Add JRadioButtons in a JTable

You'd need a custom cell renderer and editor:

It would be easier to use a JCheckbox

Have a look here:

these are also worth looking at:

Thank u,
I have a last question about this,
I'm using a DefaultTableModel because I want to
dynamically add and delete rows.
But some cells may not be edited,
so I read in some tutorials that I need to use an AbstractTableModel and give it in the JTable constructor
and code the isCellEditable function.
But in the JTable constructor I'm already giving the DefaultTableModel as parameter ...

            model = new DefaultTableModel(items,columnNames());
            table = new JTable(model);

How disable some cell editing then ?
Thank you.

> You need to override isCellEditable

already been mentioned, not sure why you feel you need to repeat comments all the time.

You clearly didn't read matthew016's last question very well. I took the trouble to do so ;-)

thats strange cause u suggested exactly what I said. go figure :-D

>>u suggested exactly what I said

I actually explained what matthew016 already partially knew ;-)

>>so I read in some tutorials that I need to ... code the isCellEditable function.

Stop arguing,
no worries object I can see that u gave tip first,
CEHJ's comment was interessant as well even if I cant use this
JTable table = new JTable(new DefaultTableModel(data, columnNames) {
since I want to add rows dynamically I need the reference of the DefaultModel

>>since I want to add rows dynamically I need the reference of the DefaultModel

That's not a problem

DefaultTableModel dtm = new DefaultTableModel(data, columnNames) {
    public boolean isCellEditable(int row, int column) {
        return column != 0; // First column not editable
    }
};
JTable table = new JTable(dtm) ;

ok I did a class MyDefaultTableModel extends DefaultTableModel, it's ok as well,
Well ... then I'll just sh** up :-)
Thx.

:-)

no worries :)
