如何从Java2D生成的图形生成事件 [英] How to generate events from graphics generated by Java2D

问题描述

我已经在java.awt.geom.Ellipse2D的帮助下创建了一个椭圆。

I have made an Ellipse with the help of java.awt.geom.Ellipse2D

现在，只要用户点击该椭圆，就会生成一个事件所以我可以听这个事件，并且基于生成该事件的椭圆来完成后续任务。

Now, I want that whenever user clicks on that ellipse, an event is generated so that I can listen to that event and peform subsequent tasks based on the ellipse which generated that event.

推荐答案

这是一个简单的示例图示对象绘图程序，演示点击，拖动和多重选择。还要考虑 JGraph ，这是一个更高级的图形可视化库。

Here is a simple example of an object drawing program that demonstrates click, drag and multiple selection. Also consider JGraph, which is a much more advanced library for graph visualization.
