Swing：多面板显示和突出显示文本的对象

Question

I plan on making a multi comparison program. It will compare multiple files by displaying N number of files in a grid where N = X * Y. X and Y are the width and height of the grid elements. Easy enough, I know how to do this pretty much.

The question: How do and in what way is best to highlight individual characters in each of these grid elements? I plan on highlighting matching text that is found in the same position.

Answer 1

You could use a JTextArea with a Highlighter . See the second example on this page for how.

Answer 2

I'd use a JTextPane rather than a JTextArea, and read up on the StyledDocument class. This will give you all sorts of options.

Answer 3

我不确定“突出显示字符”是什么意思，但是要引起人们对网格元素或网格元素对的关注，可以设置适当组件的背景色。
