Clicking on a column without disturbing the existing selection

Question

Hello good people,
I am still getting used to Swing and my question may be really silly. Thanks in advance for helping me out!
I have a JTable in which one of the columns has checkboxes. Using Ctrl+select, one can select multiple rows. Clicking without ctrl, unselects the previous selection. This is all good and default behavior. However, I would like to be able to click on one of the checkboxes in one of the selected rows and not disturb the selection. My target is to enable/disable the checkboxes of all the selected rows.
Basically, my question is: How do I not disturb the selection if a user clicks in one of the already selected rows and the checkbox column. In other words, if I clicked on the cell (r, c) where row r is already selected and column 'c' is the checkbox column, I would like to retain the selection.
Thanks,

what I meant was if you click on the flag cell of one of the selected rows, all the rows (emails) will be flaggedIn my version of Outlook (which is really old) only the row you click on will be flagged and the other rows are deselected.
But you could try adding a MouseListener to the table. When a mousePressed event is received you could save all the selected rows. You would also add a TableModelListener to the TableModel. Whenever the flag field is selected you could then loop through all the saved selected row and set the flag. You would want to remove the TableModelListener before you start the loop to prevent multiple table model events from being generated. Then when the loop finishes you would need to add the listener back to the model.
However, this is not a very good solution since it depends on the mousePressed event firing before the ListSelectionModel is updated.
