java - 为辅助鼠标按钮添加鼠标事件 Javafx

Question

所以我有这个锚定 Pane ，我想在其中为辅助鼠标键添加鼠标监听器我尝试了以下但我不断收到错误有人知道问题出在哪里吗？

   mainDisplayPanel.addEventHandler(MouseButton.SECONDARY, new EventHandler<MouseButton>() {

                    @Override
                    public void handle(MouseButton event) {
                        System.out.Println("Works");

                    }
                });

郑重声明，我也试过这个:

            mainDisplayPanel.addEventHandler(MouseButton.SECONDARY, new EventHandler<MouseEvent>() {

                @Override
                public void handle(MouseEvent event) {
                    System.out.println("WOrks");
                }
            });

堆栈跟踪:

Bound mismatch: The generic method addEventHandler(EventType, EventHandler) of type Node is not applicable for the arguments (MouseButton, new EventHandler(){}). The inferred type MouseButton&Event is not a valid substitute for the bounded parameter

还有一个:

Bound mismatch: The type MouseButton is not a valid substitute for the bounded parameter of the type EventHandler

Answer 1

没有基于MouseButton.SECONDARY 的EventType。您需要检查 MouseEvent 本身:

mainDisplayPanel.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>() {

    @Override
    public void handle(MouseEvent event) {
        if (event.getButton() == MouseButton.SECONDARY) {
           System.out.println("Works");
        }
    }
});
