Java MouseListener for ComboBox [英] Java MouseListener for ComboBox

问题描述

如何向 ComboBox 中添加 MouseListener ？我试过：

How do I add a MouseListener to a ComboBox? I have tried:

comboBox.addMouseListener(new MouseAdapter() { 
    public void mousePressed(MouseEvent event) {
        System.out.println("ok");   
    }

    public void mouseReleased(MouseEvent event) {
        System.out.println("ok");   
    }
});

似乎不行。我需要让程序做一些事情，当我按下 ComboBox ，例如，因为它是可编辑的输入。

It doesn't seems to work. I need to make the program do something when I press on the ComboBox, for example for typing because it is editable.

推荐答案

对于基本挥杆相关问题（我假设你在这里使用挥杆），检查 Java教程。

For basic swing related questions (I assume you use swing here), check the swing trail of the Java tutorial.
