首先，您的示例代码没有意义。它没有任何与实际 Java 代码相似的地方，也没有以任何方式遵守SSCCE原则。
也就是说，您的问题提供了足够的线索来确定您的要求。GlazedLists 确实提供了一个动态过滤列表的框架，这一切都是通过MatcherEditor类完成的。
GlazedLists Developer提供了一些很棒的截屏视频，并且有一个简单的示例准确地处理了您提出的关于如何将 MatcherEditor 与 JComboBox 选择链接起来以触发动态过滤的任务。
此示例的源代码足够短，可以在此处包含：
package ca.odell.glazedlists.example;
import ca.odell.glazedlists.*;
import ca.odell.glazedlists.gui.TableFormat;
import ca.odell.glazedlists.matchers.AbstractMatcherEditor;
import ca.odell.glazedlists.matchers.Matcher;
import ca.odell.glazedlists.swing.EventTableModel;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class CustomMatcherEditorExample {
public static class AmericanIdol {
private String name;
private int votes;
private String nationality;
public AmericanIdol(String name, int votes, String nationality) {
this.name = name;
this.votes = votes;
this.nationality = nationality;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNationality() {
return nationality;
}
public void setNationality(String nationality) {
this.nationality = nationality;
}
public int getVotes() {
return votes;
}
public void setVotes(int votes) {
this.votes = votes;
}
public void incrementVotes() {
this.votes++;
}
}
public static void main(String[] args) {
// create an EventList of AmericanIdol
final EventList idols = new BasicEventList();
idols.add(new AmericanIdol("Simon Cowell", 0, "British"));
idols.add(new AmericanIdol("Paula Abdul", 0, "American"));
idols.add(new AmericanIdol("Randy Jackson", 0, "American"));
idols.add(new AmericanIdol("Ryan Seacrest", 0, "American"));
final NationalityMatcherEditor nationalityMatcherEditor = new NationalityMatcherEditor();
final FilterList filteredIdols = new FilterList(idols, nationalityMatcherEditor);
// build a JTable
String[] propertyNames = new String[] {"name", "votes"};
String[] columnLabels = new String[] {"Name", "Votes"};
TableFormat tf = GlazedLists.tableFormat(AmericanIdol.class, propertyNames, columnLabels);
JTable t = new JTable(new EventTableModel(filteredIdols, tf));
// place the table in a JFrame
JFrame f = new JFrame();
f.setLayout(new BorderLayout());
f.add(nationalityMatcherEditor.getComponent(), BorderLayout.NORTH);
f.add(new JScrollPane(t), BorderLayout.CENTER);
// show the frame
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
private static class NationalityMatcherEditor extends AbstractMatcherEditor implements ActionListener {
private JComboBox nationalityChooser;
public NationalityMatcherEditor() {
this.nationalityChooser = new JComboBox(new Object[] {"British", "American"});
this.nationalityChooser.getModel().setSelectedItem("Filter by Nationality...");
this.nationalityChooser.addActionListener(this);
}
public Component getComponent() {
return this.nationalityChooser;
}
public void actionPerformed(ActionEvent e) {
final String nationality = (String) this.nationalityChooser.getSelectedItem();
if (nationality == null)
this.fireMatchAll();
else
this.fireChanged(new NationalityMatcher(nationality));
}
private static class NationalityMatcher implements Matcher {
private final String nationality;
public NationalityMatcher(String nationality) {
this.nationality = nationality;
}
public boolean matches(Object item) {
final AmericanIdol idol = (AmericanIdol) item;
return this.nationality.equals(idol.getNationality());
}
}
}
}
您将需要为您的特定需求构建自己的 MatcherEditor，但上面的示例提供了一个很好的模板。MatcherEditor 的目的是提供逻辑来决定过滤掉什么，或者从技术上讲，为特定输入保留什么。
您的 MatcherEditor 还需要对您希望触发过滤的组件具有某种访问权限。许多示例都将 MatcherEditor 作为特定 Swing 组件的创建者和所有者，但将其传入也同样好。
然后它只是将 MatcherEditor 连接到 FilterList 的一个例子，如果你已经完成了文本过滤，你就会熟悉它。
