在关注TextField时，CTRL + C不起作用

Question

这是我在JavaFX中为ctrl + c组合设置操作的代码。当关注TextField command_line时，它不起作用。为什么呢？

public void setCtrlC() {
    command_line.getScene().getAccelerators().put(new KeyCodeCombination(KeyCode.C, KeyCombination.CONTROL_ANY),
            new Runnable() {
                @Override
                public void run() {
                    LOGGER.debug("CTRL+C pressed");
                    try {
                        if (tab_toradex.isSelected()) {
                            bw.write(3);
                            bw.flush();
                        }
                        if(tab_novatel.isSelected()){
                            bw2.write(3);
                            bw2.flush();
                        }
                    } catch (IOException e) {
                        LOGGER.debug("CTRL+C command failed");
                    }
                }
            });
}

谢谢！

好的，用这个解决了：

final KeyCombination keyCombinationShiftC = new KeyCodeCombination(KeyCode.C, KeyCombination.CONTROL_DOWN);

public void setCtrlC() {

    command_line.setOnKeyPressed(new EventHandler<KeyEvent>() {

        @Override
        public void handle(KeyEvent event) {
            if (keyCombinationShiftC.match(event)) {
                LOGGER.debug("CTRL+C pressed");

                try {
                    if (tab_toradex.isSelected()) {
                        bw.write(3);
                        bw.flush();
                    }
                    if(tab_novatel.isSelected()){
                        bw2.write(3);
                        bw2.flush();
                    }
                } catch (IOException e) {
                    LOGGER.debug("CTRL+C command failed");
                }
            }
        }
    });
}

另一方面，现在它仅在TextField聚焦时起作用...
