Grid with checkboxes

[Strannik]

I need grid which displays checkboxes in the last column.I've found sample where TableCellRenderer and TableCellEditor interfaces are inherited.
Unfortunately this sample works if I use DefaultTableModel only. As soon as I changed model to my own checkboxes are not shown:

table = new MyTable();
table.setModel(new MyTableModel());

Are there any working samples with table model involved ?

The DefaultTableCellRenderer is a JLabel.
instead build a custom renderer:

public class YourRenderer extends JCheckBox implements TableCellRenderer {...}

implement getTableCellRendererComponent(...) and return
'this'.

If it's editable, you may wish to build a custom cell editor as well.

In your tableModel do you implement the method

public Class getColumnClass(int column)

to return a "class.Boolean" for that column ?

Thanks to all for help. I spent two days to investigate the issue and achieved something.

to hologram:

Yes, this is rather simple method to define col renderer/editor on the class level:

TR = new TextRenderer(true);
table.setDefaultRenderer(JTextArea.class, TR);

But I used another solution:

table.getColumnModel().getColumn(0).setCellRenderer(new MyBooleanRenderer());

This will allow to set custom renderer/editor for each column irrespectively of others.

But I ran across a problem and couldn't fix it. Just use another way. When I added new columns through table.getColumnModel().addColumn(column) all the columns displayed correctly.But getValueAt method of my table model was called for first column only(there was col = 0 passed only). And I had to define my own collection of columns to resolve situation.
