在2个不同的JtabbedPanes中创建相同的jtable [英] creating the same jtable in 2 different JtabbedPanes

问题描述

我想创建2个JTabbedPanes，它们在一个列中具有相同的JTable但值不同.由于某种原因，现在仅显示一个选项卡，我不确定为什么.我也是通过创建2个不同的DefaultTableModel来做到这一点的最佳方法吗?

I want to create 2 JTabbedPanes that will have the same JTable but different values in one of the columns. Right now for some reason only one of the tabs is showing up and I am not sure why. Also am I doing this the best way by creating 2 different DefaultTableModel's?

public static void tableMaker(DefaultTableModel m, DefaultTableModel m1, final Map<String, NumberHolder> uaCount)
{
    final JFrame frame = new JFrame("Strings");     
    JPanel panel1 = new JPanel();
            JPanel panel2 = new JPanel();
    JTabbedPane tabbedPane = new JTabbedPane();

    m.addColumn("String");
    m.addColumn("Occurrences");
            m1.addColumn("String");
    m1.addColumn("Occurrences");
    JTable table = new JTable(m);
            JTable table = new JTable(m1);
    table.setAutoCreateRowSorter(true);
    JScrollPane scrollPane1 = new JScrollPane(table1);
            JScrollPane scrollPane2 = new JScrollPane(table2);
    frame.getContentPane().setLayout(new BorderLayout());                                                       
    panel1.add(scrollPane1);
            panel2.add(scrollPane2);
    frame.getContentPane().add(panel1, BorderLayout.CENTER);
            frame.getContentPane().add(panel2, BorderLayout.CENTER);        
    frame.add(tabbedPane, BorderLayout.NORTH);
    tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
    tabbedPane.addTab("Tab 1", null, panel1,
                "String length 2");
    tabbedPane.addTab("Tab 1", null, panel2,
                "String length 2");

• 仅创建一个DefaultTableModel

  • create only one DefaultTableModel,

    然后所有更改都被同步，

    then all changes are synchonized,

    每个JTables可以具有不同的ColumnModel，渲染器等

    each of JTables can have different ColumnModel, Renderers, etc

    尽可能使用简单的(SSCCE)代码

    import java.awt.BorderLayout;
    import java.awt.EventQueue;
    import javax.swing.JFrame;
    import javax.swing.JScrollPane;
    import javax.swing.JTabbedPane;
    import javax.swing.JTable;
    import javax.swing.table.DefaultTableModel;
    
    public class MyTabbedPane {
    
        private JTabbedPane tabbedPane = new JTabbedPane();
        private JFrame f = new JFrame();
        private String[] columnNames = {"First Name", "Last Name", "Sport",
            "# of Years", "Vegetarian"};
        private Object[][] data = {
            {"Kathy", "Smith", "Snowboarding", new Integer(5), (false)},
            {"John", "Doe", "Rowing", new Integer(3), (true)},
            {"Sue", "Black", "Knitting", new Integer(2), (false)},
            {"Jane", "White", "Speed reading", new Integer(20), (true)},
            {"Joe", "Brown", "Pool", new Integer(10), (false)}
        };
        private DefaultTableModel model = new DefaultTableModel(data, columnNames) {
            private static final long serialVersionUID = 1L;
    
            @Override
            public Class getColumnClass(int column) {
                return getValueAt(0, column).getClass();
            }
        };
    
        public MyTabbedPane() {
            tabbedPane.addTab("Tab1", new JScrollPane(new JTable(model)));
            tabbedPane.addTab("Tab2", new JScrollPane(new JTable(model)));
            tabbedPane.addTab("Tab3", new JScrollPane(new JTable(model)));
            tabbedPane.addTab("Tab4", new JScrollPane(new JTable(model)));
            tabbedPane.setTabPlacement(JTabbedPane.TOP);
            tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
            f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            f.add(tabbedPane, BorderLayout.CENTER);
            f.pack();
            f.setVisible(true);
        }
    
        public static void main(String args[]) {
            EventQueue.invokeLater(new Runnable() {
                @Override
                public void run() {
                    MyTabbedPane frame = new MyTabbedPane();    
                }
            });
        }
    }
