A renderer for list or table cells. Can use text, colour, image, symbol. Expects to use a TwoField, ThreeField or FourField object to obtain up to four values, which are represented using text, colour, an image and a symbol.
The IXRenderer is created with a boolean argument which determines whether the cell has a border or not. The border is used to show whether the cell/row is selected or not.
The fields unselectedBorder, selectedBorder, and isBordered are used to handle the borders of the cell if it has one. The class sub-classes RendererJLabel rather than JLabel for performance reasons (see Java API documentation of TableCellRenderer or ListCellRenderer for more detail).
