Question

I am using Java beans binding to bind Jtable and in which api gives the default values for integer or float values such as 0 or 0.0 as shown below.I would like to avoid the corresponding default values and set the cells as empty except last cell value.

1        WW     88.0        88.0      1021021       340.0       
4        TT     55.0        55.0      1021021       340.0       
5        PP     66.0        66.0      1021021       340.0

                0            0          0           1020

2        gg     66.0        66.0      1021022       320.0       
3        LL     658.0       652.0     1021022       320.0

               0            0          0             640

and the table should looks like ..

1        WW     88.0        88.0      1021021       340.0       
4        TT     55.0        55.0      1021021       340.0       
5        PP     66.0        66.0      1021021       340.0

                                                    1020

2        gg     66.0        66.0      1021022       320.0       
3        LL     658.0       652.0     1021022       320.0

                                                     640

any one who can suggest the better way to solve this problem, it will be great full and thanks in advance.

Answer 1

I was using Jtable beans binding and using beansbinding-1.2.1.jar api for auto binding. I downloaded the beansbinding-1.2.1.jar source and make relevant changes in the class

/org.jdesktop.swingbinding.JTableBinding.java

containing the class BindingTableModel.java which implements the TableModel and I overridden the method as per the suggestions of above two friends and thanks to all...

@Override

public Object getValueAt(int row, int column) {
            Object value = valueAt(row, column);

            if (value != null
                    && (value.toString().equals("0") || value.toString()
                            .equals("0.0")|| value.toString().equals("default"))) {
                return null;
            }

            return value;
        }
