how do I change the font of individual combo box items, say if I have 5
items in a combo box , how can I have each of them in a different font ? I
can do combo.setFont(Font f) but is there any way I can set the font of the
combo Items ?

Also,In my combobox  i want to display more than one item of every font type.
I want the source code or logic.

Note:

using list cell renderer it is giving only one item of every font type.But i
want more than one item of every font in one combobox.

This is my code which need changes
