From: Abdelrazak Younes Date: Sun, 19 Oct 2008 07:03:44 +0000 (+0000) Subject: Paragraph: X-Git-Tag: 1.6.10~2989 X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=6a8219c190315a63426e6798290cc3a04dbc0f09;p=lyx.git Paragraph: - constify some parameters - getFontSettings(): - getFirstFontSettings(): return a const ref instead of a copy. This brings a consistent 4% improvement in LateX generation. Might speedup rtl handling too. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@26957 a592a061-630c-0410-9148-cb99ea01b6c8 --- diff --git a/src/CutAndPaste.cpp b/src/CutAndPaste.cpp index 5f1410726b..8a13b87fdf 100644 --- a/src/CutAndPaste.cpp +++ b/src/CutAndPaste.cpp @@ -915,7 +915,7 @@ void replaceSelectionWithString(Cursor & cur, docstring const & str, bool backwa DocIterator selbeg = cur.selectionBegin();
