Javafx 2 单击并双击 [英] Javafx 2 click and double click

问题描述

我想知道是否可以检测到 JavaFX 2 中的双击?以及如何?

I would like to know if it was possible to detect the double-click in JavaFX 2 ? and how ?

我想在单击和双击之间创建不同的事件.

I would like to make different event between a click and a double click.

谢谢

推荐答案

是的，您可以检测单次、双击甚至多次点击:

Yes you can detect single, double even multiple clicks:

myNode.setOnMouseClicked(new EventHandler<MouseEvent>() {
    @Override
    public void handle(MouseEvent mouseEvent) {
        if(mouseEvent.getButton().equals(MouseButton.PRIMARY)){
            if(mouseEvent.getClickCount() == 2){
                System.out.println("Double clicked");
            }
        }
    }
});

MouseButton.PRIMARY 用于判断鼠标左键(常用)是否触发了事件.阅读 getClickCount() 的 api 可以得出结论，除了单次或双次之外，可能还有多个点击计数.但是我发现很难区分单击事件和双击事件.因为双击的第一次点击计数也会上升单个事件.

MouseButton.PRIMARY is used to determine if the left (commonly) mouse button is triggered the event. Read the api of getClickCount() to conclude that there maybe multiple click counts other than single or double. However I find it hard to distinguish between single and double click events. Because the first click count of the double click will rise a single event as well.
