(resend, using my subscribed email address this time) Just for clarification: My understanding from Pete's mail was that we would talk about the line number valid for a single object, not for a document. And that it doesn't matter whether or not the app has visualization for line numbers.
So if you have a text document with two paragraphs in OOo (which are single text objects), each caret pos 0 from each paragraph would again report line number 1. We already introduced such API in UAA, but probably after IBM taking it as a template for IA2 ;) > http://api.openoffice.org/docs/common/ref/com/sun/star/accessibility/XAccessibleMultiLineText.html IIRC, this was needed to implement some NsAccessibility API. The both "special" functions with the Caret might look strange to you, because you might thinks that one could simply ask for the caret position and use it. The reason is that there is some special handling with automatic line breaks. If you have "AAA BBB", and BBB is in line 2, the caret behind the blank will normally be shown in line 2 when typing or traveling with the cursor, except you are in line 1 and press END. And wrt James's comment that it should be for pieces of text rather than just the caret - doesn't make sense to me. You might avoid one function call, but API would look quite strange then. HTH, Malte.
