Please help - how to set the background color without closing down the JColorChooser box?

i all,

I am a beginner studying Java and have a question about stateChanged method in the JColorChooser class.

The program consists four different areas and if a user rightclick on an area, a color chooser dialog
is then displayed. The background color of current working area should be changed immediately once
a different color is chosen. However, my program does not change the background color without closing down the color
dialog.

I was trying to find the answer on the Internet for 1 day, but could not find the answer.
I would really appreciate if anyone can give me any help on how to solve this problem.

Please see the code below for details.
