Adding column to JTable with JSlider determined header

**oli_t** · March 6th, 2013, 01:57 PM

Hi,

This is the first time posting, up to now I've managed to use other people's questions to answer any questions I've had, but I have been working on this for two days and have got nowhere.

I am trying to add a column to a JTable with the header specified by a JSlider (PickNumValue) on the click of a button in a different window. The JSlider and button are in the same class and I have a Default Table Model underpinning my JTable. I have put some code below, however have messed around with this all so much that I am sure it is beyond wrong. What I am in need of is some guidance in terms of how best to achieve what I describe.

Advice most greatly appreciated,
Oli

The posted code does not compile without errors. There is No way to test it without a clean compile.

Sorry Norm. I've just tested these two classes and they do now run OK.
Any advice appreciated.

Why does the first class extend JApplet?

How is the program executed? If Data is an applet do you use an HTML page?

The code still has lots of compiler warnings and some errors

Can you make a smaller program that compiles, executes and shows the problem?

This code is very messy and has too many problems.
