From b922cfd3b351683fa452eeec4830258d72d47ab8 Mon Sep 17 00:00:00 2001 From: Richard Heck Date: Fri, 21 Mar 2008 17:45:14 +0000 Subject: [PATCH] Another attempt at 2178. This is a "minimal" patch designed to fix the bug with the minimum amount of new code. A better fix, suggested by Andre, would merge InsetTableCell and CellData into one class, in which case InsetTableCell::cell_data_ can be removed. A definite plus. I'll do that later if this works. But let's get it right first. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@23879 a592a061-630c-0410-9148-cb99ea01b6c8 --- src/Paragraph.cpp | 29 ++----------- src/insets/Inset.cpp | 1 + src/insets/InsetCode.h | 2 + src/insets/InsetTabular.cpp | 82 ++++++++++++++++++++++++++++++++----- src/insets/InsetTabular.h | 52 +++++++++++++++++++---- src/insets/InsetText.cpp | 16 -------- src/insets/InsetText.h | 4 -- 7 files changed, 120 insertions(+), 66 deletions(-) diff --git a/src/Paragraph.cpp b/src/Paragraph.cpp index 18b73346b9..6aeab1aa7d 100644 --- a/src/Paragraph.cpp +++ b/src/Paragraph.cpp @@ -48,8 +48,6 @@ #include "insets/InsetBibitem.h" #include "insets/InsetLabel.h" -// needed only for inTableCell() -#include "insets/InsetText.h" #include "support/convert.h" #include "support/debug.h" @@ -1621,7 +1619,6 @@ bool Paragraph::forceEmptyLayout() const Inset const * const inset = inInset();
