使用ActionListener与MouseListener捕获JButton点击的优缺点 [英] Pros and cons of using ActionListener vs. MouseListener for capturing clicks on a JButton

问题描述

我有一个JButton，并希望捕获鼠标点击它。使用ActionListener与在JButton上使用MouseListener之间有什么实际和哲学上的区别？

I have a JButton, and would like to capture mouse clicks on it. What are the practical and philosophical differences between using an ActionListener vs. using a MouseListener on the JButton ?

推荐答案

ActionListener用于处理按钮的逻辑单击。点击发生

An ActionListener is used to handle the logical click of a button. A click happens

• 当按下鼠标然后在按钮上释放时，


• 或当使用该按钮的键盘快捷键，


• 或当按钮具有焦点并按下空格键时，


• 或当按钮是默认按钮和Enter按下，


• 或以编程方式调用按钮的click（）方法

• when the mouse is pressed then released on a button,
• or when the keyboard shortcut of that button is used,
• or when the button has the focus and the space bar is pressed,
• or when the button is the default button and Enter is pressed,
• or when the button's click() method is called programmatically

MouseListener只处理低级鼠标事件。

A MouseListener only handles low-level mouse events.
