动画线程和 EDT

正如我在 之前的文章中与 Inerdia 讨论的那样< /a>,
事情仍然很奇怪当我在一些 JPanel 中(肯定是 EDT - 我用方法检查进行了检查)然后我调用一些动画线程(线程扩展线程)来启动时,在线程内部我没有通过检查进入 EDT .
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,但仍然在动画线程中得到了我不在 EDT 上的信息,同时调用了我之前所说的代码是在 EDT 上,所以,我的 invokeLater 似乎没有将该动画放在 EDT 上?这是为什么?

相关代码(在用 runnable 包装 animate 方法并传递给稍后调用之前:
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();                       
    }
}

As I discussed with Inerdia on the earlier post,
something is still strange When I'm in some JPanel (EDT for sure-I checked with the method check) and then I call some animation thread(the thread extend Thread) to start, inside the thread I'm not on EDT by check.
So I guess I should be because animation should be on EDT, so I wrapped the animate method with runnable and invokeAndWait(), but still got that in the animation thread I'm not on EDT, while calling to that code as I said earlier is on EDT, so, my invokeLater seems not to place that animation on EDT? why is that?

Relevant code(before wrapping the animate method with runnable and passing to invoke later:
So, being on a JPanel there is a line:

Animate(trainRailRoadTrack);  

Implementation is:

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();                       
    }
}

SuspishedAnimation.run() 内部,您不在 EDT 上。这就是您需要使用 invokeLater() 的地方,而不是在调用 Animate() 时:

@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();                       
        }
    }
}

Inside of SuspendedAnimation.run() you're not on the EDT. That's where you need to use invokeLater(), not when calling 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();                       
        }
    }
}
