How to detect if applet lost its focus

Question

is there a possible way to detect if the applet( the browser itself) lost its focus?
ANYONE??????????

Answer 1

it doesnt work for me because i am not using a frame. the applet is embedded in the browser itself.
You're right. i need to use JSObject to call javascript from java. But i'm still having some problems.
win = JSObject.getWindow(this);
str = (String)applet.win.call("myEval", obj);     
the str should return a 'false' if the applet is out of focus and 'true' if the applet is in focus.
This is my javascript:
<script type = "text/javascript">
var winstate = 'true';
function myEval() {
     window.onblur = returnFalse();
     return winstate;
function returnFalse(){
     winstate = 'false';     
function returnTrue(){
     winstate = 'true';
</script>
you know what happens? it always returns 'false' even though the applet is in focus! i don't understand what am i doing wrong. Please help. I am stuck on this.
