Search in JTable

I have created with Java Swing a dialog window which presents in a JTable a list of items. I would like to implement some sort of search functions. Can anyone suggest me the best way to impl开发者_Go百科ement such feature?

Read the JTable API and follow the link to the Swing tutorial on "How to Use Tables". There you will find a section on "Sorting and Filtering" which gives an example of how to use a text field to search for rows containing the specified text.

This is a way to implement search in a JTable:

     public class JTableSearchAndHighlight extends JFrame {
     private JTextField searchField;
     private JTable table;
     private JPanel panel;
     private JScrollPane scroll;

   public JTableSearchAndHighlight() {

 initializeInventory();
  }

   private void initializeInventory() {

panel = new JPanel();

searchField = new JTextField();

panel.setLayout(null);

final String[] columnNames = {"Name", "Surname", "Age"};

final Object[][] data = {{"Jhon", "Java", "23"}, {"Stupid", "Stupido", "500"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Michael", "Winnie", "20"}, {"Winnie", "Thepoor", "23"},
                        {"Max", "Dumbass", "10"}, {"Melanie", "Martin", "500"},
                        {"Jollibe", "Mcdonalds", "15"}};

table = new JTable(data, columnNames);
table.setColumnSelectionAllowed(true);
table.setRowSelectionAllowed(true);

scroll = new JScrollPane(table);
scroll.setBounds(0, 200, 900, 150);

searchField.setBounds(10, 100, 150, 20);
searchField.addActionListener(new ActionListener() {

    public void actionPerformed(ActionEvent e) {

        String value = searchField.getText();

        for (int row = 0; row <= table.getRowCount() - 1; row++) {

            for (int col = 0; col <= table.getColumnCount() - 1; col++) {

                if (value.equals(table.getValueAt(row, col))) {

                    // this will automatically set the view of the scroll in the location of the value
                    table.scrollRectToVisible(table.getCellRect(row, 0, true));

                    // this will automatically set the focus of the searched/selected row/value
                    table.setRowSelectionInterval(row, row);

                    for (int i = 0; i <= table.getColumnCount() - 1; i++) {

                        table.getColumnModel().getColumn(i).setCellRenderer(new HighlightRenderer());
                    }
                }
            }
        }
    }
});

panel.add(searchField);
panel.add(scroll);

getContentPane().add(panel);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setTitle("Inventory Window");
setSize(900, 400);
setLocationRelativeTo(null);
setVisible(true);
  }

private class HighlightRenderer extends DefaultTableCellRenderer {

@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {

    // everything as usual
    super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);

    // added behavior
    if(row == table.getSelectedRow()) {

        // this will customize that kind of border that will be use to highlight a row
        setBorder(BorderFactory.createMatteBorder(2, 1, 2, 1, Color.BLACK));
    }

    return this;
  }
}

   public static void main(String[] args) {

SwingUtilities.invokeLater(new Runnable() {

    public void run() {

        new JTableSearchAndHighlight();
    }
});
  }
 }

Take a look at SwingX, and its JXTable. SwingX provides a set of components that extend normal Swing components and adds extra functionality to them. My favorites are MultiSplitPane (which is an alternative to JSplitPane and allows you to divide panes in any number of resizable sections) and JXTable which is just like a JTable, but also has search functionality built-in (and bound to Ctrl-F) and you can sort/filter the rows. Pretty neat stuff. All you need to do is import the library, change your JTable to JXTable (initiated the same way), and voila!

Hope that helps.
