svn commit: r512810 - in
/xmlgraphics/fop/trunk/src/java/org/apache/fop/layoutmgr/table:
RowPainter.java TableContentLayoutManager.java
Author: vhennebert
Date: Wed Feb 28 07:36:09 2007
New Revision: 512810
URL: http://svn.apache.org/viewvc?view=rev&rev=512810
Log:
Extract RowPainter from TableContentLayoutManager and make it a top-level class.
This is very basic, no change is performed other than adding a field to RowPainter pointing to the formerly enclosing TableContentLayoutManager instance. There will be room for further refactoring later.
Added:
xmlgraphics/fop/trunk/src/java/org/apache/fop/layoutmgr/table/RowPainter.java (with props)
