Text Documents 88 Text Documents Text Documents In addition to pure strings, text documents also contain formatting information. These may appear at any point in the text. The structure is further complicated by tables. These include not only single-dimensional strings, but also two-dimensional fields. Most word processing programs now finally provide the option of placing drawing objects, text frames and other objects within a text. These may be outside the flow of text and can be positioned anywhere on the page. This chapter presents the central interfaces and services of text documents. • → The Structure of Text Documents • → Editing Text Documents • → More than Just Text The first section deals with the anatomy of text documents and concentrates on how a OpenOffice.org Basic program can be used to take iterative steps through a OpenOffice.org document. It focuses on paragraphs, paragraph portions and their formatting. The second section focuses on efficiently working with text documents. For this purpose, OpenOffice.org provides several help objects, such as the TextCursor object, which extend beyond those specified in the first section. The third section moves beyond work with texts. It concentrates on tables, text frames, text fields, bookmarks, content directories and more. Information about how to create, open, save and print documents is described in → Working with Documents, because it can be used not only for text documents, but also for other types of documents. Source: http:/ / wiki. services. openoffice. org/ w/ index. php? title=Documentation/ BASIC_ Guide/ Text_ Documents&oldid=96872 Principal Authors: Fpe, Ccornell The Structure of Text Documents A text document can essentially contain four types of information: • The actual text • Templates for formatting characters, paragraphs, and pages • Non-text elements such as tables, graphics and drawing objects • Global settings for the text document This section concentrates on the text and associated formatting options.
The Structure of Text Documents 89 Paragraphs and Paragraph Portions The core of a text document consists of a sequence of paragraphs. These are neither named nor indexed and there is therefore no possible way of directly accessing individual paragraphs. The paragraphs can however be sequentially traversed with the help of the Enumeration object described in → Introduction to the API. This allows the paragraphs to be edited. When working with the Enumeration object, one special scenario should, however, be noted: it not only returns paragraphs, but also tables (strictly speaking, in OpenOffice.org Writer, a table is a special type of paragraph). Before accessing a returned object, you should therefore check whether the returned object supports the com.sun.star.text.Paragraph service for paragraphs or the com.sun.star.text.TextTable service for tables. The following example traverses the contents of a text document in a loop and uses a message in each instance to inform the user whether the object in question is a paragraph or table. Dim Doc As Object Dim Enum As Object Dim TextElement As Object ' Create document object Doc = StarDesktop.CurrentComponent ' Create enumeration object Enum = Doc.Text.createEnumeration ' loop over all text elements While Enum.hasMoreElements TextElement = Enum.nextElement If TextElement.supportsService("com.sun.star.text.TextTable") Then MsgBox "The current block contains a table." End If If TextElement.supportsService("com.sun.star.text.Paragraph") Then MsgBox "The current block contains a paragraph." End If Wend
