OpenOffice::OODoc howto set size for textboxes

[codeacrobat]

Hello monks, I am doing some OpenOffice automation. For ages I am trying to find the right permutation of style definitions that give me an Impress document with one textbox containing "hello world" with font size 36. Can anyone point me to the right definition? Also I would be happy about some links to real life examples for OpenOffice::OODoc. This is what I tried so far. I figured out that somehow you need a style for the textbox and a separate style for the text itself.

use OpenOffice::OODoc;

my $document = ooDocument(
    file   => 'outputfile.odp',
    create => 'presentation'
);

$document->createStyle(
    "TB",
    family     => "paragraph",
    parent     => "objectwithshadow",
    properties => {
        'style:vertical-pos'     => 'from-top',
        'style:horizontal-pos'   => 'from-left',
        'style:vertical-rel'     => 'page',
        'style:horizontal-rel'   => 'page',
        'style:font-size'        => '36pt',
        'style:font-weight'      => 'bold',

    }
);

$document->createStyle
                (
                "Colour",
                family  => 'paragraph',
                parent  => 'Standard',
                properties =>
                        {
                        'fo:margin-left'        => '2cm',
                        'fo:margin-right'       => '1.5cm',
                        'fo:text-align'         => 'justify',
                        'fo:background-color'   => '#ff00ff'
                        'fo:font-size'        => '36pt',
                        }
                );

$para = $document->createParagraph( "hello world", "Colour" );

$slide = $document->getDrawPage(0);

$document->createTextBox(
    attachment => $slide,
    size       => '10cm, 10cm',
    position   => '4cm,4cm',
    content    => $para,
    style      => 'TB',
);

$document->save;

*Solved*
OpenOffice::OODoc::Styles says the following on createStyle:

We could provide this new style with additional properties related to the text content of the paragraph. But, in a paragraph style definition, the "text" properties are not stored in the same logical area than the "paragraph" properties, and we can't set both in the same instruction. Fortunately, we can enrich any existing style at any time through the updateStyle() method

It has to be splitted into two statements. I just tested something similar successfully.

$document->createStyle
                (
                "Colour",
                family  => 'paragraph',
                parent  => 'Standard'
);
$document->updateStyle(
                "Colour",
                family     => 'paragraph',
                parent     => 'Standard',
                properties =>
                        {
                        'fo:margin-left'        => '2cm',
                        'fo:margin-right'       => '1.5cm',
                        'fo:text-align'         => 'justify',
                        'fo:background-color'   => '#ff00ff'
                        'fo:font-size'        => '36pt',
                        }
                );
