※ 引述《seruze (seruze)》之铭言： : 是这样的~ : 在我开启一个视窗後~ : 我想在关闭他时，同时可以执行一动作。 : 这样子的做法，我可以设一个「关闭」的BUTTON~ : 先执行我要的内容，然後再用JFrame.dispose();关闭他~ : 可是视窗右上角也有一个「x」的关闭按钮~ : 请问各位大大这时候，我该怎麽定义按「x」时会执行的动作呢？ api: http://0rz.tw/744ob jframeInst.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 这是预设的状况 按了就关闭 有三种选项可以选 DO_NOTHING_ON_CLOSE (defined in WindowConstants): Don't do anything; require the program to handle the operation in the windowClosing method of a registered WindowListener object. HIDE_ON_CLOSE (defined in WindowConstants): Automatically hide the frame after invoking any registered WindowListener objects. DISPOSE_ON_CLOSE (defined in WindowConstants): Automatically hide and dispose the frame after invoking any registered WindowListener objects. EXIT_ON_CLOSE (defined in JFrame): Exit the application using the System exit method. Use this only in applications. 如果想要自己定义更多的行为 实做一个 WindowListener 并复写 windowClosing 就可以做到 记得以前在板上写过范例 , 不过大概标题下得太烂, 现在一时找不到... api: http://0rz.tw/dc4iv -- API Document will be your friend ...:) -- I am a person, and I am always thinking . Thinking in love , Thinking in life , Thinking in why , Thinking in worth. I can't believe any of what , I am just thinking then thinking , but worst of all , most of mine is thinking not actioning... --
