Zoom geometry using JSlider

Hi,

I want to design a JSlider to zoom in or out polygons.What I expected is the old drawing would be replaced the new drawing.
Actually I use repaint() method, however I found the screen was mess up.
The new and old pictures coexisted when I fired the event.

What is the reason it could be?
I am sorry my code is too complex to make it as an example.

Thanks

guess: you're not using getValueIsAdjusting(), but guesses rarely solve problems,
so here's a basic program - add your code to reproduce the problem,
then post back so we can see what you're doing.

 
It is sorta covered in the JavaRanch Style Guide.
