jcolorchooser - java custom colorChooserPanel -

i want create custom colorchooserpanel jcolorchooser in java swing.

public class colorpanel  extends abstractcolorchooserpanel {      public void buildchooser() {         setlayout(new gridlayout(1, 3));         makeaddbutton("red", color.red);         makeaddbutton("green", color.green);         makeaddbutton("blue", color.blue);  }          public void updatechooser() {         }         public string getdisplayname() {             return "mychooserpanel";  }          public icon getsmalldisplayicon() {             return null;  }          public icon getlargedisplayicon() {             return null;  }          private void makeaddbutton(string name, color color) {             jbutton button = new jbutton(name);             button.setbackground(color);             button.setaction(new abstractaction() {                 private static final long serialversionuid = 1l;                  public void actionperformed(actionevent arg0) {                     jbutton button = (jbutton) arg0.getsource();                     getcolorselectionmodel().setselectedcolor(button.getbackground());              }});             add(button);  } } 

it should show 3 color button instead shows 6 button. may show me did wrong? , how can remove panel below.

colorpanel colorpanel  = new colorpanel(); colorpanel.buildchooser(); colorchooser =  new jcolorchooser(); colorchooser.addchooserpanel(colorpanel);

colorpanel colorpanel  = new colorpanel(); // colorpanel.buildchooser(); <-- remove line 

when add colorpanel jchooserpanel, method called:

public void installchooserpanel(jcolorchooser enclosingchooser) {     if (chooser != null) {         throw new runtimeexception ("this chooser panel installed");     }     chooser = enclosingchooser;     chooser.addpropertychangelistener("enabled", enabledlistener);     setenabled(chooser.isenabled());     buildchooser();     updatechooser(); } 

so don't need "build" panel again since it's built when added colorchooser.
