From: Karen Lease Date: Wed, 2 May 2001 21:00:49 +0000 (+0000) Subject: Stop tables from breaking too early, but make sure that all cells are X-Git-Tag: PRE_CODEFORMATTING~145 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=16b22d92e4700ed10c012b023c17ec9792e3f0fa;p=xmlgraphics-fop.git Stop tables from breaking too early, but make sure that all cells are composed with the same maxHeight and that absolute Height is set correctly. In TableRow.java, remove old commented out stuff and put back space-before (for now) and fix a potential bug involving space-before. git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@194232 13f79535-47bb-0310-9956-ffa450edef68 --- diff --git a/src/org/apache/fop/fo/flow/TableCell.java b/src/org/apache/fop/fo/flow/TableCell.java index a5c17aba8..709ef892f 100644 --- a/src/org/apache/fop/fo/flow/TableCell.java +++ b/src/org/apache/fop/fo/flow/TableCell.java @@ -175,7 +175,8 @@ public class TableCell extends FObj { fo.setIsInTableCell(); fo.forceWidth(width); // ??? - // Overflows may cause a row to be re-layedout, need to pass already processed content. + // Overflows may cause a row to be re-layedout, + // need to pass already processed content. this.marker = i; Status status; @@ -186,7 +187,7 @@ public class TableCell extends FObj { } else { // hani Elabed 11/21/2000 area.addChild(cellArea); - area.setAbsoluteHeight(cellArea.getAbsoluteHeight()); + // area.setAbsoluteHeight(cellArea.getAbsoluteHeight()); return new Status(Status.AREA_FULL_SOME); } } @@ -205,8 +206,8 @@ public class TableCell extends FObj { // reset absoluteHeight to beginning of row // area.setHeight(cellArea.getHeight() + spaceBefore + spaceAfter); // I don't think we should do this here (KL) !!! - area.setHeight(cellArea.getHeight()); - area.setAbsoluteHeight(originalAbsoluteHeight); + // area.setHeight(cellArea.getHeight()); + //area.setAbsoluteHeight(originalAbsoluteHeight); return new Status(Status.OK); } diff --git a/src/org/apache/fop/fo/flow/TableRow.java b/src/org/apache/fop/fo/flow/TableRow.java index cf36b0e06..da12002e0 100644 --- a/src/org/apache/fop/fo/flow/TableRow.java +++ b/src/org/apache/fop/fo/flow/TableRow.java @@ -1,52 +1,7 @@ /*-- $Id$ -- - - ============================================================================ - The Apache Software License, Version 1.1 - ============================================================================ - - Copyright (C) 1999 The Apache Software Foundation.
