Styles

A style contains all formatting properties for a specific object. All styles of the same type are contained in a collection named a style family. Each style family has a specific name to identify it in the collection. In Apache OpenOffice API Calc, there are two style families named CellStyles and PageStyles. A cell style can be applied to a cell, a cell range, or all cells of the spreadsheet. A page style can be applied to a spreadsheet itself.

StyleFamilies

The collection of style families is available from the spreadsheet document with the com.sun.star.style.XStyleFamiliesSupplier's method getStyleFamilies(). The general handling of styles is described in this section, therefore this chapter focuses on the spreadsheet specific style properties.

Cell Styles

Cell styles are predefined packages of format settings that are applied in a single step.

CellStyle

A cell style is represented by the service com.sun.star.sheet.TableCellStyle. If a formatting property is applied directly to a cell, it covers the property of the applied cell style. This service does not support the property CellStyle. The name of the style is set with the interface com.sun.star.container.XNamed.

The following example creates a new cell style with gray background. The xDocument is the com.sun.star.sheet.XSpreadsheetDocument interface of a spreadsheet document.

  // get the cell style container
  com.sun.star.style.XStyleFamiliesSupplier xFamiliesSupplier =
      (com.sun.star.style.XStyleFamiliesSupplier) UnoRuntime.queryInterface(
          com.sun.star.style.XStyleFamiliesSupplier.class, xDocument);
  com.sun.star.container.XNameAccess xFamiliesNA = xFamiliesSupplier.getStyleFamilies();
  Object aCellStylesObj = xFamiliesNA.getByName("CellStyles");
  com.sun.star.container.XNameContainer xCellStylesNA = (com.sun.star.container.XNameContainer)
      UnoRuntime.queryInterface(com.sun.star.container.XNameContainer.class, aCellStylesObj);
 
  // create a new cell style
  com.sun.star.lang.XMultiServiceFactory xServiceManager = (com.sun.star.lang.XMultiServiceFactory)
      UnoRuntime.queryInterface(com.sun.star.lang.XMultiServiceFactory.class, xDocument);
  Object aCellStyle = xServiceManager.createInstance("com.sun.star.style.CellStyle");
  xCellStylesNA.insertByName("MyNewCellStyle", aCellStyle);
 
  // modify properties of the new style
  com.sun.star.beans.XPropertySet xPropSet = (com.sun.star.beans.XPropertySet)
      UnoRuntime.queryInterface(com.sun.star.beans.XPropertySet.class, aCellStyle);
  xPropSet.setPropertyValue("CellBackColor", new Integer(0x888888));
  xPropSet.setPropertyValue("IsCellBackgroundTransparent", new Boolean(false));

Page Styles

A page style is represented by the service com.sun.star.sheet.TablePageStyle. It contains the service com.sun.star.style.PageStyle and additional spreadsheet specific page properties.

TablePageStyle

The properties LeftPageFooterContent, LeftPageHeaderContent, RightPageFooterContent and RightPageHeaderContent return the interface com.sun.star.sheet.XHeaderFooterContent for the headers and footers for the left and right pages. Headers and footers are represented by the service com.sun.star.sheet.HeaderFooterContent. Each header or footer object contains three text objects for the left, middle and right portion of a header or footer. The methods getLeftText(), getCenterText() and getRightText() return the interface com.sun.star.text.XText of these text portions.

Documentation note.png After the text of a header or footer is changed, it is reinserted into the property set of the page style.
