EventQueue.push / pop methods

Question

Hi,
I'm implementing a method, which must return data. The data is calculated by a SwingWorker. The method is called by the AWT dispatch thread. The SwingWorker runs EventQueue.invokeLater() now and then to generate a progress dialog.
I call SwingWorker.get() inside the method, but this freezes up the GUI. So... I do
    private static class MyEventQueue
        extends EventQueue
        public MyEventQueue()
            super();
        @Override
        public void pop()
            super.pop();
    int[] method()
        SwingWorker<int[], Void> worker = new SwingWorker<int[], Void>(){
            @Override
            protected int[] doInBackground()
                /* do stuff */
       worker.execute();
        MyEventQueue queue = new MyEventQueue();
        Toolkit.getDefaultToolkit().getSystemEventQueue().push(queue);
        try {
            return worker.get();
        }catch (ExecutionException e){
            throw new Exception();
        }catch (InterruptedException e){
            throw new Exception();
        }finally{
            queue.pop();
    }... and it works! The events generated by the SwingWorker get fired. I want to know, is this recommended?
Is it dangerous? What could go wrong?
Thanks,
Jesse

Answer 1

Yes, normally I would, but... My method needs to block until all data is received, and then return all data. This is not optional, and when blocking (even using the process and publish methods and blocking until all data is received), I hold up the dispatch thread. So, I cant use publish and process. (Or, I can, but I have the same problem as get()).
