Custom JTable column (JCheckBox) not included in row selection.

Question

I am trying to use JCheckBox (for display only data) as one of my JTable columns. I have written custom cell renderer for the same. Every thing is working fine except that when I select a row, the new custom JCheckBox column is not included in selection. Here is the code that I am using.
    protected class CheckBoxColumnRenderer extends DefaultTableCellRenderer {
        JCheckBox ckb = new JCheckBox();
        public Component getTableCellRendererComponent(JTable table, Object value,
                    boolean isSelected, boolean hasFocus, int row, int column) {
            if (value instanceof Boolean) { // Boolean
              ckb.setSelected(((Boolean) value));
              ckb.setHorizontalAlignment(JLabel.CENTER);
              ckb.setBackground(super.getBackground());
              if (isSelected || hasFocus) {
                  ckb.setBackground(table.getSelectionBackground());
            return ckb;
    }How can I include the custom cell in the row selection.
regards,

Answer 1

they have lots of dependencies and it is not always easy to strip out an SSCCE without a considerable effort.Exactly. And is the cause of the problem the dependencies or something else. The only way to know for sure is to strip out the code and simplify the problem, that way you truly understand what the problem is.
The majority of time this can be done with minimal effort as in this case.
Some times we are sure that the problem is with certain part of the code Is the problem the code or the way the code is invoked? How do we know the TableModel is created properly or that the column class is overwritten correctly when we can't see it?
someone having a third look at it may actually find the enhancement required with ease.Exactly, but we need to see the big picture.
So are you sure that I should post an SSCCE with every possible question where coding is involved ?In the majority of cases a SSCCE is easily created in 5-10 minutes, so if you want the fastest help then yes.
Just twice this past week I was ready to ask a question on the forum and was preparing a SSCCE to post and sure enough both times the creation of the SSCCE caused me to look at the problem differently and I solved it. I would much rather solve a problem on my own then post a question and wait for hours (days) hoping someone else knows the answer.
