Redraw GUI Prior Thread.Sleep

Question

我認爲這對我來說會簡單很多，但我錯過了這個概念。簡而言之，我提出了一種淡化音頻的方法，並使用Thread.Sleep讓它在for循環中「等待」。在調用該方法之前，我將幾個標籤和文本字段設置爲不可見，但它們一直等到線程休眠改變之後。我試圖將標籤封裝在一個do-while循環中強制它們，甚至試圖在它之後調用重繪，但它沒有解決任何問題。任何意見，將不勝感激：

編輯，包括的actionPerformed：

  public void actionPerformed(ActionEvent e) 
    { 
     if(e.getSource() == quit) 
     { 
      System.exit(0); 
     } 
     else if(e.getSource() == play) 
     { 
      System.out.println("PLAY"); 
      quit.setVisible(false); 
      quit.setEnabled(false); 
      play.setVisible(false); 
      play.setEnabled(false); 
      GameActivated(); 
     } 
     else if(e.getSource() == submitTeams) 
     { 
      teamOneName = teamOneTF.getText(); 
      teamTwoName = teamTwoTF.getText(); 

      Swinpublic void actionPerformed(ActionEvent e) 
    { 
     if(e.getSource() == quit) 
     { 
      System.exit(0); 
     } 
     else if(e.getSource() == play) 
     { 
      System.out.println("PLAY"); 
      quit.setVisible(false); 
      quit.setEnabled(false); 
      play.setVisible(false); 
      play.setEnabled(false); 
      GameActivated(); 
     } 
     else if(e.getSource() == submitTeams) 
     { 
      teamOneName = teamOneTF.getText(); 
      teamTwoName = teamTwoTF.getText(); 

      SwingUtilities.invokeLater(new Runnable(){ 
       public void run(){ 
           teamOneLabel.setVisible(false); 
           teamOneTF.setVisible(false); 
           teamTwoLabel.setVisible(false); 
           teamTwoTF.setVisible(false); 
           submitTeams.setVisible(false); 
       } 
       }); 

     } 
     else 
      System.out.println("Error: Button pressed with no known source."); 
    } 

下面是AudioHandler1內部所調用：

  for(int count = 0; count < 71; count++) 
     { 
      gainControl.setValue((float) count*-1); 
      System.out.println("Waiting!" + Math.random()); 
      try 
       { 
       Thread.sleep(50); 
       } 
      catch(InterruptedException ex) 
       { 
        Thread.currentThread().interrupt(); 
       } 

     }

您在這裏堵EDT。使用SwingWorker到invokle AudioHandler1

 new SwingWorker<Void,Void>() 
     { 
     @Override 
     protected Void doInBackground() throws Exception 
      { 
      AudioHandler1("Theme.wav",false,true); 
      return null; 
      } 
     }.execute();
