[Java] Class DefaultTableHeaderCellRenderer

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JLabel
                  javax.swing.table.DefaultTableCellRenderer
                      com.wordpress.tipsforjava.swing.table.DefaultTableHeaderCellRenderer

public class DefaultTableHeaderCellRenderer
extends DefaultTableCellRenderer

A default cell renderer for a JTableHeader.

Extends DefaultTableCellRenderer.

DefaultTableHeaderCellRenderer attempts to provide identical behavior to the renderer which the Swing subsystem uses by default, the Sun proprietary class sun.swing.table.DefaultTableCellHeaderRenderer.

To apply any desired customization, DefaultTableHeaderCellRenderer may be suitably extended.

Constructor Detail

DefaultTableHeaderCellRenderer

public DefaultTableHeaderCellRenderer()
Constructs a DefaultTableHeaderCellRenderer.

The horizontal alignment and text position are set as appropriate to a table header cell, and the renderer is set to be non-opaque.

 
Method Detail

getIcon

protected Icon getIcon(JTable table, int column)
Overloaded to return an icon suitable to a sorted column, or null if the column is unsorted.
Parameters:
table - the JTable.
column - the colummn index.
Returns:
the sort icon, or null if the column is unsorted.

getSortKey

protected SortKey getSortKey(JTable table, int column)

getTableCellRendererComponent

@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
Returns the default table header cell renderer.

The icon is set as appropriate for the header cell of a sorted or unsorted column, and the border appropriate to a table header cell is applied.

Subclasses may overide this method to provide custom content or formatting.

Parameters:
table - the JTable.
value - the value to assign to the header cell
isSelected - This parameter is ignored.
hasFocus - This parameter is ignored.
row - This parameter is ignored.
column - the column of the header cell to render
