How to make only some rows editable in a JTable

[sandhya raviprasad]

Hi
I have a JTable with 4 columns and 8 rows. One of the columns has checkboxes with true - false values indicating that if the value of the checkbox is true, then that row should be uneditable, if the cb value is false, then the row should be editable. Please guide me with this.

The only way that I can think of to do it is to add a Listener to the table. When any KeyEvent occurs look at the checkbox, and if it is set to true, then get rid of the keystroke.

Hi sandhya,
to make few rows editable u need to override boolean isCellEditable(int row,int column) method of JTable class.

     JTable tab = new JTable(tableModel){
     boolean isCellEditable(int row,int column)
     {
         if(row >3)
          return true;
         else
           return false;  
     }
}

actually whenever you try to edit some cell then the method isCellEditable() is fired for that row,col pair. so u can override this method to return true/false depending on whatever conditions u have.
hope that was clear.

Hi deekasha
Thanks, but I'd already solved the problem. But I guess, I picked up on the same thing as u've suggested. Thanks a lot.
I'd really appreciate it if I could get a little fast response.

Well, Sandhya, instead of complaining, how about answering your own question when you figure it out, so others don't spend their time and energy answering it.
That's what I do. After all, we don't pay to use JavaRanch!

Hi Eric
It was not a complain, but it was a suggestion. I'm sorry if you could'nt get to the sensitivity of the solution. If you did observe, I did thank Deekasha for the response which I certainly mean. Ofcourse I am aware that we don't pay JavaRanch to use it and yes, I did find the solution after a lot of struggle and research over the net and stuff. Yes, if the solution given to me did'nt help me much in time, which I'm not blaming, it may help someone else coming up with similar problems in the future.
So, please do put your words after giving it a serious thought when you're posting on such forums .. I'd really appreciate that !!!
