JScrollPane 在行标题上显示图形故障。如何避免这种情况？
我正在尝试使用带有列标题和行标题的 JScrollPane 。
行标题上有一些文本。当我向下滚动窗格时，行标题上会出现一些图形伪影。就好像像素的底线一次又一次地重复。
如果我最大化并恢复主窗口，问题就解决了，但这不是应该的方式。
有什么办法可以避免这种情况吗？
I'm trying to use a JScrollPane with a column header and a row header.
On the rowheader, there is some text. When I scroll down the pane, some graphics artifacts appear on the rowheader. It's like the bottom line of pixels is repeated once and again.
The problem is solved if I maximize and restore the main window, but it's not the way it should be.
Is there any way to avoid this?

我发现像这样的故障通常是由自定义
paint()方法或更改后未重新绘制引起的。首先，我总是在自定义绘制方法中作为第一行进行调用。
我还发现这两行让一切保持新鲜和最新。他们可能很耗时，但解决了很多问题。我通常将它们放在修改视图的代码末尾。
I find that glitches like this are usually caused by custom
paint()methods or not repainting after you make changes.First, I always call as the first line in my custom paint method.
I also find that these two lines keep everything fresh and up to date. They might be time consuming, but they have solved a lot of problems. I usually put them at the end of code that modifies the view.
