java - GlazedLists 清除在排序的 JTable 上抛出错误

Question

我想在使用 JTables 和 JXTables 的现有项目中包含 Gladedlists。主要是因为事件处理更容易。我做了一个 View 测试，在交换完整列表内容时遇到了问题。我通过调用来做到这一点

eventList.clear();
eventList.addAll(...);

仅当激活 JTable 的标准表排序时才会发生该错误。

网上有很多关于这个主题的提示，但我不明白这里的问题是什么。至少，gladedlists 不能与标准 JTable 排序一起使用吗？ 我使用的是java7，glanedLists 1.9.0，示例代码是:

package poc;

import ca.odell.glazedlists.BasicEventList;
import ca.odell.glazedlists.SortedList;
import ca.odell.glazedlists.swing.AdvancedTableModel;
import ca.odell.glazedlists.swing.GlazedListsSwing;

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;

/**
 * TestGlazedLists

 */
public class TestGlazedLists {

    public static class Person implements Comparable<Person>{
        private String name;
        private String surname;

        public Person(String name, String surname) {
            this.name = name;
            this.surname = surname;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getSurname() {
            return surname;
        }
        public void setSurname(String surname) {
            this.surname = surname;
        }

        @Override
        public int compareTo(Person o) {
            return this.getName().compareTo(o.getName());
        }
    }

    private BasicEventList eventList = new BasicEventList();
    private SortedList sortedList = new SortedList(eventList);

    private java.util.List<Person> createList() {
        ArrayList<Person> list = new ArrayList<>();
        for (int i = 0; i < 100; i++) {
            list.add(new Person("James" + i, "Bond" + i));
        }
        return list;
    }

    public TestGlazedLists() {
    }

    public static void main(String[] args) {
        new TestGlazedLists().openDialog();
    }

    private void openDialog() {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                initAll();
            }
        });
    }

    public void initAll() {
        JDialog d = new JDialog();
        d.setLayout(new BorderLayout());
        JButton refreshB = new JButton("refresh");
        d.add(refreshB, BorderLayout.NORTH);
        refreshB.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                refreshList();
            }
        });
        JTable t = new JTable();
        t.setAutoCreateRowSorter(true);

        d.add(new JScrollPane(t), BorderLayout.CENTER);

        String[] propertyNames = {"name", "surname"};
        String[] columnLabels = {"name", "surname"};
        boolean[] writable = {false, false};

        AdvancedTableModel<Person> model = GlazedListsSwing.eventTableModel(eventList, propertyNames, columnLabels, writable);
        t.setModel(model);

        //TableFormat tableFormat = GlazedLists.tableFormat(propertyNames, columnLabels, writable);
        //JXTableSupport.install(t, eventList, tableFormat, sortedList, AbstractTableComparatorChooser.MULTIPLE_COLUMN_MOUSE);

        d.setPreferredSize(new Dimension(500, 300));
        d.pack();
        d.setVisible(true);
    }

    public void refreshList() {
        eventList.clear();
        eventList.addAll(createList());
    }
}

点击第一次“刷新”有效，点击第二次崩溃

我也尝试过 JXTable 的变体，但结果是相同的。

Answer 1

让 GlazedLists 为您处理 JTable 排序。

第 1 步:删除/注释掉自动行排序器行:

t.setAutoCreateRowSorter(true); // remove me: I interfere with GlazedLists

第二步:在模型中使用排序的事件列表，而不是基本的:

AdvancedTableModel<Person> model = GlazedListsSwing.eventTableModel(sortedList, propertyNames, columnLabels, writable);

第三步:安装 GlazedLists TableComparitorChooser到您的 JTable，这会向 JTable 添加行排序功能:

TableComparatorChooser<Person> tableSorter = TableComparatorChooser.install(
        t, sortedList, TableComparatorChooser.SINGLE_COLUMN);

您现在应该会发现刷新后一切正常。单击列标题将启用列排序。如果您不喜欢 TableComparitorChooser 的多列排序方式，您可以尝试使用它的一些选项。
