hi,
I use jdbtable to view data,I want them to chang row color when some cells equal the value.But interface getTableCellRendererComponent not run.I don't know why!
jdbtable is extend jtable ,it made in borland jbuilder.
//1 class
package errorreport;
import java.awt.Component;
import java.awt.Color;
import javax.swing.table.DefaultTableCellRenderer;
import com.borland.dbswing.*;
public class rowcolor extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent
(JdbTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column)
Component cell = super.getTableCellRendererComponent
(table, value, isSelected, hasFocus, row, column);
int iColcount = 0;
iColcount = table.getColumnCount();
if( value instanceof String )
String strAlmlev = (String)value;
if(strAlmlev.trim().equals("C1"))
cell.setBackground( Color.red );
// You can also customize the Font and Foreground this way
// cell.setForeground();
// cell.setFont();
else
if(strAlmlev.trim().equals("C2"))
cell.setBackground( Color.orange );
else
if(strAlmlev.trim().equals("C3"))
cell.setBackground( Color.yellow );
else
if(strAlmlev.trim().equals("ERR"))
cell.setBackground( Color.green );
return cell;
//2 class
JdbTable jdbTable2 = new JdbTable();
TableCellRenderer renderer = new rowcolor();
try
jdbTable2.setDefaultRenderer( Class.forName( "java.lang.String" ), renderer );
catch( ClassNotFoundException ex )
System.exit( 0 );
thanks
