title: JComboBox custom ListCellRenderer
body: <p>I've a problem with JComboBox custom ListCellRenderer. I want to create a combobox that let choose between 4 colors. I want the combobox shows the color by a "list" of JPanel with desired color a background. I manage to obtain quite what I want, the only problem is that when I click on item, this change color to grey not displaying anymore the original color.
  Here the code:</p>
  
  <pre><code>package custom_renderer_combobox;
  
  import java.awt.Color;
  import java.awt.Component;
  import java.awt.Dimension;
  
  import javax.swing.JFrame;
  import javax.swing.JList;
  import javax.swing.JPanel;
  import javax.swing.ListCellRenderer;
  import javax.swing.JComboBox;
  
  public class gui extends JFrame{
  
      /**
       * 
       */
      private static final long serialVersionUID = 1L;
  
      private Color[] colors={Color.BLACK,Color.blue,Color.cyan,Color.GRAY,Color.green,Color.MAGENTA,Color.ORANGE,Color.RED};
      gui(){
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setVisible(true);
          setSize(new Dimension(400,400));
          getContentPane().setLayout(null);
  
          JComboBox&lt;JPanel&gt; comboBox = new JComboBox&lt;JPanel&gt;();
          comboBox.setRenderer(new myRenderer());
          comboBox.setBounds(36, 59, 211, 20);
          getContentPane().add(comboBox);
          for(int i=0;i&lt;colors.length;i++){
              JPanel temp=new JPanel();
              temp.setOpaque(true);
              temp.setBackground(colors[i]);
              comboBox.addItem(temp);
          }
          comboBox.repaint();
      }
  
      class myRenderer implements ListCellRenderer{
  
  
          @Override
          public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
              return ((JPanel) value);
          }
  
      }
  }
