On Event Dispatch Thread---want to get off of it

问题:

Suppose that a method I own is sometimes called on the Event Dispatch Thread and is sometimes not. Now suppose some of the code in that method I want to have called on a thread other than the Event Dispatch Thread.

Is there a way to run some code on a thread other than the EDT at this point?

I tried this:

        if (SwingUtilities.isEventDispatchThread()) {
            new Runnable() {
                @Override
                public void run() {
                    myMethod();
                }
            }.run();
        } else {
            myMethod();
        }

But myMethod() ended up running on the EDT even when I created a new Runnable.

Is there a way to run myMethod() on a thread other than the EDT at this point?

回答1:

You doing it just fine. But your Runnable has to be pass to a new Thread.

e.g.

new Thread(new Runnable() {
 @Override
 public void run() {
     myMethod();
 }
}).start();

Please note that invoking the "run()" method won't start a new Thread. Use start() instead.
