通知桌面任务已完成

Question

I'm building a Java application with a Swing GUI and a task that takes a lot of time to complete (from 10secs to 10minutes, don't have any real control on the hamsters).

For now I switch between two JPanel s inside another JPanel which has CardLayout layout manager to say " I'm working " or " I'm done ". The switching between panels doesn't notify the desktop that something has changed.

Is there any way to notify the operating system that the task has completed?

Real world examples: on Windows XP it should make the taskbar button blink, in Mac OSX it should make the dockbar icon jump.

Thanks in advance!

Answer 1

Real world examples: on Windows XP it should make the taskbar button blink, 
in Mac OSX it should make the dockbar icon jump.

Since is possible to notify WindowAdapter , better would be implement todays SystemTray (similair here ), and if Task ended then display Message from status by using TryIcon#displayMessage .

Answer 2

在GUI组件中实现Observer界面，并让您的任务扩展Observable 。

Although the post is a bit old, I guess it should set you on the right track: http://today.java.net/pub/a/today/2003/12/08/swing.html

It explains how to do what you want using JNI and Mac's alternative JDirect.
