使用
InputMap和
ActionMap处理Swing中的关键操作。要干净地关闭对话框，请向其发送一个关闭窗口事件。
从我的博客：
private static final KeyStroke escapeStroke = KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0); public static final String dispatchWindowClosingActionMapKey = "com.spodding.tackline.dispatch:WINDOW_CLOSING"; public static void installEscapeCloseOperation(final JDialog dialog) { Action dispatchClosing = new AbstractAction() { public void actionPerformed(ActionEvent event) { dialog.dispatchEvent(new WindowEvent( dialog, WindowEvent.WINDOW_CLOSING )); } }; JRootPane root = dialog.getRootPane(); root.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put( escapeStroke, dispatchWindowClosingActionMapKey ); root.getActionMap().put( dispatchWindowClosingActionMapKey, dispatchClosing ); }
