在Java中集成BreezyGUI和控制鍵

我正在創建一個使用事件驅動編程和動態運動（對於導彈等）組合驅動的飛行模擬器。目前，我有一個使用keyListener接口和非常嘲諷的if-else命令結構的單人遊戲。如果我按下一個按鍵，這將起作用，但如果我按下第二個按鍵，則第一個按鍵執行的操作將停止。我試圖用鍵綁定來解決這個問題，但是，我使用快速的GUI來創建遊戲窗口，並且找不到將keyBindings直接應用於BreezyGUI框架的方法。我也避免嘗試將按鍵綁定到按鈕和文本字段，因爲它們可能會造成焦點問題。在Java中集成BreezyGUI和控制鍵

有沒有辦法將KeyBindings直接綁定到BreezyGUI框架，如果沒有，我該如何繼續？如果我的解釋不充分，請參閱下面的縮略代碼。

----------------- UPDATE ------------------------- ------------

以下Hovercraft的答案我把這段代碼放在我的paint方法中。它似乎沒有工作。

if (Plane.getPlanes().indexOf(flyer) == - 1) // Until I find a better solution... 
     {  
      Plane.addPlane(flyer); 
      JPanel panel = new JPanel(); 
      add(panel); 
      panel.getInputMap().put(KeyStroke.getKeyStroke("1", "doSomething"); 
      panel.getActionMap().put("doSomething", new anAction()); 

     }

class anAction extends AbstractAction 
{           
    public void actionPerformed(ActionEvent event) 
    { 
     TrackingBot.botMania(); 
    }  
}
