在JTable中搜索

Question

我使用Java Swing创建了一个对话窗口，它在JTable中显示一个项目列表。我想实现某种搜索功能。任何人都可以建议我实现此功能的最佳方式？

Answer 1

阅读JTable API，并按照“如何使用表格”Swing教程的链接。在那里你会找到一个关于“排序和过滤”的部分，它举例说明了如何使用文本字段来搜索包含指定文本的行。

Answer 2

这是落实JTable中搜索的方式：

 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(); 
    } 
}); 
    } 
} 

Answer 3

在SwingX看一看，和它JXTable。 SwingX提供了一组扩展普通Swing组件的组件，并为它们增加了额外的功能。我的最爱是MultiSplitPane（它是JSplitPane的替代品，可以在任意数量的可调整大小的区域中分割窗格）和JXTable，它们就像JTable一样，但也具有内置搜索功能（并且绑定到Ctrl-F）和您可以对行进行排序/过滤。漂亮的东西。您只需导入库，将JTable更改为JXTable（以同样的方式启动），然后瞧！

希望有所帮助。
