RE: need advices and help about Bookmark API.

[LORENZO Vincent]

Hello everybody,
I thank you for your anwsers. I will continue with Bookmark which seem me quite 
easy to implement.

I found a way to avoid to search the text in the document:
 short value = ((Integer) text.length()).shortValue();
 cursor.setString(text);
   cursor.gotoEnd(false);

 cursor.goLeft(value, false);
 InsertBookmark(odtEditor.getXTextDocument(), cursor, 
"muBookmarkName");
   cursor.gotoEnd(false);

It seems work find.

Hallo,
We did some test to use RDF (also Miklos his advice) to store some information 
about images in a Writerdoc, before we stored the information in the 
ImageObject , what was not a good idea.

Bookmark is just a string; one hack you can do is to give it a unique
name, which refers to a per-document custom metadata, where the value
disturbs the user less. But that's still just a string, so you need to
serialize/load to/from string if you want to store key-value pairs.

An alternative is to use RDF annotations, which allows more complex
structures:

https://wiki.openoffice.org/wiki/Documentation/DevGuide/OfficeDev/RDF_metadata

(Though you need to use archive.org or something like that to access it,
seems the Apache site is currently not available.)

One shortcoming of RDF is that it's ODF-only; while the per-doc custom
metadata + bookmarks works with most other formats as well.



So, in this example, I write text, I look for it, then I create a XTextRange 
and at the end, I can create the Bookmark. I'm not very have happy with this 
solution. I would prefer a solution without the search step, but I don't know 
how to get a valid XTextRange (I admit I don't yet well understand  the 
behavior of the API).
Please, do you have

Some kind of iteration or search is necessary: if you take the user's
current selection or you iterate to the nth paragraph or you search for
text is up to you. An XTextRange is just a selection (where start and
end may point to the same document model position).

Hope this helps. :-)
