Editing Text Documents Cursor.goLeft(10, False) Cursor.goRight(3, False) A TextCursor can highlight a complete area. This can be compared with highlighting a point in the text using the mouse. The False parameter in the previous function call specifies whether the area passed over with the cursor movement is highlighted. For example, the TextCursor in the following example Cursor.goRight(10, False) Cursor.goLeft(3, True) first moves ten characters to the right without highlighting, and then moves back three characters and highlights this. The area highlighted by the TextCursor therefore begins after the seventh character in the text and ends after the tenth character. Here are the central methods that the com.sun.star.text.TextCursor service provides for navigation: goLeft (Count, Expand) jumps Count characters to the left. goRight (Count, Expand) jumps Count characters to the right. gotoStart (Expand) jumps to the start of the text document. gotoEnd (Expand) jumps to the end of the text document. gotoRange (TextRange, Expand) jumps to the specified TextRange-Object. gotoStartOfWord (Expand) jumps to the start of the current word. gotoEndOfWord (Expand) jumps to the end of the current word. gotoNextWord (Expand) jumps to the start of the next word. gotoPreviousWord (Expand) jumps to the start of the previous word. isStartOfWord () returns True if the TextCursor is at the start of a word. isEndOfWord () returns True if the TextCursor is at the end of a word. gotoStartOfSentence (Expand) jumps to the start of the current sentence. gotoEndOfSentence (Expand) jumps to the end of the current sentence. gotoNextSentence (Expand) jumps to the start of the next sentence. gotoPreviousSentence (Expand) jumps to the start of the previous sentence. isStartOfSentence () returns True if the TextCursor is at the start of a sentence. 76 OpenOffice.org 3.2 BASIC Guide · March 2010
isEndOfSentence () returns True if the TextCursor is at the end of a sentence. gotoStartOfParagraph (Expand) jumps to the start of the current paragraph. gotoEndOfParagraph (Expand) jumps to the end of the current paragraph. gotoNextParagraph (Expand) jumps to the start of the next paragraph. gotoPreviousParagraph (Expand) jumps to the start of the previous paragraph. isStartOfParagraph () returns True if the TextCursor is at the start of a paragraph. isEndOfParagraph () returns True if the TextCursor is at the end of a paragraph. Editing Text Documents The text is divided into sentences on the basis of sentence symbols. Periods are, for example, interpreted as symbols indicating the end of sentences. (In English, at least, they must be followed by a space, tab, or return for this to work.) The Expand parameter is a Boolean value which specifies whether the area passed over during navigation is to be highlighted. All navigation methods furthermore return a Boolean parameter which specifies whether the navigation was successful or whether the action was terminated for lack of text. The following is a list of several methods for editing highlighted areas using a TextCursor and which also support the com.sun.star.text.TextCursor service: collapseToStart () resets the highlighting and positions the TextCursor at the start of the previously highlighted area. collapseToEnd () resets the highlighting and positions the TextCursor at the end of the previously highlighted area. isCollapsed () returns True if the TextCursor does not cover any highlighting at present. Formatting Text with TextCursor The com.sun.star.text.TextCursor service supports all the character and paragraph properties that were presented at the start of this chapter. The following example shows how these can be used in conjunction with a TextCursor. It passes through a complete document and formats the first word of every sentence in bold type. Dim Doc As Object Dim Cursor As Object Dim Proceed As Boolean Doc = ThisComponent Cursor = Doc.Text.createTextCursor Do Cursor.gotoEndOfWord(True) Cursor.CharWeight = com.sun.star.awt.FontWeight.BOLD Proceed = Cursor.gotoNextSentence(False) Cursor.gotoNextWord(False) Loop While Proceed The example first creates a document object for the text that has just been opened. Then it iterates through the entire text, sentence by sentence, and highlights each of the first words and formats this in bold. Chapter 6 · Text Documents 77
