FOP Dynamic Heading Size?

[Devon]

Hi All,
I'm generating a pdf document using FOP .25 from Apache. I've created running dynamic headings (e.g. chapter titles) that change as dictated by the XML source I'm converting to PDF. Now thats fine. My clients wish to include a variable length note as well in this page region. Trouble is I've only been able to do this by statically sizing the region to house this data. If no data (e.g. the note) exists for a given heading - just white space is shown. The clients hate it and apparently this is a show-stopping issue. A mustfix.

Is there a way to have the fo-region-before shrink / grow dynamically based on the data display within that region?

I know I have done this in Java, but is there a way to do it in C++?

Type B and C inherit from type A.

In a function, I want to check an instance of A (which can also be B or C), to see what it is, and move on... something like:

A something;
if( A.typeof(B) )
{
B somethingB = static_cast<B>(something);
// Do things with the B members
}
else if ( A.typeof(C) )
{
C somethingC = static_cast<C>(something);
// Do things with the C members
}
else
{
// Do things with the A members
}

I know I can accomplish something similar with virtual functions (polymorphism), but can the above be done in any way?

Just curious.

You do realise that this is a JavaScript group, don't you?

Try asking in comp.lang.c++

AFAIK, yes.

Go ask in a C group.

The size of a static-content region can't be dynamic, but you can calc the size based on the size of your note. Ex:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">

<xsl:template match="/">
<fo:root>
<fo:layout-master-set>

<xsl:variable name="size" select="string-length(/xml/note/text) div 50"/>

<fo:simple-page-master master-name="report_page_master" page-height="11in" page-width="8.5in"> <fo:region-body region-name="xsl-region-body" margin=".5in" margin-top="{$size}in"/>

....

This counts the number of chars making up the note node to calc the size. You'll probaly want to figure out your own magic number instead of 50, but you'll want to use that variable in the margin-top of region-body and the extent of region-before.

ARGHHHHH!!!!!!!

I feel like a stooge. I actively follow two news groups... alt.lang.javascript, and alt.lang.c++. I accadently posted to the wrong group.

The reason I feel so bad, is because I always get frustrated with incorrect postings to the different groups, weather it be java questions in the javascript group, or MFC questions in the C++ group.

How about a C++ question in the javascript group?

Blah,
