TAB鍵

Question

我看到兩個問題的Java代碼，希望用戶按TAB鍵，當代碼在Chrome運行作爲applet

首先，貌似沒有被發現的新聞。

更多nastily在IE9按TAB失去焦點的小程序完全。

我已經看到這些報道過，但我的搜索，到目前爲止，如果有一個解決方案並沒有提出很好地解決，甚至是一個快速的答案......不是嗎？

運行作爲桌面或在webstart/JNLP應用TAB效果很好，只在小程序它會導致混亂。

Answer 2

public void init() 
    { 
     Container topParent = null; 
     Container parent = this; 
     // The natural thing would be to call getParent() until it returns 
     // null, but then you would be looping for a long time, since 
     // PluginEmbeddedFrame's getParent() returns itself. 
     for (int k=0; k < 10; k++) { 
      topParent = parent; 
      parent = parent.getParent(); 
      if (parent == null) break; 
     } 

     // If topParent isn't a KeyEventDispatcher then we must be in some 
     // Plugin version that doesn't need the workaround. 
     try { 
      KeyEventDispatcher ked = (KeyEventDispatcher)topParent; 
      KeyboardFocusManager kfm = KeyboardFocusManager.getCurrentKeyboardFocusManager(); 
      // You have to remove it twice, otherwise the problem isn't fixed 
      kfm.removeKeyEventDispatcher(ked); 
      kfm.removeKeyEventDispatcher(ked); 
     } catch (ClassCastException e) {} 
    }
