Java：彻底禁用任何Swing不必要的哔声的方法？ [英] Java: way to completely disable any Swing unwanted beeps?

问题描述

我正在使用Swing开发一个相当复杂的Java应用程序。

I am working on a fairly complex Java application using Swing.

在某些情况下，如果没有任何用户干预，会发出不必要的蜂鸣声。没有崩溃，应用程序保持正常工作，我尊重EDT规则等。

On some occasions there are unwanted beeps without any user intervention. No crash, application keeps working fine, I'm respecting the EDT rules etc.

然而在某些情况下可以听到一声嘟嘟声：我可能正在做一些愚蠢的事情触发发出嘟嘟声，但无论如何，当用户离开时，导入数据时不会发生用户操作。

Yet in some cases a beep can be heard: I may be doing something silly triggering that beep but in any case it s not a user action for it can happen upon importing data, when the user is away.

对于Java应用程序应该是否可行从来没有发出任何声音来配置它，比如为整个应用程序设置一个属性，说：不要发出一声嘟嘟声？

Is it possible, for a Java application that should never ever emit any sound to configure it, say by setting a property for the whole application that says: "dont' ever emit a beep"?

我一直在谷歌搜索那个问题，我发现有相同问题但没有答案的人发来的消息：我发现有一些黑客说有一个已知的问题，JEditorPane和使用 putProperty（IgnoreCharsetDirective，布尔。 TRUE）有助于减少不必要的哔哔声。然而，关于这个问题的信息非常稀少。

I ve been Googling for that issue and I ve found message by people having the same issue but no answer: all I found was some hack saying that there was a known issue with JEditorPane and that using a putProperty("IgnoreCharsetDirective", Boolean.TRUE) was helpful to make unwanted beeps happen less often. Yet information is very scarce on the subject.

这是一个真正的问题，因为应用程序是在计算机上需要声音的环境中使用的，但是这个Java应用程序发出的噪音是不可接受的。

It s a real issue because the application is used in an environment where the sound is needed on the computer, but this Java application emitting noise is unacceptable.

推荐答案

您的问题在Java论坛上讨论过：

Your problem is discussed on the Java Forum:

// Write a custom toolkit
public class MyToolkit extends sun.awt.windows.WToolkit 
{
  public void beep() {
  }
}

// Set this property
System.setProperty("awt.toolkit", "MyPackage.MyToolkit");

注意：使用此解决方法是泄气。你仍然应该尝试找到问题的根源。

NOTE: The use of this workaround is discouraged. You should still try to find the root of the problem.
