I had problems with this too... I finally sorted it out though;
1/ the referance is; this.item.x / y
2/ It must be called from within the applet <My Applet> class NOT
<Other> class used by <My Applet>.
3/ To do that you must pass 'this' to your <other> class as its parent.
4/ That means the referance is now; parent.item.x / y
What I have not sorted out yet, is the fact that this will not take into
account use of the browser scroll bar. There are variables scrollX / Y in
the browser displayItemWindow but these are protected. There is a getScrollY
method but I have not looked at it yet.
The other problem with this is the co-ord's returned from the mouse pointer
have an origin with the applet and these take scroll into account.
A real mess but from talking to Jonathan Payne he helped me sort it out and
has told me it will all be sorted out with the beta awt. The other thing to
bare in mind is any solution to this using an alpha, will be proprietry.
