如何让我的应用程序图标在Mac Dock中弹跳 [英] How to make my app icon bounce in the Mac dock

问题描述

我正在用Java编写一个IRC客户端，我想知道是否有办法让我的应用程序的图标在触发nickalert（或任何其他相关通知）时在Dock中反弹。

Well I'm writing an IRC client in Java and I was wondering if there was a way to make my app's icon bounce in the dock when a nickalert is triggered (or any other relevant notification).

如果Windows也有某种通知系统，我也想知道它。

If Windows also has some sort of notification system I'd like to know about it as well.

推荐答案

在MacOS下，尝试使用 Application＃requestUserAttention（boolean）

Under the MacOS, try using something like Application#requestUserAttention(boolean)

import com.apple.eawt.Application;
...
Application application = Application.getApplication();
application.requestUserAttention(false);

nb-我没有试过这个我自己的抱歉。

nb- I've not tried this my self - sorry.

更新了示例

来自 JavaDocs

请求用户注意此应用程序（通常通过弹跳
Dock图标）。关键请求将继续反弹Dock
图标，直到应用程序被激活。已经激活的应用程序
请求注意什么都不做。

Requests user attention to this application (usually through bouncing the Dock icon). Critical requests will continue to bounce the Dock icon until the app is activated. An already active application requesting attention does nothing.

这意味着，如果应用程序具有焦点，那么方法将什么都不做。

That means, that if the application has focus, then the method will do nothing.

Ps确保你做对焦应用;）

Ps make sure that you do-focus application ;)
