know if somebody finds nicer solution.
public native int getSelectionStart(Element elem)/*-{
return
elem.contentWindow.getSelection().getRangeAt(0).startOffset;
}-*/;
public native int getSelectionLength(Element elem)/*-{
return
elem.contentWindow.getSelection().getRangeAt(0).toString().length;
}-*/;
public native int getSelectionStartNode(Element elem)/*-{
var
node=elem.contentWindow.getSelection().getRangeAt(0).startContainer;
if(node.parentNode.nodeName != 'BODY')
{
node = node.parentNode;
}
var nodes = node.parentNode.childNodes;
i = 0;
while(node.previousSibling != null)
{
node = node.previousSibling;
i++;
}
return i;
}-*/;

undestart why on getSelectionStartNode you start counting nodes, and
not retrieve the node as Element right away.
But as said AFAIK there is no interface to get/set the cursor
position.

just updated the source on google projects to reflect the latest
status, normally from day to day work I use a private local svn
repository.
I realize its difficult to drop into a alpha-status project, as oposed
to this in release state projects you normally start by using it, and
enhancing it for a specific need. Also its not my style to tell anyone
what to do, there are just so many things to change/enhance, in fact a
friend of mine every week he comes with another idea whats now
possible to do with this widget, what wasn't possible before. Right
now I'm working on block/selection/copy/paste/clipboard support,
together with an undo/redo machanism its IMHO the last step to be a
useful text editor at least.
Also important to note what I'm proud of, altough a monospaced font is
now default, is it works not only with monospaced fonts but also with
dynamic ones.
Things on the general TOWISH list are:
* Opera support (right now only the issues with Firefox and IE are
handled, I chose these 2 as the majority of the market, and not
depending on any browser specific enhancements)
* Safari support, I I have not right now easy access to a safari
browser, and well other reasons see opera.
* RichText support:
** Bold, Italic, Colored fonts, Links, Other font style/size etc.
** Table editing
** Inline picture support
on the other side than the WYSIWYG path is:
* a syntax highliting for diverse languages like java/javascript/c/
etc.
* spellchecking. Obviously we can't expect the client to hold the
dictionary, so a AJAX mechanism would make sense, having the server
checking spelling in background.
* Exception handling: bad stuff happens, it would be wishable to catch
all exceptions, and provide the user a feedback, why the application
stopped working properly, and having an option to try to retrieve his
work in progress.
* Integration of AceArea in wikipedia as user script
* optimize the cursor position finding algorithmn
and so on, generally I take "customizeable" seriously and constructed
the whole thing with an internal message handling, so it should be
able for users to extend without having to change the widget code
itself, however its alway possible to do so! As possible extensions I
have my own "big picture" of e.g. collaberative editing, wiki
integration in the editor etc.
also I try to take documentation seriously, starting with trying to do
good source code comments. There isn't yet a "big picture"
documentation, but if you don't understand something I gladly expalin
it, and use the opportunity to document it at the same moment.

Because:
1) I have very limited knowledge on javascript.
2) I need to know the selection start relating to the document and not
the node (startContainer).
I would be very happy if you could show me simpler way of doing this..

you're probably on Windows machine so you can use Safari 3.0 beta for
Windows and WebKit nightly builds:
http://nightly.webkit.org/
I'm using it for testing on Windows machine when I'm off of my mac
(WebKit has really decent inspector tool you could find useful to gif
your html layout and other things at runtime),

is linux, the last time I tried out some Safari clone for windows, it
was pretty unusable.
After all at my university they have 1 computer lab with Macs I just
have to _go_ there and try out if AceArea works, respectavely what
doesn't work. It's on the TODO list ;-)
