將標題欄添加到JFrame（Linux）

我試圖添加一個帶有「X」按鈕的標題欄到應用程序。我已閱讀關於Look &感受Java，但我不知道我缺少什麼（我剛剛創建了一個桌面應用程序，添加了一個JFrame表單，並拖動了一個表格 - 沒有任何邏輯）。將標題欄添加到JFrame（Linux）

請按[sscce]（http://www.sscce.org）更改按鈕數量（對於Top-Level Containers）。默認情況下，'JFrame'實例將有一個標題欄，除非['setUndecorated（true）']（http://docs.oracle.com/javase/6/docs/api/java/awt/Frame.html# setUndecorated％28boolean％29）在*實現*之前被調用。 – mre 2012-01-11 20:12:45

對不起。編輯的問題。 – uluroki 2012-01-11 20:39:19

hmmm本機操作系統相關問題例如http://www.pendrivelinux.com/ubuntu-desktop-effects-fixing-the-missing-titlebar/ – mKorbel 2012-01-11 21:27:25

I just created a Desktop Application, added a JFrame Form, 
and dragged'n'dropped some buttons - no logic yet

有這些標準Top-Level Containers

JFrame - >已經有三個按鈕最小化，最大化和關閉

JDialog - >已接近只有一個按鈕

JWindow - >默認沒有裝飾，沒有任何按鈕

基本上沒有任何按鈕更改另一個Look & Feel
