Comment faire pour rechercher deux valeurs en utilisant RowSorter JTable

Question

quand je choisis Classe et Section de ComboBox alors il devra rechercher Jtable pour la classe et la section spécifiques et montrer seulement ces classe et section?

Answer 1

Au lieu d'utiliser comboboxes plus sur la recherche, essayez d'utiliser la bibliothèque SwingBits pour votre code.

Vous pouvez trouver les fichiers jar Here.

Après cela, ajoutez cette ligne de code à votre source après avoir affiché toutes les données dans votre jtable:

TableRowFilterSupport.forTable(jTable1).searchable(true).apply(); 

Après cela, vous seriez capable de trier et filtrer les données sur l'exécution en utilisant les clics gauche et à droite votre souris respectivement.

Answer 2

C'est par exemple avec TableModel personnalisé

StudentTableModel.java

public class StudentTableModel extends AbstractTableModel implements TableModel { 
    private List<Student> data; 
    private List<Student> filtredList; 

    private Predicate<Student> predicate = student -> true; 

    public List<Student> getData() { 
     return data; 
    } 

    public void setData(List<Student> data) { 
     this.data = data; 
     filter(predicate); 
    } 

    public void filter(Predicate<Student> predicate) { 
     this.predicate = predicate; 

     filtredList = data.stream() 
       .filter(predicate) 
       .collect(Collectors.toList()); 

     fireTableDataChanged(); 
    } 

    @Override 
    public String getColumnName(int column) { 
     return "Title " + (column + 1); 
    } 

    @Override 
    public int getColumnCount() { 
     return 4; 
    } 

    @Override 
    public int getRowCount() { 
     if(filtredList == null) { 
      return 0; 
     } 

     return filtredList.size(); 
    } 

    @Override 
    public Object getValueAt(int rowIndex, int columnIndex) { 
     Student student = filtredList.get(rowIndex); 
     switch (columnIndex) { 
      case 0: return rowIndex + 1; 
      case 1: return student.getName(); 
      case 2: return student.getClassName(); 
      case 3: return student.getSectionName(); 

      default: return "N/A"; 
     } 
    } 
} 

MainFrame.java

public class MainFrame extends JFrame { 

    private JTextField textField; 
    private JComboBox<String> classComboBox, sectionComboBox; 
    private JTable table; 

    public MainFrame(String title) { 
     super(title); 
     creageGUI(); 
    } 

    private void creageGUI() { 
     List<Student> list = new ArrayList<>(); 
     list.add(new Student("Name 1", "Class B", "1")); 
     list.add(new Student("Name 2", "Class A", "1")); 
     list.add(new Student("Name 3", "Class B", "3")); 
     list.add(new Student("Name 4", "Class A", "1")); 
     list.add(new Student("Name 5", "Class A", "2")); 
     list.add(new Student("Name 6", "Class C", "1")); 
     list.add(new Student("Name 7", "Class A", "3")); 
     list.add(new Student("Name 8", "Class B", "4")); 
     list.add(new Student("Name 9", "Class A", "1")); 
     list.add(new Student("Name 10", "Class C", "2")); 
     list.add(new Student("Name 11", "Class B", "1")); 
     list.add(new Student("Name 12", "Class C", "1")); 

     setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); 
     setLayout(new BorderLayout(0, 5)); 
     setMinimumSize(new Dimension(600, 480)); 

     textField = new JTextField(20); 
     textField.getDocument().addDocumentListener(new DocumentListener() { 
      @Override 
      public void insertUpdate(DocumentEvent e) { 
       actionListener(null); 
      } 

      @Override 
      public void removeUpdate(DocumentEvent e) { 
       actionListener(null); 
      } 

      @Override 
      public void changedUpdate(DocumentEvent e) { 
       actionListener(null); 
      } 
     }); 

     JPanel searchPanel = new JPanel(new FlowLayout(FlowLayout.CENTER, 5, 0)); 
     searchPanel.add(new JLabel("Search")); 
     searchPanel.add(textField); 

     classComboBox = new JComboBox<>(new String[]{"Class A", "Class B", "Class C"}); 
     classComboBox.setSelectedIndex(-1); 
     classComboBox.addActionListener(this::actionListener); 

     sectionComboBox = new JComboBox<>(new String[] {"1", "2", "3", "4", "5"}); 
     sectionComboBox.setSelectedIndex(-1); 
     sectionComboBox.addActionListener(this::actionListener); 

     JPanel comboBoxPanel = new JPanel(new FlowLayout(FlowLayout.CENTER, 5, 0)); 
     comboBoxPanel.add(new JLabel("Class")); 
     comboBoxPanel.add(classComboBox); 
     comboBoxPanel.add(Box.createHorizontalStrut(20)); 
     comboBoxPanel.add(new JLabel("Section")); 
     comboBoxPanel.add(sectionComboBox); 

     JPanel headerPanel = new JPanel(); 
     headerPanel.setLayout(new BoxLayout(headerPanel, BoxLayout.PAGE_AXIS)); 
     headerPanel.add(searchPanel); 
     headerPanel.add(Box.createVerticalStrut(5)); 
     headerPanel.add(comboBoxPanel); 

     StudentTableModel model = new StudentTableModel(); 
     model.setData(list); 

     table = new JTable(model); 
     JScrollPane scrollPane = new JScrollPane(table); 

     JButton clearFilterButton = new JButton("Clear"); 
     clearFilterButton.addActionListener(event -> { 
      textField.setText(""); 
      classComboBox.setSelectedIndex(-1); 
      sectionComboBox.setSelectedIndex(-1); 
     }); 

     JPanel bottomPanel = new JPanel(new FlowLayout(FlowLayout.RIGHT)); 
     bottomPanel.add(clearFilterButton); 

     add(headerPanel, BorderLayout.PAGE_START); 
     add(scrollPane, BorderLayout.CENTER); 
     add(bottomPanel, BorderLayout.PAGE_END); 
    } 

    private void actionListener(ActionEvent event) { 
     StudentTableModel model = (StudentTableModel) table.getModel(); 
     model.filter(student -> { 
      String name = textField.getText(); 
      String className = (String) classComboBox.getSelectedItem(); 
      String sectionName = (String) sectionComboBox.getSelectedItem(); 

      if(!name.isEmpty() && !student.getName().contains(name)) { 
       return false; 
      } 

      if(className != null && !student.getClassName().equals(className)) { 
       return false; 
      } 

      if(sectionName != null && !student.getSectionName().equals(sectionName)) { 
       return false; 
      } 

      return true; 
     }); 
    } 
} 

et Student.java

public class Student { 
    private String name; 
    private String className; 
    private String sectionName; 

    public Student() { 
    } 

    public Student(String name, String className, String sectionName) { 
     this.name = name; 
     this.className = className; 
     this.sectionName = sectionName; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getClassName() { 
     return className; 
    } 

    public void setClassName(String className) { 
     this.className = className; 
    } 

    public String getSectionName() { 
     return sectionName; 
    } 

    public void setSectionName(String sectionName) { 
     this.sectionName = sectionName; 
    } 
}
