                                                        java.lang.Object value,
                                                        boolean isSelected,
                                                        boolean hasFocus,
                                                        int row,
                                                        int column)

Returns the component used for drawing the cell. This method is used to configure the renderer appropriately before drawing.

Parameters:

table - the JTable that is asking the renderer to draw; can be null

value - the value of the cell to be rendered. It is up to the specific renderer to interpret and draw the value. For example, if value is the string "true", it could be rendered as a string or it could be rendered as a check box that is checked. null is a valid value

isSelected - true if the cell is to be rendered with the selection highlighted; otherwise false

hasFocus - if true, render cell appropriately. For example, put a special border on the cell, if the cell can be edited, render in the color used to indicate editing

row - the row index of the cell being drawn. When drawing the header, the value of row is -1

column - the column index of the cell being drawn
