JavaFx：快捷键

设置方式参考：JavaFX 设置快捷键、JavaFx：11、设置快捷键、JavaFX学习：快捷键

快捷键CTRL + C

KeyCombination ctrl_c = new KeyCodeCombination(KeyCode.C, KeyCombination.CONTROL_DOWN);
window.getScene().getAccelerators().put(ctrl_c, () -> {
   System.out.println("快捷键CTRL + C");
   System.out.println(Thread.currentThread().getName());
});

或设置KeyCombination ctrl_c = new KeyCodeCombination(KeyCode.C, KeyCombination.SHORTCUT_DOWN);
监听eventFilter

window.addEventFilter(KeyEvent.KEY_PRESSED, e -> {
    //System.out.println("KeyEvent = " + e);
    if (ctrl_c.match(e)) {
        System.out.println("快捷键CTRL + C");
        System.out.println(Thread.currentThread().getName());
    }
});

快捷键CTRL + V

KeyCombination ctrl_v = new KeyCodeCombination(KeyCode.V, KeyCombination.CONTROL_DOWN);
window.getScene().getAccelerators().put(ctrl_v, () -> {
    System.out.println("快捷键CTRL + V");
    System.out.println(Thread.currentThread().getName());
});

快捷键SHIFT + C

KeyCombination shift_c = new KeyCodeCombination(KeyCode.C, KeyCombination.SHIFT_DOWN);
window.getScene().getAccelerators().put(shift_c, () -> {
    System.out.println("快捷键SHIFT + C");
    System.out.println(Thread.currentThread().getName());
});

快捷键WIN + C`（没有实现）`

win10默认启动Cortana；长按WIN后，通过eventFilter监听，点击单个字符（如C）无响应

KeyEvent.java中 isShortcutDown()、isControlDown()、isAltDown()、isShiftDown()、isMetaDown()

KeyEvent = KeyEvent [source = javafx.stage.Stage@228108b4, target = ScrollPane@16dbfdbe[styleClass=scroll-pane], eventType = KEY_PRESSED, consumed = false, character = , text = , code = WINDOWS, metaDown]
KeyEvent = KeyEvent [source = javafx.stage.Stage@228108b4, target = ScrollPane@16dbfdbe[styleClass=scroll-pane], eventType = KEY_PRESSED, consumed = false, character = , text = , code = UNDEFINED, controlDown, shortcutDown]
KeyEvent = KeyEvent [source = javafx.stage.Stage@228108b4, target = ScrollPane@16dbfdbe[styleClass=scroll-pane], eventType = KEY_PRESSED, consumed = false, character = , text = , code = ALT, controlDown, altDown, shortcutDown]
KeyEvent = KeyEvent [source = javafx.stage.Stage@228108b4, target = ScrollPane@16dbfdbe[styleClass=scroll-pane], eventType = KEY_PRESSED, consumed = false, character = , text = , code = WINDOWS, controlDown, altDown, metaDown, shortcutDown]
KeyEvent = KeyEvent [source = javafx.stage.Stage@228108b4, target = ScrollPane@16dbfdbe[styleClass=scroll-pane], eventType = KEY_PRESSED, consumed = false, character = , text = , code = SHIFT, shiftDown, controlDown, altDown, metaDown, shortcutDown]

快捷键ALT +V

KeyCombination alt_v = new KeyCodeCombination(KeyCode.V, KeyCombination.ALT_DOWN);
window.getScene().getAccelerators().put(alt_v, () -> {
    System.out.println("快捷键ALT + V");
    System.out.println(Thread.currentThread().getName());
});

快捷键CTL + ALT + C

KeyCombination ctrl_alt_c = new KeyCodeCombination(KeyCode.C, KeyCombination.ALT_DOWN, KeyCombination.CONTROL_DOWN);
window.getScene().getAccelerators().put(ctrl_alt_c, () -> {
    System.out.println("快捷键CTL + ALT + C");
    System.out.println(Thread.currentThread().getName());
});
