TableCellRenderer Problem

[mbaranski]

I have a table cell renderer class, that should color certian cells of a table and leave others the default. The problem is, all the cells take the properties of the last one I set! The text is correct in each of them, but if I set them all blue except the last one, they are all the color of the last one. Here is some of the code. Thanks for any help.

JTable jt = new JTable....

jt.setDefaultRenderer(Class.forName("java.lang.Object&quot, (TableCellRenderer)jt.getModel());

This is the renderer.

public class InstrumentTableModel extends AbstractTableModel implements TableCellRenderer

public Component getTableCellRendererComponent(
JTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column)
{
if(value != null)
{
j = new JLabel(value.toString());
}
else
{
j = new JLabel(""
value = "";
}

j.setOpaque(true);
j.setBackground(Color.getColor(((InstrumentTableModel)table.getModel()).getHighlightedColor(value.toString())));

j.setForeground(Color.getColor(((InstrumentTableModel)table.getModel()).getHighlightedColor(value.toString())));

return j;
}

Oh yes, the "good" old TableCellRenderer.
I don't know the exact solution, but i'm quite sure, that you need only one component (e.g. your JLabel) globally that is used by each cell.
As i said, i'm not sure, the TreeCellRenderer works this weird way, i guess the TableCellRenderer is similar.
Hope this helps as i have done a TreeCellRenderer 9 months ago...

Making the JLabel global and setting the properties does not help. Does anyone know what the actual problem/solution is?
