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

You could create your own MouseEvent and loop through all the listeners and make the call.
您可以创建自己的 MouseEvent 并遍历所有侦听器并进行调用。
For example:
例如：
MouseEvent me = new MouseEvent(tree, 0, 0, 0, 100, 100, 1, false);
for(MouseListener ml: tree.getMouseListeners()){
ml.mousePressed(me);
}

The Robotclass might be what you're looking for.
该机器人类可能是你在找什么。
This class is used to generate native system input events for the purposes of test automation, self-running demos, and other applications where control of the mouse and keyboard is needed. The primary purpose of Robot is to facilitate automated testing of Java platform implementations.
此类用于生成本地系统输入事件，以用于测试自动化、自运行演示以及需要控制鼠标和键盘的其他应用程序。Robot 的主要目的是促进 Java 平台实现的自动化测试。
