將JFrame設置爲透明使得所有的JComponet在Linux中都是透明的

我希望我的JFrame透明。我使用下面的代碼使其透明。它在Windows上運行良好，但在Linux上使所有JComponet透明。將JFrame設置爲透明使得所有的JComponet在Linux中都是透明的

這裏是JFrame的上窗口的外觀和linux Here is the look on windows and linux

我的代碼：

    initComponents();  

    jLabel1.setIcon(new ImageIcon(getClass().getResource("device_pc.png"))); 

}

嘗試並添加到JPanel上，並將面板不透明設置爲false，看看會發生什麼。 –

試過。但沒有運氣。 – user3289782

測試[this out]（http://stackoverflow.com/a/21771615/2587435）看看這隻鳥是否是透明的 –

只是一個想法，爲什麼不設置JButtons在晦澀真，比如果不工作，給他們每個人一個BG/FG顏色（也許使用自定義顏色，將alpha值設置爲100等）。

祝你好運！

Linux是最好的。
