[Solved] Get last Writer paragraph using XParagraphCursor

[othmanelmoulat]

How can i get the last Writer paragraph text string using the XParagraphCursor ?

in my below code it seems the XParagraphCursor doesn't get effect. it doesn't work and the printed string is empty.

Code: Select all

        XText xText = xTextDocument.getText();
        XTextCursor curText = xText.createTextCursor();         
        
        // Position the cursor in the second paragraph
           // Get the XParagraphCursor interface of the document cursor
        
          XParagraphCursor xParaCursor = (XParagraphCursor)
             UnoRuntime.queryInterface( XParagraphCursor.class, curText );
          //curText.gotoEnd ( false );
         xParaCursor.gotoEnd(true);
         xParaCursor.gotoEndOfParagraph( true );
         log.println(xParaCursor.getString());

I recorded some code using MRI that creates a text cursor, moves to the end and gets the string.

Code: Select all

import com.sun.star.text.XSimpleText;
import com.sun.star.text.XText;
import com.sun.star.text.XTextCursor;
import com.sun.star.text.XTextDocument;
import com.sun.star.text.XTextRange;
import com.sun.star.uno.UnoRuntime;

static public void snippet(Object oInitialTarget)
{
	XTextDocument xTextDocument = UnoRuntime.queryInterface(
		XTextDocument.class, oInitialTarget);
	XText xText = xTextDocument.getText();
	
	XSimpleText xSimpleText = UnoRuntime.queryInterface(
		XSimpleText.class, xText);
	XTextCursor xTextCursor = xSimpleText.createTextCursor();
	
	xTextCursor.gotoEnd(true);
	
	XTextRange xTextRange = UnoRuntime.queryInterface(
		XTextRange.class, xTextCursor);
	String sString = xTextRange.getString();
	
}

I hope that helps.

Thank you. i tried this code but it seems it returns the whole document text not only the last paragraph text. maybe my document is not well formated? i have attached my odt file. but if i use your code the whole text of the document is returned.

Hi,

1. Go to the end of the text, with expand parameter false.
2. Then go to the start of the paragraph, with expand parameter true, so the cursor covers the whole paragraph range.

Code: Select all

xTextCursor.gotoEnd(false);
xParaCursor.gotoStartOfParagraph(true);

thank you this works perfectly.
I have a question regarding the paragraph cursor and also the PageCursor: do they actually move the document cursor visually? i tested that the PageCursor.jumpToEnd() did have the effect of moving the cursor to the end of document. my question can we have the logic effect of the cursor without actually moving the document cursor visually? so that the user doesn't have the annoyance of a cursor moving without his interaction? in fact i want to get the number of pages in my document and used a PageCursor for that but it has the disadvantage of moving the cursor to end of document which is a nuisance i want to avoid.

thank you

Surely you could make the program store the cursor position at the beginning of the operation and revert to that stored position at the end?

yes i did that but it stils gives this visual nuisance of a cursor moving forth and back. it is not very perceivable and can live with it. However it would be better to have the feature of navigating the OO document with a logical cursor that doesn't actually moves the cursor visually but only logically so that the programmer can do useful document navigation without the nuisance of a cursor moving visually. a Boolean flag would be sufficient so that it indicates whether to move cursor both logically and visually. This could be a good feature to be added to the OOo API.
other than the cursor api are there any other techniques to navigate the document programatically behind the scene?

thanks

question regarding the paragraph cursor and also the PageCursor: do they actually move the document cursor visually? i tested that the PageCursor.jumpToEnd() did have the effect of moving the cursor to the end of document.

As usual, answers are in the Developer's Guide (but you have to read it again and again).
See page Navigating, first section : Cursors.

The text model cursor allows for free navigation over the model by character, words, sentences, or paragraphs. There can be several model cursors at the same time.
(...)
The text view cursor enables the user to travel over the document in the view by character, line, screen page and document page. There is only one text view cursor. Certain information about the current layout, such as the number of lines and page number must be retrieved at the view cursor.

The text model cursor is described in page Editing Text.

couldn't locate the developers guide section that talks about the text model cursor. they talsk abourt a certain text model cursor but they gave no example if i'm not wrong.. but thanks anyway.
