I've got a thread dump of an applet running on JVM 1.6.0_12 in Opera 9.64 Build 10487 - and it shows three event queues! As far as I know the Java Swing event handling is single threaded - did this change in any recent update?

And I suspect that the event queue you speak of is the OS's event queue, which isn't likely to accessible from a browser, if at all.

Hi all,
Does anybody know how to add an event in the head of the queue for concrete event type?
I.e. I have already defined onclick event. A want to add additional call back function, that will be invoked BEFORE already defined callback.
Thanks in advance...

I would like to create a class whose methods can be called from multiple threads. but instead of executing the method in the thread from which it was called, it should perform them all in it's own thread. No result needs to be returned and It shouldn'...

I have a "MessageQueue" class. It's just is to queue messages. Beans that need the ability to post messages simply have a MessageQueue property and Spring takes care of injecting it.

So what I want to do is to coordinate some effects using jQuery for some AJAX calls that I'm working with. My problem is that the fadeIn for the second div fires at the same time with the fadeOut for the first div.
