将加载圈添加到JTable [英] Add loading circle to JTable

问题描述

我有一个从数据库加载数据的JTable。因为有时数据太多，我想在Jtable中添加一个加载圈来通知用户数据正在加载。这是我希望如何的图像：

I have a JTable that loads data from a database. Because sometimes there's too much data, I would like to add a loading circle inside the Jtable to notify the user that the data is being loaded. Here is an image of how I would like it to be:

这可能吗？如何在Swing中完成？

Is this possible? How can it be done in Swing?

PS：我不想使用进度条，我只想要表格中的圆圈。

PS: I don't want to use the progress bar, I just want the circle inside the table.

更新：该表是GUI的一部分，我只想禁用或显示JTable中的加载，并保持其他组件不变。

UPDATE: The table is part of the GUI and I only want to disable or show the loading inside the JTable and leave the other components intact.

如果你的 SQL解释器支持分页，然后拆分 SQL ResultSet （5 - 20件）并使用 JProgressBar 而不是循环图像，

if your SQL interpreter supports Paginations, then split SQL ResultSet (5 - 20 pieces) and use JProgressBar rather than cycled Images,
