checkbox in jtable cell

[dogbody]

Hi,

I'm trying to get a jtable with two columns in it. The first column is just boolean values which I'd like to display as checkboxes and the second column contains strings (representing table names that the user can select using the checkbox).

So far I have managed to get the table populated with the data, but I don't know how to render the cells in the first column to be checkboxes.

I also need to get the values (from the 2nd column) of all the selected items.

note that there's also a combo box being populated with the same data here as well.

	private void populateTables() {
	    
	    cmbStagingTable.removeAllItems();
	    
	    DefaultTableModel model  = new DefaultTableModel();
	    model.addColumn("Include");
	    model.addColumn("Table");
	    
 	    List tables = core.dt.getAllTables(core.dbInfo);
	    for (int x = 0; x < tables.size(); x++) {
	        cmbStagingTable.addItem(tables.get(x));
 
	        Vector row = new Vector();
	        row.add(Integer.toString(0));
	        row.add(tables.get(x));
	        model.addRow(row);
	        
	    }
 
	    tblDestTables.setModel(model);
}

..just using the JTable default behaviour, the clue is to override the

public Class getColumnClass(int column) method.

class ATableClass extends JTable {
  public Class getColumnClass(int column) {
    try {
      if (column == 0) {
        return Class.forName("java.lang.Boolean");
      }
      return Class.forName("java.lang.Object");
    }
    catch (ClassNotFoundException ex) {
      ex.printStackTrace();
      return null;
    }
  }
}
public class TableExample1 extends JFrame {
  JScrollPane jScrollPane1 = new JScrollPane();
  ATableClass tableOne = new ATableClass();
  DefaultTableModel model  = new DefaultTableModel();
 
  Boolean [] boolArray=new Boolean[] {
      new Boolean(true),
      new Boolean(false),
      new Boolean(true),
      new Boolean(false),
      new Boolean(true),
      new Boolean(false)
  };

  public TableExample1() {
    try {
      jbInit();
      tableOne.setModel(model);
      model.addColumn("CbxColumn", boolArray);
    }
    catch(Exception e) {
      e.printStackTrace();
    }
  }
  public static void main(String[] args) {
    TableExample1 tex = new TableExample1();
    tex.setBounds(10,10,300,200);
    tex.setVisible(true);
  }
  private void jbInit() throws Exception {
    this.getContentPane().add(jScrollPane1, BorderLayout.CENTER);
    jScrollPane1.getViewport().add(tableOne, null);
  }
}
