如何用Java以编程方式将MouseEvent激活到MouseListener？ [英] How to programmatically fire a MouseEvent to a MouseListener with Java?

问题描述

我有一个 JTree ，带有自定义关联的 MouseListener （用于显示弹出窗口等）。我需要触发一个 MouseEvent ，它将被 MouseListener 捕获。我应该如何以编程方式执行此操作？

解决方案

您可以创建自己的MouseEvent并循环遍历所有侦听器并进行调用。 / p>

例如：

  MouseEvent me = new MouseEvent（tree，0 ，0,0,100,100,1，false）; 
 for（MouseListener ml：tree.getMouseListeners（））{
 ml.mousePressed（me）; 
} 
  

I have a JTree with a custom associated MouseListener (for showing popup etc.). I need to fire a MouseEvent that will be caught by the MouseListener. How should I do that programmatically?

解决方案

You could create your own MouseEvent and loop through all the listeners and make the call.

For example:

MouseEvent me = new MouseEvent(tree, 0, 0, 0, 100, 100, 1, false);
for(MouseListener ml: tree.getMouseListeners()){
    ml.mousePressed(me);
}
