Edited 3 Years Ago by Nick Evan: Fixed formatting

You are calling the method wrong. The compiler tells you EXACTLY what is the problem. If you can't figure out such a simple message, what are you doing with GUIs and not learning the basics of java?

proj.java:101:
showDialog(java.awt.Component,java.lang.String,java.awt.Color)
in javax.swing.JColorChooser cannot be applied to
(javax.swing.JPanel,java.lang.String,javax.swing.JColorChooser)

As you can see you are not calling the method with the right arguments.

Check the API: JColorChooser
