在getListCellRendererComponent中双击时更改颜色

Question

How can I change color when I double click the cell of JList ? Is there a way adding a MouseListener within DefaultListCellRenderer ?

public class Renderer extends DefaultListCellRenderer{

 @Override
    public Component getListCellRendererComponent(JList list, Object value, int index,boolean isSelected, boolean cellHasFocus) 
    {
        Component c = super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);
        if(isSelected){
            c.setBackground(Color.ORANGE);
            c.setForeground(Color.BLACK);
        }
        return c;
    }
}

I has a similar situation recently where I wanted to double click table entries and have them added in a list. The trick was to:

• Add a boolean in the table to denote 'has been added to list'.
• On double click (add the row to list &) set that value to true.
• When rendering, check the boolean and decide how to render it.
