Java Swing GUI 沙漏 [英] Java Swing GUI hour glass

问题描述

在我的 Swing 程序中有一个 JTabbedPane.当用户点击选项卡时，程序需要一段时间来获取数据并处理结果，然后在所选选项卡中显示结果.

There is a JTabbedPane In my Swing program. When user clicks on a tab, the program takes a while to get the data and process the results, then shows the results in the selected tab.

如何显示沙漏或类似效果，以便用户知道它正在处理数据?在完成工作之前不要再次单击该选项卡.

How can I display a hour glass, or something of that effect so that user knows it's processing data? Not to click on the tab again before it finishes it job.

推荐答案

A JProgressBar(可能处于不确定模式)听起来不错 - 将其放在选项卡上，直到获取数据.设计良好的 UI 不应强迫用户等待长时间运行的任务完成，而应允许他们在中间做其他事情.

A JProgressBar (possibly in indetermiante mode) sounds right - put that on the tab until the data has been fetched. A well-designed UI shouldn't force the user to wait for long-running tasks to complete and instead allow them to do something else inbetween.
