JDK自带了Robot类，此类用于为测试自动化、自运行演示程序和其他需要控制鼠标和键盘的应用程序生成本机系统输入事件。Robot 的主要目的是便于 Java 平台实现自动测试。

例子：打开win7的任务管理器，快捷键是ctrl+shift+esc

Each such listener object * gets this <code>KeyEvent</code> when the event occurs. * <p> * <em>"Key typed" events</em> are higher-level and generally do not depend on * the platform or keyboard layout. They are generated when a Unicode character * is entered, and are the preferred way to find out about character input. * In the simplest case, a key typed event is produced by a single key press * (e.g., ‘a‘). Often, however, characters are produced by series of key * presses (e.g., ‘shift‘ + ‘a‘), and the mapping from key pressed events to * key typed events may be many-to-one or many-to-many. Key releases are not * usually necessary to generate a key typed event, but there are some cases * where the key typed event is not generated until a key is released (e.g., * entering ASCII sequences via the Alt-Numpad method in Windows). * No key typed events are generated for keys that don‘t generate Unicode * characters (e.g., action keys, modifier keys, etc.). * <p> * The getKeyChar method always returns a valid Unicode character or * CHAR_UNDEFINED. Character input is reported by KEY_TYPED events: * KEY_PRESSED and KEY_RELEASED events are not necessarily associated * with character input. Therefore, the result of the getKeyChar method * is guaranteed to be meaningful only for KEY_TYPED events. * <p> * For key pressed and key released events, the getKeyCode method returns * the event‘s keyCode. For key typed events, the getKeyCode method * always returns {@code VK_UNDEFINED}. The {@code getExtendedKeyCode} method * may also be used with many international keyboard layouts. * * <p> * <em>"Key pressed" and "key released" events</em> are lower-level and depend * on the platform and keyboard layout. They are generated whenever a key is * pressed or released, and are the only way to find out about keys that don‘t * generate character input (e.g., action keys, modifier keys, etc.). The key * being pressed or released is indicated by the {@code getKeyCode} and {@code getExtendedKeyCode} * methods, which return a virtual key code. * * <p> * <em>Virtual key codes</em> are used to report which keyboard key has * been pressed, rather than a character generated by the combination * of one or more keystrokes (such as "A", which comes from shift and "a"). * * <p> * For example, pressing the Shift key will cause a KEY_PRESSED event * with a VK_SHIFT keyCode, while pressing the ‘a‘ key will result in * a VK_A keyCode. After the ‘a‘ key is released, a KEY_RELEASED event * will be fired with VK_A. Separately, a KEY_TYPED event with a keyChar * value of ‘A‘ is generated. * * <p> * Pressing and releasing a key on the keyboard results in the generating * the following key events (in order): * <PRE> * {@code KEY_PRESSED} * {@code KEY_TYPED} (is only generated if a valid Unicode character could be generated.) * {@code KEY_RELEASED} * </PRE> * * But in some cases (e.g. auto-repeat or input method is activated) the order * could be different (and platform dependent). * * <p> * Notes: * <ul> * <li>Key combinations which do not result in Unicode characters, such as action * keys like F1 and the HELP key, do not generate KEY_TYPED events. * <li>Not all keyboards or systems are capable of generating all * virtual key codes. No attempt is made in Java to generate these keys * artificially. * <li>Virtual key codes do not identify a physical key: they depend on the * platform and keyboard layout. For example, the key that generates VK_Q * when using a U.S. keyboard layout will generate VK_A when using a French * keyboard layout. * <li>The key that generates {@code VK_Q} when using a U.S. keyboard layout also * generates a unique code for Russian or Hebrew layout. There is no a * {@code VK_} constant for these and many other codes in various layouts. These codes * may be obtained by using {@code getExtendedKeyCode} and are used whenever * a {@code VK_} constant is used. * <li>Not all characters have a keycode associated with them. For example, * there is no keycode for the question mark because there is no keyboard * for which it appears on the primary layer. * <li>In order to support the platform-independent handling of action keys, * the Java platform uses a few additional virtual key constants for functions * that would otherwise have to be recognized by interpreting virtual key codes * and modifiers. For example, for Japanese Windows keyboards, VK_ALL_CANDIDATES * is returned instead of VK_CONVERT with the ALT modifier. * <li>As specified in <a href="../doc-files/FocusSpec.html">Focus Specification</a> * key events are dispatched to the focus owner by default. * </ul> * * <p> * WARNING: Aside from those keys that are defined by the Java language * (VK_ENTER, VK_BACK_SPACE, and VK_TAB), do not rely on the values of the VK_ * constants. Sun reserves the right to change these values as needed * to accomodate a wider range of keyboards in the future. * <p> * An unspecified behavior will be caused if the {@code id} parameter * of any particular {@code KeyEvent} instance is not * in the range from {@code KEY_FIRST} to {@code KEY_LAST}. * * @author Carl Quinn * @author Amy Fowler * @author Norbert Lindenberg * * @see KeyAdapter * @see KeyListener * @see <a href="http://java.sun.com/docs/books/tutorial/post1.0/ui/keylistener.html">Tutorial: Writing a Key Listener</a> * * @since 1.1 */ public class KeyEvent extends InputEvent { /** * Stores the state of native event dispatching system * - true, if when the event was created event proxying * mechanism was active * - false, if it was inactive * Used in Component.dispatchEventImpl to correctly dispatch * events when proxy is active */ private boolean isProxyActive = false; /** * The first number in the range of ids used for key events. */ public static final int KEY_FIRST = 400; /** * The last number in the range of ids used for key events. */ public static final int KEY_LAST = 402; /** * The "key typed" event.
