RowFilter for JTable

Question

I am trying to implement a RowFilter for my JTable but the issue is that my Table fetches data from a database and my table uses a JTextArea custom renderer for one column, I have implemented the RowFilter and it does work.

The problem is that when I search for data the table defaults back to normal view like how you would see it without the renderer, I want that when searching is done the table should retain its aesthetics. Please help. here is my code:

this is my renderer:

class wrap extends JTextArea implements TableCellRenderer {
        wrap() {
            super();
            setLineWrap(true);
            setEditable(false);
            setWrapStyleWord(true);
            setBorder(BorderFactory.createEmptyBorder(5, 10, 5, 10));
        }

        @Override
        public Component getTableCellRendererComponent(JTable jtable, Object value, boolean bln, boolean bln1, int i, int i1) {
            setText((String) value);
            setForeground(Tab.getForeground());
            setBackground(Tab.getBackground());
            setFont(Tab.getFont());
            return this;
        }

This is how i set my table:

public void ViewReports() {
        load l5 = new load();
        l5.setVisible(true);
        l5.j1.setText("Fetching Report.");
        SwingWorker worker1 = new SwingWorker() {
            @Override
            protected Void doInBackground() throws Exception {

                if (con == null) {
                    try {
           Class.forName("com.mysql.jdbc.Driver");
           con = DriverManager.getConnection("Connection Details go here");

                    } catch (Exception ex) {
                 JOptionPane.showMessageDialog(tcom, "Connection error.");
                    }
                }
       try {
 PreparedStatement ps = con.prepareStatement("select S_id as 'ID',c_name as 'Candidate Name',C_num as 'Number',Comments,call_status as 'Call Status', date_format(date1,'%d-%b-%y') as 'Date' from CallRecords order by S_id desc;");
                     rs5 = ps.executeQuery();
                } catch (Exception e) {
                }
                return null;
            }

            @Override
            protected void done() {
             Tab.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
             Tab.setModel(DbUtils.resultSetToTableModel(rs5));
             Tab.getColumnModel().getColumn(3).setCellRenderer(new wrap());
                    updateRowHeights(3, 300);

                    TableColumn c1 = Tab.getColumnModel().getColumn(0);
                    TableColumn c2 = Tab.getColumnModel().getColumn(1);
                    TableColumn c3 = Tab.getColumnModel().getColumn(2);
                    TableColumn c4 = Tab.getColumnModel().getColumn(3);
                    TableColumn c5 = Tab.getColumnModel().getColumn(4);
                    TableColumn c6 = Tab.getColumnModel().getColumn(5);

                    c1.setPreferredWidth(50);
                    c2.setPreferredWidth(130);
                    c3.setPreferredWidth(120);
                    c4.setPreferredWidth(350);
                    c5.setPreferredWidth(100);
                    c6.setPreferredWidth(100);
                try {
                    rs5.close();
                } catch (SQLException ex) {}
                l5.dispose();
            }
        };
        worker1.execute();
}

and here is my Filter Method:

 private void filter(String filterText){
            TableModel dm =(TableModel) Tab.getModel();
            TableRowSorter<TableModel> tr=new TableRowSorter<>(dm);
            Tab.setRowSorter(tr);
            tr.setRowFilter(RowFilter.regexFilter(filterText));
        }

 private void RecordFilterKeyReleased(java.awt.event.KeyEvent evt) {                                         
         String Text = RecordFilter.getText();
         filter(Text);
    }  

I have also used DefaultTableModel instead of TableModel but to no avail. Any suggest will be highly appreciated.

Answer 1

Tab.setModel(DbUtils.resultSetToTableModel(rs5));

First of all variable names should NOT start with an upper case character. Some of your names are correct, others are not. Be consistent and follow Java conventions!

Whenever you reset the model on a JTable the custom renderers and editors are reset.

So you need to add the custom renderer to the table AFTER setting the model.
