How can I write a custom JTable cell renderer which can interpret \n as a newline and display two lines in a cell.
eg: Name: Rhea
Status: Active
Currently using the default cell renderer, If I insert string"Name: Rhea \n Status: Active" it does not print Status: Active on a new line.
Please can anyone share a thought
Thanks,
Rhea
[nobr]You can use html tags within Swing, so I think you can do the following:
/*
* MyRenderer.java
*
* Created on 26 April 2007, 10:27
*
* To change this template, choose Tools | Template Manager
* and open the template in the editor.
*/
package newpackage;
import java.awt.Component;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.SwingConstants;
import javax.swing.table.TableCellRenderer;
/**
*
* @author CS781RJ
*/
public class MyRenderer extends JLabel implements TableCellRenderer
{
public MyRenderer()
{
setHorizontalTextPosition(SwingConstants.RIGHT);
setIconTextGap(3);
setOpaque(true);
}
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean cellHasFocus, int row, int column)
{
if (isSelected)
{
setBackground(table.getSelectionBackground());
setForeground(table.getSelectionForeground());
}
else
{
setBackground(table.getBackground());
setForeground(table.getForeground());
}
if (value instanceof String)
{
if ((value != null) && (value.toString().length() > 0))
{
System.out.println("Value: " + value.toString());
setFont(new java.awt.Font("Tahoma", 0, 11));
setText("<html>" + value.toString().replaceAll("\n", "<br>") + "</html>");
}
}
return this;
}
}
In the class that has the JTable, use the code AFTER declaring the values, columns, etc:
jTable1.getColumnModel().getColumn(0).setCellRenderer(new MyRenderer());
jTable1.setValueAt("Riz\nJavaid", 0, 0);
One thing I haven't done is to resize the cell heights, make sure this is done.
Hope this helps
