how set comboboximage background of mycombobox combobox?

you can set custom renderer combo box using:

mycombobox.setrenderer(...);

a possible implementation of renderer be:

class backgroundrenderer extends jlabel implements listcellrenderer<string> {     private final image image;      public backgroundrenderer(image image) {         this.image = image;     }      @override     protected void paintcomponent(graphics g) {         g.drawimage(image, 0, 0, this);          super.paintcomponent(g);     }      @override     public component getlistcellrenderercomponent(jlist<? extends string> list, string value, int index,             boolean isselected, boolean cellhasfocus) {         settext(value);          return this;     } }
