我有一个JTable(DefaultTableModel)和一个JTextField.我想用我放入文本字​​段的正则表达式过滤JTable.当我启动程序时,会显示所有条目,但是当我在文本字段中输入文本时,即使它应该在一行中找到文本,也不会显示任何行.

private void createFilter() {
    _sorter = new TableRowSorter<DefaultTableModel>(new DefaultTableModel());

    JPanel filterPanel = new JPanel();
    filterPanel.setLayout(new BorderLayout());

    JLabel filterLabel = new JLabel("Filter:");
    filterPanel.add(filterLabel, BorderLayout.WEST);

    _inputField = new JTextField();
    _inputField.setColumns(40);
    filterPanel.add(_inputField, BorderLayout.CENTER);
    _inputField.getDocument().addDocumentListener(new DocumentListener() {
        public void insertUpdate(DocumentEvent de) {
            newFilter();
        }

        public void removeUpdate(DocumentEvent de) {
            newFilter();
        }

        public void changedUpdate(DocumentEvent de) {
            newFilter();
        }
    });

    JButton clearButton = new JButton("X");
    clearButton.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            _inputField.setText("");
        }
    });
    filterPanel.add(clearButton, BorderLayout.EAST);

    _mainFrame.add(filterPanel, BorderLayout.SOUTH);
}

private void …

在代码审查中,出现了以下评论:"我认为,您实际上是指将工厂注入实例,以便您可以在需要时重新启动工厂." 并且"重要提示:工厂不应该是静态的,而应该注入."

Test.java:

Foo foo = FooFactory.get(argument);

FooFactory.java:

public final class FooFactory {
    public static Foo get(String argument) {
        return new Foo();
    }
}

我应该怎么做呢？"重新绑定"在评论者的第一条评论中意味着什么？

我有一个JPanel,我在其中添加了一个JScrollPane(参见下面的类).我添加了一个JTextField来验证一切正常(而不是JScrollPane)并且文本字段已添加到Panel中.当我尝试添加我的JScrollPane时,显示没有任何内容(白色背景).我该如何解决这个问题？

protected JPanel createContentPanel() {
    JPanel panel = new JPanel();
    panel.setLayout(new BorderLayout());

    final String[] columnNames = { "Test1", "Test2", "Test3" };
    final String[][] data = {
            { "foo1", "foo2", "foo3" },
            { "bar1", "bar2", "bar3" },
            { "bar1", "bar2", "bar3" },
            { "bar1", "bar2", "bar3" },
            { "bar1", "bar2", "bar3" },
            { "bar1", "bar2", "bar3" },
            { "bar1", "bar2", "bar3" },
            { "bar1", "bar2", "bar3" }
    };

    ScrollableTable scrollableTablePane = new ScrollableTable(data, columnNames);
    panel.add(scrollableTablePane, BorderLayout.CENTER);
    return panel;
}

我正在使用Bootstrap来设计我的网站.我的index.jade中有以下代码段:

form.form-inline.pull-right(action='http://localhost:1337/authenticated', method='POST')
  input.input-small(type='text', placeholder='Email', name='emailInput') 
  input.input-small(type='password', placeholder='Password', name='passwordInput')
  label.checkbox
    input(type='checkbox') Remember me
  button.btn(type='submit') Sign in

它呈现给

<form action="http://localhost:1337/authenticated" method="POST"
  class="form-inline pull-right">
  <input type="text" placeholder="Email" name="emailInput"
    class="input-small"><input type="password"
    placeholder="Password" name="passwordInput" class="input-small"><label
    class="checkbox"><input type="checkbox"></label>
  <button type="submit" class="btn">Sign in</button>
</form>

但我需要它渲染为(注意标签,而不是缩进) 编辑:实际上我需要相同的意图和"记住我"出现

<form class="form-inline pull-right" action="http://localhost:1337/authenticated" method="POST">
  <input type="text" class="input-small" placeholder="Email" name="emailInput">
  <input type="password" class="input-small" placeholder="Password" name="passwordInput">
  <label class="checkbox">
    <input type="checkbox"> Remember me
  </label>
  <button type="submit" class="btn">Sign in</button>
</form>

我该如何解决这个问题？Jade不认识"标签"元素吗？ 编辑:忘记"标签"元素,这是正确的.
