Errors caused by classes TablePanel, CellPosition , TextPaintable

**stayfierce** · 12-02-2009, 05:25 PM

I have downloaded this source code from a website. I am trying to simply run this code in NetBeans. When I try to before running the code, there are several errors message regarding the TablePanel, TextPaintable, and CellPosition classes.

As you can see, the code has several imports. However, the classes mentioned above, are still causing errors. This is the complete code for the program, so I am not understanding why I am having errors.

Do I need to import additional classes? Is there another reason why NetBeans not recognizing these classes?

I have attached the exact zip file I downloaded from the website. Please let me know if you can help. Maybe I am missing something.

Here I am encountering problems with the TablePanel class

Those aren't base java classes. If they haven't come with the code you downloaded then I have no idea what package they belong to. It doesn't help that whoever wrote this didn't import specific files, but simply imported whole packages, so you can't even find out which package they were supposed to belong to.
