在空JTextField中按下退格键时禁用蜂鸣声 [英] Disable beep when backspace is pressed in an empty JTextField

问题描述

初学者。当按下退格并且字段为空时，是否有人知道一种快速简便的方法让JTextField不发出蜂鸣声？我在网上看到了一些关于更改DefaultEditorKit的事情，但我没有能够理解。任何帮助将不胜感激。

Beginner here. Does anybody know a quick and easy way to get a JTextField to not beep when backspace is pressed and the field is empty? I've seen a couple things online about changing the DefaultEditorKit, but nothing I was able to make sense of. Any help would be greatly appreciated.

推荐答案

此代码适用于我。

Action beep = textArea.getActionMap().get(DefaultEditorKit.deletePrevCharAction);
beep.setEnabled(false);
