JavaFX相当于java.awt.EventQueue [英] JavaFX equivalent to java.awt.EventQueue

问题描述

JavaFX是否包含与java.awt.EventQueue等效的内容？对于我的应用程序，我需要拦截所有与GUI相关的事件，例如鼠标和键盘输入，到目前为止，我还没有找到一种方法来实现它而不将侦听器连接到每个GUI元素。

Does JavaFX contain an equivalent to java.awt.EventQueue? For my application I need to intercept all GUI related events such as mouse and keyboard input, and so far I haven't been able to find a way to do it without attaching listeners to every GUI element.

推荐答案

这与标题中的问题不完全相同，但是为了拦截所有事件，您可以向场景中添加一个EventFilter：

This isn't quite the same as the question in your title, but to intercept all events, you can add an EventFilter to the Scene:

scene.addEventFilter(Event.ANY, new EventHandler<Event>() {
        @Override
        public void handle(Event event) {
            System.out.println(event);
        }
});

如果您需要否决该事件，请致电 event.consume（）

If you need to veto the event, call event.consume()
