当我将鼠标移到组合框上的单元格上时，我正在尝试更改颜色。我是使用鼠标事件还是仅此单元格渲染器？
我用什么方法改变颜色 JComboBox 鼠标悬停？
这是我的密码：

jComboBox2.setRenderer(new DefaultListCellRenderer() {
    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(new Color(242,242,242));
        }
        if(index == 0){
            c.setForeground(new Color(242,242,242));
            c.setBackground(new Color(26,35,48));
        }
        if(index == 1){
            c.setForeground(new Color(101,150,226));
            c.setBackground(new Color(26,35,48));
        }
        if(index == 2){
            c.setForeground(new Color(77,105,205));
            c.setBackground(new Color(26,35,48));
        }
        if(index == 3){
            c.setForeground(new Color(137,71,255));
            c.setBackground(new Color(26,35,48));
        }
        if(index == 4){
            c.setForeground(new Color(212,43,230));
            c.setBackground(new Color(26,35,48));
        }
        if(index == 5){
            c.setForeground(new Color(235,75,75));
            c.setBackground(new Color(26,35,48));
        }
        else {

        }
        return c;
    }
});
