Swing：按下ESC键时如何关闭对话框？

Swing：按下ESC键时如何关闭对话框？

使用

InputMap

和

ActionMap

处理Swing中的关键 *** 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     ); }
