From 21ed813d7887b66a8c3cfa0dfceebb162509236e Mon Sep 17 00:00:00 2001 From: tasn Date: Sun, 30 Jan 2011 10:39:52 +0000 Subject: [PATCH] Evas textblock: started using the paragraph layout items a bit more so it's a bit faster now. Fixed a bug in calculating the line number. Paragraph layout items now point to the original paragraphs. git-svn-id: svn+ssh://svn.enlightenment.org/var/svn/e/trunk/evas@56486 7cbeb6ba-43b4-40fd-8cce-4c39aea84d33 --- src/lib/canvas/evas_object_textblock.c | 55 ++++++++++++++++++---------------- 1 file changed, 29 insertions(+), 26 deletions(-) diff --git a/src/lib/canvas/evas_object_textblock.c b/src/lib/canvas/evas_object_textblock.c index 427fc03..0950d97 100644 --- a/src/lib/canvas/evas_object_textblock.c +++ b/src/lib/canvas/evas_object_textblock.c @@ -289,6 +289,7 @@ struct _Evas_Object_Textblock_Paragraph { EINA_INLIST;
