JTabbedPane: show task progress in a tab

由 感情迁移 提交于 2019-11-27 02:07:11
I have a simple Swing Java application that performs searches, and the results are shown in a new tab. While the search is running, I want to show a progress icon or animation in the title of the tab. I tried adding a gif icon, but it doesn't animate. Is there a reason why this isn't working? Robin The Swing tutorial about progress bars (and showing progress in general) is a very good place to start. It shows you how to perform long-lasting operations on a worker thread by using a SwingWorker , and updating your UI at certain intervals to show progress of the long-lasting operation to the user
