I tried to wrote custom renderer, but fail to activate it's features:
public class HeaderRenderer extends JPanel implements TableCellRenderer {
private static final long serialVersionUID = -1247350397731719795L;
@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
int modelColumn = table.convertColumnIndexToModel(column);
/*
if( table.getSelectedColumn() == modelColumn ) {
isSelected = true;
}
*/
JComponent ans;
if (modelColumn == 0) {
ans = new JLabel("<html><pre>" + getColumnName(column) + "</pre></html>");
}
else {
ans = new JLabel("<html><pre>" + String.valueOf(directory.getCorpus(modelColumn - 1)) + "</pre></html>");
table.getColumnModel().getColumn(table.convertColumnIndexToView(column)).setPreferredWidth(300);
}
//ans.setBorder(BorderFactory.createLineBorder(Color.black));
((JLabel) ans).setFont(new Font("SansSerif", Font.PLAIN, 10));
ans.setForeground(Color.BLUE);
//((JLabel)ans).setBackground(Color.yellow);
//ans.setBorder(BorderFactory.createEtchedBorder());
ans.setBorder(BorderFactory.createLineBorder(Color.black));
if (isSelected) {
ans.setBackground(UIManager.getColor("Table.selectionBackground"));
}
else {
ans.setBackground(getBackground());
}
((JLabel) ans).setVerticalAlignment(SwingConstants.TOP);
JTableHeader header = table.getTableHeader();
Dimension dim = new Dimension();
if (ans.getPreferredSize().height > dim.height) {
dim.height = ans.getPreferredSize().height;
header.setPreferredSize(dim);
}
return ans;
}
}
Apparently, header is not repainted upon cell selection, so renderer is not run.
How to force it to run?
