动画线程和EDT

Question

正如我在较早的文章中与Inerdia讨论的那样，
当我在某些JPanel中（肯定是EDT-
我已通过方法check进行检查）时，仍然有些奇怪，然后我调用了一些动画线程（该线程扩展Thread）以在内部启动通过检查我不在EDT上的线程。
所以我想我应该是因为动画应该在EDT上，所以我用runnable和invokeAndWait（）包装了animate方法，但是仍然在动画线程中得到了我不在EDT上的信息，同时像我之前所说的那样调用了该代码是在EDT上，所以，我的invokeLater似乎不将该动画放在EDT上？这是为什么？

相关代码（在将animate方法与runnable包装在一起并传递给以后调用：
因此，在JPanel上有一行：

Animate(trainRailRoadTrack);

实现是：

void Animate(ArrayList<RailroadSquare> i_TrainRailRoadTrack) {
    ArrayList<JPanelRailoadSquare> playerRailoadPanelsTrack = getRelevantRailroads(i_TrainRailRoadTrack);
    new SuspendedAnimation(playerRailoadPanelsTrack).start();
    jPanelBoard1.GetGameManager().EmptyPlayerSolution();
}

private class SuspendedAnimation extends Thread
{
    private ArrayList<JPanelRailoadSquare> m_PlayerRailoadPanelsTrack;

    public SuspendedAnimation(ArrayList<JPanelRailoadSquare> i_PlayerRailoadPanelTrack)
    {
        m_PlayerRailoadPanelsTrack = i_PlayerRailoadPanelTrack;
    }

    @Override
    public void run()
    {
       m_IsAnimationNeeded = true;
       for (JPanelRailoadSquare currRailoadSquare: m_PlayerRailoadPanelsTrack)
       {
           System.out.println("Is on Event dispatch thread: "+SwingUtilities.isEventDispatchThread());
           currRailoadSquare.SetGoingTrain();
           repaint();                            
           try
           {
               Thread.sleep(150);

           }
           catch (InterruptedException e){}
           currRailoadSquare.UnSetGoingTrain();
           repaint();                       
    }
}

SuspendedAnimation.run()您的内心 并不
在EDT上。那是您需要使用的地方invokeLater()，而不是在调用时Animate()：

@Override
public void run()
{
    // We're outside the EDT in most of run()
    m_IsAnimationNeeded = true;
    for (JPanelRailoadSquare currRailoadSquare: m_PlayerRailoadPanelsTrack)
    {
        SwingUtilities.invokeAndWait(new Runnable() {
            // The code that "talks" to Swing components has to be put on
            // the EDT
            currRailoadSquare.SetGoingTrain();
            repaint();
        });

        // We want to keep sleeping outside the EDT.
        try
        {
            Thread.sleep(150);
        }
        catch (InterruptedException e){}

        SwingUtilities.invokeAndWait(new Runnable() {
            currRailoadSquare.UnSetGoingTrain();
            repaint();                       
        }
    }
}
