我有一组单选按钮,我想将其用作表格的过滤器。这个单选按钮在我的模型类中设置一个变量。通过我的模型中的 setter/getter ,我检索该值,并且我想使用该值作为 GlazedList 表中的过滤器。
有人知道怎么做吗?
下面是我的表格,其中 JTextField 作为过滤器:
TextFilterator<Barcode> barcodeFilterator = new TextFilterator<Barcode>() { ... };
WebTextField searchField = new WebTextField(barcodeModel.getSelectedFilter());
MatcherEditor<Barcode> textMatcherEditor = new TextComponentMatcherEditor<Barcode>(searchField, barcodeFilterator);
FilterList<Barcode> filterList = new FilterList<Barcode>(BarcodeUtil.retrieveBarcodeEventList(files), textMatcherEditor);
TableFormat<Barcode> tableFormat = new TableFormat<Barcode>() { .... };
EventTableModel<Barcode> tableModel = new EventTableModel<Barcode>(filterList, tableFormat);
barcodeTable.setModel(tableModel);
最佳答案
我会向您指出Custom MatcherEditor screencast作为实现您自己的 Matcher
来处理一组选项中的过滤的一个很好的引用。
关键部分是创建 MatcherEditor
,在本例中,它按国籍过滤人员表。
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());
}
}
}
这个 MatcherEditor
的使用方式应该不会太陌生,因为它与 TextMatcherEditor
类似:
EventList idols = new BasicEventList();
NationalityMatcherEditor nationalityMatcherEditor = new NationalityMatcherEditor();
FilterList filteredIdols = new FilterList(idols, nationalityMatcherEditor);
在上面的示例中,JComboBox
是在 MatcherEditor
本身中声明和启动的。尽管您需要对正在跟踪的对象的引用,但您不必完全遵循该样式。对我来说,如果我正在观看 Swing 控件,我倾向于使用表单的其余部分进行声明和启动,然后传递引用,例如
....
private JComboBox nationalityChooser;
public NationalityMatcherEditor(JComboBox alreadyConfiguredComboBox) {
this.nationalityChooser = alreadyConfiguredComboBox;
}
....
