動畫線程和EDT

Question

正如我Inerdia在earlier post討論，
的東西仍然是奇怪，當我在一些JPanel的是（EDT肯定，我用的方法檢查中檢查），然後我把一些動畫線程（線程擴展線程）啓動，在線程內我不通過檢查EDT。
所以我想我應該是因爲動畫應該是美國東部時間，所以我包裹着的可運行和invokeAndWait（）的動畫的方法，但還是得到了在動畫線程我不是EDT，同時呼籲該代碼爲我之前說過在美國東部時間，所以，我的invokeLater似乎不把這個動畫放在EDT上？這是爲什麼？

相關的代碼（具有可運行包裹動畫的方法和通過稍後調用之前：
所以，正對一個JPanel有一行：

Animate(trainRailRoadTrack); 

實施是：

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();      
    } 
} 

Answer 1

在SuspendedAnimation.run()內部，你在而不是上。這就是你需要使用invokeLater()的地方，而不是在致電Animate()時：

@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();      
     } 
    } 
}
