JEdi​​torPane-制作制表符空间

Question

I'm wondering if there's a way to have tabs convert to spaces in a jeditorpane, much like you'd see when working in an IDE. I don't want to set the tab size . I can already do that easily.

I want to have tabs replaced with their equivalent in spaces. So for example if my tabs are 5 spaces long, I would want all tabs replaced immediately with 5 spaces whenever they are created.

Any ideas?

Add a DocumentFilter to the Document to replaces tabs with spaces as text is inserted into the Document. Read the section from the Swing tutorial on Text Component Features for more information.
