| Returns the component used for drawing the cell. This method is
used to configure the renderer appropriately before drawing.
The TableCellRenderer is also responsible for rendering the
the cell representing the table's current DnD drop location if
it has one. If this renderer cares about rendering
the DnD drop location, it should query the table directly to
see if the given row and column represent the drop location:
JTable.DropLocation dropLocation = table.getDropLocation();
if (dropLocation != null
&& !dropLocation.isInsertRow()
&& !dropLocation.isInsertColumn()
&& dropLocation.getRow() == row
&& dropLocation.getColumn() == column) {
// this cell represents the current drop location
// so render it specially, perhaps with a different color
}
During a printing operation, this method will be called with
isSelected and hasFocus values of
false to prevent selection and focus from appearing
in the printed output. To do other customization based on whether
or not the table is being printed, check the return value from
javax.swing.JComponent.isPaintingForPrint .
Parameters:
table - the JTable that is asking the renderer to draw; can be null
Parameters:
value - the value of the cell to be rendered. It isup to the specific renderer to interpretand draw the value. For example, ifvalueis the string "true", it could be rendered as astring or it could be rendered as a checkbox that is checked. null is avalid value
Parameters:
isSelected - true if the cell is to be rendered with theselection highlighted; otherwise false
Parameters:
hasFocus - if true, render cell appropriately. Forexample, put a special border on the cell, ifthe cell can be edited, render in the color usedto indicate editing
Parameters:
row - the row index of the cell being drawn. Whendrawing the header, the value ofrow is -1
Parameters:
column - the column index of the cell being drawn
