下面的代码显示两个面板，黄色和蓝色，其中蓝色是黄色的孩子。如何在JavaFX中以编程方式触发鼠标事件？
如果我点击进入蓝色面板的中心，则用两个面板处理鼠标事件。
如何以编程方式模拟相同的行为？
在Fire event按钮我试图做到这一点，但失败：生成的事件似乎只能通过黄色窗格处理。
是否可以发布事件，以便所有孩子都能处理它，就好像它发生在“本地”事件一样？

UPDATE
我不能提子节点明确，因为在一般情况下，它可儿的众多数量。
我怎么知道哪一个目标？
我想传递坐标并让系统自动确定目标。
是不是有点相关[你昨天问过的问题]（http://stackoverflow.com/q/40023260/3429133）？ – beatngu13
