I set the checkbox to the jtable using default model, by using following code:

  Object[] ColumnData = {"Sr No","Ward Name","Total voters","Action"};
  Object[][] RawData=null;

//loop

model.insertRow(x, new Object[]{ key,ward_name_var,total_vot_var,new Object[]{o}});
model.setValueAt(o,x,3);
tblWard.setModel(model);

Setchk(tblWard,3,checkbox);// by calling this method which refers renderer

//set renderer each time when i fill the rows by using database

 private void Setchk(JTable jTable1, int i, JCheckBox checkbox) 
  {
    jTable1.getColumnModel().getColumn(i).setCellRenderer((new CWCheckBoxRenderer()));
    jTable1.getColumnModel().getColumn(i).setCellEditor(new CheckBoxCellEditor());
  }

But my database having large number of records, when I click on any checkbox it runs to check state of each and every checkbox contain in same column.

It can decrease performance of mine system so provide me solution for how I avoid situation so it will not go to check the state of all checkboxes.

Please suggest a book or link to understand the Renderer property of jtable.

  • welcome to the forum :-) For starters, be sure you read and understood the table related chapter in the tutorial referenced in the swing tag description. If you are still stuck, show a SSCCE (google is your friend :-) which demonstrates the exact problem you'r facing – kleopatra Mar 28 '12 at 11:22

    I think an edit of your [previous question](http://stackoverflow.com/questions/9905362/how-to-set-renderer-to-checkbox-on-jtable-for-row) was more appropriate then just starting a new one, so I voted to close this question – Robin Mar 28 '12 at 18:41
