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
// Don't forget to add : using namespace com::sun::star::beans; // Don't forget to add : #include <com/sun/star/beans/XPropertySet.hpp> // Don't forget to add "com.sun.star.beans.XPropertySet \" in the makefile // Don't forget to add : using namespace com::sun::star::style; // Don't forget to add : #include <com/sun/star/style/XStyleFamiliesSupplier.hpp> // Don't forget to add "com.sun.star.style.XStyleFamiliesSupplier \" in the makefile // Don't forget to add : using namespace com::sun::star::container;

// Don't forget to add : #include <com/sun/star/style/XStyle.hpp> // Don't forget to add "com.sun.star.style.XStyle \" 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();
// create a text cursor from the cells XText interface
Reference< XTextCursor > xTextCursor = xText->createTextCursor();
// Get the property set of the cell's TextCursor
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.
