Mar 25, 2012 - Why do I keep getting an erro at list.addSelectionListener? I added all the imports, including javax.swing.event.*;

Apr 14, 2012 - Did you typed it correctly - list.addListSelectionListener() ?

CyanGekko Says:

Apr 16, 2012 - It's nice and easy that you can just call in Color.BLACK, etc to make PURE colors (like, in rgb, (0, 0, 0), (255, 255, 255), (255, 0, 0), (0, 255, 0)), but how would you make the background something like (225, 66, 72)?

Mewigi Says:

May 2, 2012 - If you onto the java.awt.Color Javadocs page, you'll see that there is a variety of constructors to use. One of them is "Color(int r, int g, int b)". So you can just use "new Color(225, 66, 72)". Keep in mind that Color is just a class, and the colors like Color.BLACK are just Color objects that you can access.

MrTimoteo1596 Says:

May 9, 2012 - you have to make a color object Color color1=new Color(225,66,72);then when you want to set the background of something you just do .setBackground(color1);

ExemptFrom Says:

May 9, 2012 - or .setBackgound(new Color(225,66,72)); if just using the colour once.

May 28, 2012 - i found a bug if you hold ctrl(control) and click on the same color 2 times or more you get a error
