能在JDK7不是透明的和未修飾的JFrame使靈氣

時

看看這張圖： Transparent JFrame 能在JDK7不是透明的和未修飾的JFrame使靈氣

這裏是透明的框架代碼：

GraphicsEnvironment ge = 
     GraphicsEnvironment.getLocalGraphicsEnvironment(); 
     GraphicsDevice gd = ge.getDefaultScreenDevice(); 

     if (!gd.isWindowTranslucencySupported(TRANSLUCENT)) { 
      System.err.println(
       "Translucency is not supported"); 
       System.exit(0); 
     } 

     JFrame.setDefaultLookAndFeelDecorated(true);

這工作不錯，但試圖啓用時加入

try { 
    for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) { 
     if ("Nimbus".equals(info.getName())) { 
      javax.swing.UIManager.setLookAndFeel(info.getClassName()); 
      break; 
      } 
    } 
}catch(.......)

的LookAndFeel它給了我這個錯誤

螺紋

例外「AWT-EventQueue的 - 0」 java.awt.IllegalComponentStateException：框架裝飾

這是什麼錯誤？以及如何解決它？

感謝您的回答和建議。

'@Sri戒Chilakapati'我很抱歉，但如果你描述更多 – Azad 2013-04-25 15:50:08

我沒有得到你，我會理解的問題是，既然你在啓用透明度後設置外觀。它給出了例外，因爲靈氣不支持裝飾框架。 – 2013-04-25 16:26:25

感謝您的回答，但是'IllegalComponentStateException'告訴我該框架已經過裝飾。我使用jdk1.7.0_15和Netbeans 7.3 – Azad 2013-04-25 20:19:04

問題是在這一行'AWTUtilities.setWindowOpacity（w，0.2f）;' – Azad 2013-04-25 20:25:18

aaach你是對的[也是我的bug]（http：// stackoverflow .com/a/7261603/714968），所有適用於公共AWTUtilities.setWindowOpacity（）的代碼在Java7中都不起作用，包括未裝飾的容器 – mKorbel 2013-04-26 07:58:04

經過一番研究，我發現問題在0123之間和com.sun.awt.AWTUtilities，我認爲我們最好不要使用com.sun軟件包，除非是最後的手段，因爲它們可能會導致升級JDK版本時出現問題（它們不屬於JDK API的一部分）。

瞭解更多關於這個問題Here

From Oracle

靈氣的外觀和感覺的搖擺在JDK 6u10中引入作爲用於替代舊的金屬在低頻。使用JDK 7，Nimbus將從Oracle專有擴展名（com.sun.java.swing）中移除至標準API（javax.swing），以使其成爲真正的公民首要類Swing 。

這似乎是com.sun.awt.AWTUtilities正常工作與JDK6但雨雲LAF在JDK7。生病少我找出我的第一個問題（這是什麼錯誤）的答案，對於第二個問題（如何解決它）我必須等到新版本com.sun發佈。

我很感謝mKorbel的努力，謝謝。
