JTable: colored rows, how to?

[Fabio Luis De Paoli]

I've searched the JTable API and the Java tutorial but I haven't been able
to discover how to change the color of one specific JTable row.

I have an application with a table that lists monetary values and I want to
color with red the rows that have a currency different from the apps'
standard currency.

Another variation that would suit my needs would be to make the row use a
bold or italic font or a different font from the standard JTable font.

Tks, Fabio

You use a JTableRenderer to do that. Here's an example of one that I use:

public class IStringTableRenderer extends BNBTableRenderer implements
TableCellRenderer
{
private IString rendered;

public IStringTableRenderer(IString is) {
rendered = is;
}

public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus,
int row, int col) {
Component renderer = super.getTableCellRendererComponent(table, value,
isSelected, hasFocus, row, col);
if (row != 0 && rendered.isOverridden(row))
renderer.setFont(BNBUtil.boldFont);
else
renderer.setFont(BNBUtil.plainFont);
return renderer;
}
}

To have the JTable use this to render its cells, I just write

theTable.setDefaultRenderer(Object.class, new IStringTableRenderer(is));
