Setting foreground of a table cell on date column

[Jennifer Sohl]

How do I set the foreground of a cell that is
of the date column class in my renderer?
I've tried

if(value.toString().equals("Jan 1, 1900")
  setForeground(Color.white);
}

But it doesn't seem to work.
Something else interesting...
I tried doing the following:

if( value instanceof Date) {
     System.out.println("Date value");
} 

and nothing ever prints to std out. Any ideas why??
What am I missing?
Thanks!

How are you setting this renderer on your table?

[Jennifer Sohl]

I am using the following:

myTable.setDefaultRenderer(Object.class, new MyRenderer());
 

[Jennifer Sohl]

I just tried something else in my renderer:
I added the following code:

if(column == 9) // This is a date column
  System.out.println("Column 9");
}

Nothing ever printed out, like the column wasn't ever equal to index 9???
The same thing happens on columns of Integer type.
If the column is a String , it prints out.
Here's my model:

public class GeneralModel extends AbstractTableModel {
private int columns = 13;
private String columnNames[] = {" \nORDER"," \nCODE","CUST\nCODE"," \nNAME"," \nCITY"," \nSTATE"," \nDESCRIPTION","ORD\nTYPE","SCHED\nSHIP","ACTUAL\nSHIP"," \nSTATUS","OPER\nDIV","MRKT\nUNIT",};
private Vector dataRows;
private ArrayList toolTips;
//----------------------------------------------------
public void setGeneralData(ResultSet data) throws Exception {
// Get all rows.
dataRows = new Vector();
Object[] rowData;
toolTips = new ArrayList();
try {
while(data.next()) {
toolTips.add(data.getString(14));
rowData = new Object[columns];
/**
*  Populate each column with the proper data
*/
for(int j=0; j < columns;j++) {
switch (j) {
// Order number
case 0:
rowData[j] = new Integer(data.getInt(1));
break;
// Order code
case 1:
rowData[j] = "  " + data.getString(2);
break;
// Customer Code
case 2:
rowData[j] = data.getString(3);
break;
// Name
case 3:
rowData[j] = data.getString(4);
break;
// City
case 4:
rowData[j] = data.getString(5);
break;
// State
case 5:
rowData[j] = data.getString(6);
break;
// Order Description
case 6:
rowData[j] = data.getString(9);
break;
// Order Type
case 7:
rowData[j] = data.getString(10);
break;
// Scheduled Ship
case 8:
rowData[j] = (java.util.Date)data.getDate(11);
break;
// Actual Ship
case 9:
rowData[j] = (java.util.Date)data.getDate(12);
break;
// Hold cancel flag
case 10:
if(data.getString(13).equals("C")) {
rowData[j] = "Cancelled";
}
else if (data.getString(13).equals("H")) {
rowData[j] = "On Hold";
}
else {
rowData[j] = "";
}
break;
// Operating Division
case 11:
rowData[j] = data.getString(7);
break;
// Marketing Unit
case 12:
rowData[j] = data.getString(8);
break;
}
}
dataRows.addElement(rowData);
}
fireTableChanged(null);
}
catch(SQLException sqle) {
throw sqle;
}
}
//-----------End of setGeneralData() method-------------------------
public int getColumnCount() {
return columnNames.length;
}
public int getRowCount() {
if(dataRows == null) {
return 0;
}
else {
return dataRows.size();
}
}
public Object getValueAt(int row, int column) {
return ((Object[])(dataRows.elementAt(row)))[column];
}
public String getColumnName(int column) {
return columnNames[column] == null ? "No Name" : columnNames[column];
}
public void setColumnName(int column,String name) {
columnNames[column] = name;
}
public Class getColumnClass(int column) {
return getValueAt(0,column).getClass();
}
        public ArrayList getToolTips() { 
                         return toolTips;
        }
}  

Here's my renderer:

public class GeneralRenderer extends DefaultTableCellRenderer {
private Font p = new Font("SansSerif", Font.PLAIN,12);
private Font hl = new Font("SansSerif",Font.ITALIC+Font.BOLD,12);
private Font hl2 = new Font("SansSerif",Font.BOLD,12);
private Color orange = new Color(255,115,0);
private JLabel label;
private ArrayList toolTips;
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {

Component cell = super.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);

if(value != null) {
if(value.toString().trim().equals("Cancelled") || value.toString().trim().equals("Backordered")) {
cell.setFont(hl);
cell.setForeground(Color.red);
}
else if(value.toString().trim().equals("On Hold")) {
cell.setFont(hl);
cell.setForeground(orange);
}
// All other cells
else {
cell.setFont(p);
cell.setForeground(Color.black);
}
}
// Align columns.
if(column == 2 || column == 5 || column == 7 || column == 11 || column == 12) {
label = (JLabel)cell;
label.setHorizontalAlignment(SwingConstants.CENTER);
}
else if (column == 0) {
label = (JLabel)cell;
label.setHorizontalAlignment(SwingConstants.RIGHT);
}
else {
label = (JLabel)cell;
label.setHorizontalAlignment(SwingConstants.LEFT);
}
// Set Tool Tip Text for order number column and description column
if(column == 6) {
JComponent c = (JComponent)cell;
c.setToolTipText(value.toString());
}
else if(column == 7) {
JComponent c = (JComponent)cell;
c.setToolTipText((String)toolTips.get(row));
}
else {
JComponent c = (JComponent)cell;
c.setToolTipText("");
}
}
public void setToolTips(ArrayList tips) {
toolTips = tips;
}
}

Here is how I am setting the renderer:

model = new GeneralModel();
renderer = new GeneralRenderer();
gSorter = new TableSorter(model);
gTable = new JTable(gSorter);
gTable.setDefaultRenderer(Object.class,renderer);
gTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
gTable.setShowGrid(false);
gTable.setRowHeight(30);
gSorter.addMouseListenerToHeaderInTable(gTable);
gTable.setRowHeight(23);
mlhr = new MultiLineHeaderRenderer();
setColumnHeaders();

What's going on???
Many thanks to anyone that can help!

Try with this code
public class GeneralRenderer extends DefaultTableCellRenderer
{
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row, int column)
{
if(column == <Date Column No>
{
setFont(<font> ;
setBackground(<BackgroundColor> ;
setForeground(<ForegroundColor> ;
}
return this;
}
}

JTables use the most specific renderer they can... they already have a default renderer for String, Integer, Boolean, etc. so they are never going to use your renderer if you register it with the java.lang.Object class. You're going to have to set your renderer as the default renderer for the String.class, the java.util.Date.class, and anything else your renderer is providing a view for.

[Jennifer Sohl]

Thanks for all the help. I tried setting the default renderer for each class String, Integer and Date, and it is working now.
Funny, I've never run into that before.
Guess you learn something new every day!!
Thanks again!
