java - SwingUtilities.invokeLater ...有一个invokeNow吗？

Question

I had a problem earlier我试图将对象添加到 Canvas 中，但 SwingUtilities.invokeLater 尚未真正完成其工作。我确实需要能够可靠地向此 JPanel 添加内容，但我不断遇到同样的错误。下面的代码有更好的替代方案吗？

private void startNewGame() {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            gameFrame = new InvadersGameFrame();
        }
    });
}

参见SwingUtilities.invokeAndWait(Runnable)其中:

Causes doRun.run() to be executed synchronously on the AWT event dispatching thread. This call blocks until all pending AWT events have been processed and (then) doRun.run() returns. This method should be used when an application thread needs to update the GUI.
