block-containers and absolute positioning

[David Neary <Da...@phenix.fr>]

Hi,

I have a feeling this is probably very easy, but I have had 
some trouble doing it. I'm pretty hopeful that one of ye can 
point out the obvious mistake I'm making :)

I'm using fop 0.20.4 on Win32. I would like to lay out a 
letterhead type thing which looks something like this...

+--------+
|        |     Name
|        |     Address 1
|  Logo  |     Address 2
|        |     Phone
|        |     Fax
+--------+


I think that this should be a block container with two blocks 
in it - one containing the external-graphic and one 
containing the rest of the letterhead (I guess I could do it 
with a table too). Then the right-hand block would contain 
one block each for each of the different data items in the letterhead.

So what I ended up with is 

<fo:static-content flow-name="xsl-region-before">
  <fo:block-container font-size="20pt" text-align-last="center">
    <fo:block left="0pt" top="0pt" width="20mm" height="20mm" 
              position="absolute">
 	<fo:external-graphic width="20mm" height="20mm" 
              src="url(http://www.linux.ie/images/tux.gif)"/>
    </fo:block>
    <fo:block left="20mm" top="0pt" width="180mm" 
              height="20mm" position="absolute">
      <fo:block>Tom Jones</fo:block>
      <fo:block>17 Rugby Street</fo:block>
      <fo:block>Cardiff CA12 14GC</fo:block>
    </fo:block>
  </fo:block-container>
</fo:static-content>

The only problem is it doesn't work :) Either I put the two 
blocks in a block, and I get classic block behaviour (logo 
first, then text beneath) or I put them in a block-container, 
and noting gets displayed.

For information, in the page-master, the extent of the before 
is set to 4cm (for testing purposes).

Can anyone help me lay out the header?

Cheers, and thanks for the help,
Dave.

A table would indeed be the more recommended solution.

Specifying position on fo:block has no effect in FOP, it only works on
fo:block-container. You have to use two containers:
  <fo:static-content flow-name="xsl-region-before">
    <fo:block-container left="0pt" top="0pt" width="20mm" height="20mm"
      position="absolute" font-size="20pt" text-align-last="center">
      <fo:external-graphic width="20mm" height="20mm"
        src="url(http://www.linux.ie/images/tux.gif)"/>
    </fo:block-container>
    <fo:block-container left="20mm" top="0pt" width="180mm" height="20mm"
        position="absolute" font-size="20pt" text-align-last="center">
      <fo:block>Tom Jones</fo:block>
      <fo:block>17 Rugby Street</fo:block>
      <fo:block>Cardiff CA12 14GC</fo:block>
    </fo:block-container>
  </fo:static-content>
