Hi Everyone,

Iam new in using text editors.Iam using the below snippet to update my
editor.

IDocumentProvider dp = editor.getDocumentProvider();
IDocument doc = dp.getDocument(editor.getEditorInput());
int offset = doc.getLineOffset(doc.getNumberOfLines()-4);

I want to get hold of a character say in a nth position of a row and
update it.

can i get hold of individual characters in a row ..?

Best Regards,
Michael

Take a look at the methods in IDocument.

i want to insert a empty line after every line.
Iam trying it using replace as there is no insert method provided.Iam
iterating through all the lines in the editor and after every line iam
trying to insert a empty line,but i do not want that empty line to be
treated as a separate line as editor does.How do i need to avoid this..?
and for the empty line when ever i say
getlinelength(int offset) it returns 1 eevnthough it is empty..?

Thanks in advance
Michael

As said before: read the Javadoc of IDocument, e.g.

/**
* Returns the length of the given line including the line's delimiter.
*
* @param line the line of interest
* @return the length of the line
* @exception BadLocationException if the line number is invalid in
this document
*/
int getLineLength(int line) throws BadLocationException;
