OpenOffice.org Code Snippets--Accessing document properties

Recently, I had the task to access document properties before converting a .xls Excel document to a .pdf document. Because , I couldn't find any code-snippets, I'm posting the code here, might be useful to other people.

Code:

Reference< XStyleFamiliesSupplier > xSupplier; Reference< XNameAccess > xFamilies; Reference< XNameContainer > xFamily; // set string for retrieval of OO styles OUString strPageStyleName( OUString::createFromAscii( "PageStyles") ); Reference< XSpreadsheetDocument > xSSDocument( xComponent, UNO_QUERY ); Reference< XTextDocument > xTextDocument( xComponent, UNO_QUERY ); Reference< XDrawPagesSupplier > xDrawPagesSupplier( xComponent, UNO_QUERY ); if ( xSSDocument.is() ) { xSupplier = Reference<XStyleFamiliesSupplier>( xSSDocument,UNO_QUERY ); } else if ( xTextDocument.is() ) { // TextDocuments xSupplier = Reference< XStyleFamiliesSupplier >( xTextDocument,UNO_QUERY ); } else if ( xDrawPagesSupplier.is() ) { // DrawingDocuments Reference< XDrawPages > xDrawPages = xDrawPagesSupplier->getDrawPages(); if ( xDrawPages.is() ) { // get the page count for standard pages int nPageCount = xDrawPages->getCount(); for( int i = 0; i < nPageCount; i++ ) { Reference< XDrawPage > xDrawPage( xDrawPages->getByIndex( i ), UNO_QUERY ); if ( xDrawPage.is() ) { Reference< XPropertySet > xStyleProps( xDrawPage, UNO_QUERY ); if ( xStyleProps.is() ) { Any Width = xStyleProps->getPropertyValue(OUString::createFromAscii("Width")); Any Height = xStyleProps->getPropertyValue(OUString::createFromAscii("Height")); //do changes xStyleProps->setPropertyValue(OUString::createFromAscii("Width"), Width); xStyleProps->setPropertyValue(OUString::createFromAscii("Height"), Height); } } } } } // process doc families if ( xSupplier.is() ) { xFamilies = Reference< XNameAccess >( xSupplier->getStyleFamilies(),UNO_QUERY ); if ( xFamilies.is() ) { xFamily = Reference< XNameContainer >( xFamilies->getByName( strPageStyleName ), UNO_QUERY ); if ( xFamily.is() ) { Sequence<OUString> rNames = xFamily->getElementNames(); // loop trough all page-properties and setup styles where needed for( int i = 0; i < rNames.getLength(); i++ ) { Reference< XStyle > xStyle( xFamily->getByName( rNames[i] ), UNO_QUERY ); if ( ! xStyle.is() ) continue; Reference< XPropertySet > xStyleProps(xStyle, UNO_QUERY); if ( ! xStyleProps.is() ) continue; Any Width = xStyleProps->getPropertyValue(OUString::createFromAscii("Width")); Any Height = xStyleProps->getPropertyValue(OUString::createFromAscii("Height")); // do changes here... xStyleProps->setPropertyValue(OUString::createFromAscii("Width"), Width); xStyleProps->setPropertyValue(OUString::createFromAscii("Height"), Height); } } } }

Now, you'll notice the else if blocks, where I check for different document-types . Three document types are checked: TextDocument, SpreadSheets and DrawingDocument .
