The tabbed pane is not showing up, what am I doing wrong?

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

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

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

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.
