desired_matrix); if (!try_window (window, startp)) - goto restore_buffers; + goto finish_scroll_bars; } } @@ -9702,7 +9702,7 @@ redisplay_window (window, just_this_one_p) #endif if (fonts_changed_p) - goto restore_buffers; + goto finish_scroll_bars; if (tem > 0) goto done; @@ -9737,7 +9737,7 @@ redisplay_window (window, just_this_one_p) } if (fonts_changed_p) - goto restore_buffers; + goto finish_scroll_bars; if (w->cursor.vpos >= 0) { @@ -9785,7 +9785,7 @@ redisplay_window (window, just_this_one_p) if (rc > 0) goto done; else if (rc < 0) - goto restore_buffers; + goto finish_scroll_bars; } /* Finally, just choose place to start which centers point */ @@ -9846,7 +9846,7 @@ redisplay_window (window, just_this_one_p) have to start a new redisplay since we need to re-adjust glyph matrices. */ if (fonts_changed_p) - goto restore_buffers; + goto finish_scroll_bars; /* If cursor did not appear assume that the middle of the window is in the first line of the window.
