hey everyone, I am using a custom TableCellRenderer to render a column in a JTable. This works great BUT when I select a column in the table, the column that is using the renderer is not highlighted. My custom renderer is pasted below. Does anyone know how I can highlight the JLabel if isSelected is true? Thanks.
class MyTableCellRenderer extends JLabel implements TableCellRenderer {
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int rowIndex, int vColIndex) {
setText(value.toString());
// more stuff here
return this;
}
}

You need to use the isSelected boolean the the method signiture and set the background you self...

if you are using j2se 1.4 or might ever going to use it, you should extend the DefaultTableCellRenderer not just implement the interface. this makes a big performance difference. see the API of DefaultTableCellRenderer and the source code (1.4!) for more information. moreover, inheritance might spare you some code concerning the selection problem.
cheers
