table = new CellTable<Contact>();

                        }
                };

                final CheckboxCell cCell = new CheckboxCell(false, true);
                final Column<Contact, Boolean> checkColumn = new Column<Contact,
Boolean>(cCell) {
                        @Override
                        public Boolean getValue(Contact object) {
                                // Get the value from the selection model.
                                return selectionModel.isSelected(object);
                        }
                };

                table.setSelectionModel(selectionModel);
                selectionModel.addSelectionChangeHandler(new

                        public void onSelectionChange(SelectionChangeEvent 
event) {
                                Contact selected = 
selectionModel.getSelectedObject();
                        }
                });

                table.addColumn(checkColumn);
                table.addColumn(nameColumn, "Name");

                table.setRowCount(CONTACTS.size(), true);
                table.setRowData(0, CONTACTS);

                Button btn = new Button("clear");
                btn.addClickHandler( new  ClickHandler() {
                        public void onClick(ClickEvent event) {
                                Boolean f = new Boolean(false);
                                //                              for ( int i =

                                //                                      Context
