如果您这样做的话，那只是鸡/蛋。您可以在EDT上构造所有Swing对象，然后SwingWorker通过指示EDT通过执行它们来让您（或任何其他线程）管理所有更新SwingUtilities.invokeLater(Runnable)。

        button.addActionListener(new ActionListener() {

                task.execute();
            }
        });

        setSize(200, 200);
        setLocationRelativeTo(null);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override

                    dialog.setVisible(true);
                }
            });

            int progress = 0;
            for (int i = 0; i < 5; i++) {
                Thread.sleep(1000);
                setProgress(progress += 20);
            }

            return null;
        }

        @Override
        protected void done() {
            dialog.setVisible(false);
            dialog.dispose();

如果您担心invokeLater实现（内部SwingWorker.doInBackground）在执行之后会被执行SwingWorker.done，只需将代码done放入另一个invokeLater。通过这样做，您可以将Runnable实现排入队列以让EDT以特定顺序执行它们。即使从EDT本身调用此方法，也会发生排队。

请注意，如果您看一下SwingWorker实现，您会看到它依赖于javax.swing.Timer执行done()和Timer本身调用invokeLater，因此done再次在内部调用它无济于事。但是，如果这样做，不会有任何问题。
