Overview of Central Interfaces com.sun.star.container.XEnumeration and XenumerationAccess Interfaces The basic object must provide the XEnumerationAccess interface, which contains only a createEnumeration method. This returns an auxiliary object, which in turn provides the XEnumeration interface with the hasMoreElements and nextElement methods. Through these, you then have access to the subordinate objects. The following example steps through all the paragraphs of a text: Dim ParagraphEnumeration As Object Dim Paragraph As Object ParagraphEnumeration = Textdoc.Text.createEnumeration While ParagraphEnumeration.hasMoreElements() Paragraph = ParagraphEnumeration.nextElement() Wend The example first creates a ParagraphEnumeration auxiliary object. This gradually returns the individual paragraphs of the text in a loop. The loop is terminated as soon as the hasMoreElements method returns the False value, signaling that the end of the text has been reached. Chapter 4 · Introduction to the API 57
5 C H A P T E R 5 5 Working with Documents The OpenOffice.org API has been structured so that as many of its parts as possible can be used universally for different tasks. This includes the interfaces and services for creating, opening, saving, converting, and printing documents and for template administration. Since these function areas are available in all types of documents, they are explained first in this chapter. The StarDesktop Styles and Templates The current document In previous versions of the Basic Programming Guide these instructions were used to obtain the current document : Dim Doc As Object Doc = StarDesktop.CurrentComponent This correct code has a drawback : it does not work if the macro is started from the IDE because it then refers to the IDE, not the document. This code works only if the macro is started from the document itself! You should instead use Basic object ThisComponent. It returns the document object on which the macro is run. If you start the macro from the IDE, ThisComponent will still find and return your document. Dim Doc As Object Doc = ThisComponent ' recommended coding for Basic The StarDesktop When working with documents, two services are used most frequently: The com.sun.star.frame.Desktop service, which is similar to the core service of OpenOffice.org. It provides the functions for the frame object of OpenOffice.org, under which all document windows are classified. Documents can also be created, opened and imported using this service. The basic functionality for the individual document objects is provided by the com.sun.star.document.OfficeDocument service. This provides the methods for saving, exporting and printing documents. The com.sun.star.frame.Desktop service is created automatically when OpenOffice.org is started. This service can be addressed in OpenOffice.org Basic using the global name StarDesktop. The most important interface of the StarDesktop is com.sun.star.frame.XComponentLoader. This basically 59
