public class ContactListTreeCellRenderer
extends JPanel
implements TreeCellRenderer, Icon, Skinnable

The ContactListCellRenderer is the custom cell renderer used in the Jitsi's ContactList. It extends JPanel instead of JLabel, which allows adding different buttons and icons to the contact cell. The cell border and background are repainted.
