2D graphic repaint() logic

[Keith Gerrard]

HI i have a problem with my program.
I need to pass the value from the textfield which is from the ValueInput.java to reflect into the tabbedpane of my LineGraph.java which i think is to repaint() as the LineGraph.java contain a graphic g component.
But I failed to do that.
The value of the LineGraph is predefine in the PMGraph2.java.

please advice on how to pass or parse the value to the LineGraph.java
if need the file.zip
pls Advice...Urgent

This is probably better asked in our Other Java APIS forum, so I'm moving it there.
