    The posted code does not compile without errors.

    Can you make a small simple complete program that compiles, executes and shows the problem?

    It is missing the Calculator class and ProgressBar class.

    Calculator class:

    package oldschool.runescape.com; import java.awt.EventQueue; import java.awt.ev - Pastebin.com

    ProgressBar class:

    package oldschool.runescape.com; import java.awt.BorderLayout; import java.awt. - Pastebin.com

    None of that has anything to do with using the JTabbedPane. 90% of the posted code is not relevant to the problem.

    The main code I posed is using the JTabbedPane. In method loadClient().

    Ok, copy it to a small testing program that compiles, executes and shows the problem and post that here.

    There's nothing being printed out, I have the code in an Eclipse project. It's just not showing the tabbed pane.

    If you want someone to test the code to help you find the problem:
    write a small, simple complete program that compiles, executes and shows the problem

    The class RS2Loader is the one that compiles and executes fine, you just have to put the classes I gave you into the right packages.

    Sorry, I don't want to work with that huge mess of code that is not part of the problem.
