Using a JCheckBox in the header of a JTable

Question

I would like to know if it is possible to put a JCheckBox in the header of a column of a JTable.
In fact my table has several columns and its first column uses checkboxes to signify the seleced items in the table. I would like to have a checkbox in the header of this column so when it is checked, I select all possible items from the table (not all rows are selectable).
I have not seen any eample of putting something other than text in table headers. Does anyone know if this is possible and how to do it?

Answer 1

I haven't tried check boxes but I use my own header renderers for other purposes. They are the same as cell renderers, so this sort of thing should work...
TableColumn tc = myTable.getColumnModel().getColumn(0);
tc.setHeaderRenderer(new CheckHeaderRenderer());
class CheckHeaderRenderer extends JCheckBox implements TableCellRenderer
  public Component getTableCellRendererComponent(JTable table,
                                           Object  value,
                                           boolean isSelected,
                                           boolean hasFocus,
                                           int     row,
                                           int     column)
    // whatever
    return this;
