Translating Java Code in cpp

We start with an example found in OOoForum under the title : Setting the page properties/margins directly from java

Here is the Java code : [java] //Listing 33 A Java Code Example // Java // create new writer document and get text, then manipulate text

XComponent xWriterComponent = newDocComponent("swriter"); 
XTextDocument xTextDocument = (XTextDocument)UnoRuntime.queryInterface(XTextDocument.class,xWriterComponent); 
// Access the text document's multi service factory, which we will need for most of the 
// following examples 
mxDocFactory = (XMultiServiceFactory) UnoRuntime.queryInterface

(XMultiServiceFactory.class,xTextDocument);

XText xText = xTextDocument.getText(); 
// create a text cursor from the cells XText interface 
XTextCursor xTextCursor = xText.createTextCursor(); 
// Get the property set of the cell's TextCursor 
XPropertySet xTextCursorProps = (XPropertySet)UnoRuntime.queryInterface

(XPropertySet.class,xTextCursor);

// Page Style name 
String pageStyleName= xTextCursorProps.getPropertyValue("PageStyleName").toString(); 
// Get the StyleFamiliesSupplier interface of the document 
XStyleFamiliesSupplier xSupplier = (XStyleFamiliesSupplier) UnoRuntime.queryInterface

(XStyleFamiliesSupplier.class,xTextDocument);

// Use the StyleFamiliesSupplier interface to get the XNameAccess interface of the 
// actual style families 
XNameAccess xFamilies = (XNameAccess)UnoRuntime.queryInterface(XNameAccess.class,

xSupplier.getStyleFamilies());

// Access the 'PageStyles' Family 
XNameContainer xFamily = (XNameContainer) UnoRuntime.queryInterface

(XNameContainer.class,xFamilies.getByName("PageStyles"));

// Insert the newly created style into the PageStyles family 
XStyle xStyle= (XStyle) UnoRuntime.queryInterface(XStyle.class,xFamily.getByName

(pageStyleName));

// Get the property set of the TextCursor 
XPropertySet xStyleProps = (XPropertySet)UnoRuntime.queryInterface

(XPropertySet.class,xStyle);

xStyleProps.setPropertyValue("LeftMargin",new Short((short)1200)); 
xStyleProps.setPropertyValue("RightMargin",new Short((short)1200)); 
xStyleProps.setPropertyValue("BottomMargin",new Short((short)1200)); 

The C++ translation gives : [cpp] //Listing 34 The corresponding C++ Translation // C++ // create new writer document and get text, then manipulate text

// Don't forget to add : using namespace com::sun::star::text; // Don't forget to add : #include <com/sun/star/text/XTextDocument.hpp> // Don't forget to add "com.sun.star.text.XTextDocument \" in the makefile

// the first line cannot be translated : already done in our main() // XComponent xWriterComponent = newDocComponent("swriter");

Reference < XTextDocument > xTextDocument (xWriterComponent,UNO_QUERY);

// Access the text document's multi service factory, which we will need for most of the
// following examples

Reference< XMultiServiceFactory > mxDocFactory(xTextDocument,UNO_QUERY); Reference< XText > xText = xTextDocument->getText();

Reference< XPropertySet > xTextCursorProps(xTextCursor,UNO_QUERY);

// Page Style name 
//*** I add a intermediate variable because of Any type returned by getPropertyValue 

Any pageStyleName2 = xTextCursorProps->getPropertyValue (OUString::createFromAscii("PageStyleName")); OUString pageStyleName; pageStyleName2 >>= pageStyleName ;

 // Get the StyleFamiliesSupplier interface of the document

Reference< XStyleFamiliesSupplier > xSupplier(xTextDocument,UNO_QUERY);

// Use the StyleFamiliesSupplier interface to get the XNameAccess interface of the
// actual style families

Reference< XNameAccess > xFamilies(xSupplier->getStyleFamilies(),UNO_QUERY);

// Access the 'PageStyles' Family 

Reference< XNameContainer > xFamily(xFamilies->getByName (OUString::createFromAscii("PageStyles")),UNO_QUERY); // Insert the newly created style into the PageStyles family Reference< XStyle > xStyle(xFamily->getByName(pageStyleName),UNO_QUERY);

// Get the property set of the TextCursor 

Reference< XPropertySet > xStyleProps(xStyle,UNO_QUERY); Any lm, rm, bm; lm<<=(short)1200; rm<<=(short)1200; bm<<=(short)1200; xStyleProps->setPropertyValue(OUString::createFromAscii("LeftMargin"),lm); xStyleProps->setPropertyValue(OUString::createFromAscii("RightMargin"),rm); xStyleProps->setPropertyValue(OUString::createFromAscii("BottomMargin"),bm); My skills on Any type is not complete enough, then I don't find a straight forwarder way in using Any than using intermediate variables. See the last three lines for instance.
