Logging Tab

[Patrick Brahami]

Alright I have finally finished my application business logic and GUI(Swing if it matters).
(a lot thanks to you Java Ranch community!!)

I want to create a new tab that only I (the program) will be able to write to, and it will be just a white text field with messages. And I'll even let the user ability to save it as text file.

Again, I've got naive solutions in my head. But I prefer to advice before
starting so the idea is - how is it done?
Should I work with a label? a big text box?
How can I write line at a time? and is there a limit on the size of lines that can be written to a textbox?

Thanks in advance.

For multiple lines use a JTextArea and set editable to false for other users.

I see. Fits nice.
How can I append text in different color/font size?

Check out JTextPane and StyledDocument.
