Question

关于在我的Jpanel中使用JTextField，我遇到了麻烦。主文件是Jframe，里面有一个Jpanel，当我按下一个按钮时，它将Jpanel更改为另一个带有JTextField和Jtable的，JTextField是唯一一个不工作的人，我不能把文字放在里面......这就像是不可编辑的。这是我从主面板到其他面板的代码

 private void newClienteActionPerformed(java.awt.event.ActionEvent evt) {                                           
    try {
        // TODO add your handling code here:
        mainPanel.setVisible(false);
        UserJPanel users;
        users = new UserJPanel(this, mainPanel);
        visiblePanel.setVisible(false);
        visiblePanel = users;
        users.setSize(800, 600);
        getContentPane().setLayout(null);
        getContentPane().add(users);
        users.setVisible(true);
        users.repaint();

    } catch (IOException ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}

它会打开另一个jpanel，这是jTextField无法工作的那个

public class UserJPanel extends javax.swing.JPanel {

private JPanel previousPanel = null;
JFrame parent = null;
private Contactos c;
private final JPanel visiblePanel = null;
Contactos users = new Contactos();
ContactosService userService = new ContactosService();

public UserJPanel(JFrame fparent, JPanel pPanel) throws IOException {
    initComponents();
    this.parent = fparent;
    this.previousPanel = pPanel;
    limparJTable();
    preencherTabelaUsers();
}

public void limparJTable() {
    DefaultTableModel model2 = (javax.swing.table.DefaultTableModel) tabela1.getModel();
    model2.setRowCount(0);
}

public void preencherTabelaUsers() throws IOException{
    final RowPopup pop = new RowPopup(this.tabela1);
    this.tabela1.setRowHeight(this.tabela1.getRowHeight() + 10);
    DefaultTableModel tabelaFuncoes = (DefaultTableModel)this.tabela1.getModel();
    final TableRowSorter<DefaultTableModel> sorter = new TableRowSorter<>(tabelaFuncoes);
    this.tabela1.setRowSorter(sorter);
    tabelaFuncoes.setNumRows(0);
    try {
        List<Contactos> usersDados = this.userService.findAll();
        usersDados.stream().forEach(b -> {
            tabelaFuncoes.addRow(new Object[]{b.getIdcontactos(), b.getNome(), b.getApelido(), b.getCc(), b.getNif(), b.getTelefone(),b.getEmail()});
        }
        );
    }
    catch (Exception erro) {
        JOptionPane.showMessageDialog(null, erro);
    }
}

用红色矩形检查图像，我可以插入任何文本

任何帮助？

更新

唯一不工作的部分是jTextField，Jtable工作正常，检查图像

检查jTextField，我已经删除了toolTipText，现在是空的，但是当程序运行时它是不可能的... 关于布局，当我将元素放入Jpane

时，会自动生成initcomponents（）方法

那有什么不对？

Java JTextField无法在Jpanel中输入文本
