[英]How to access DefaultTableModel from another class
I intend to have a form (FLlistes) that shows a table populated with data from taken from a database with hibernate.我打算有一个表格(FLlistes),它显示一个表格,其中填充了从休眠数据库中获取的数据。 The problem is that I don't know how to access the table (or table model) from the class I use to create the queries.问题是我不知道如何从我用来创建查询的类访问表(或表模型)。
I created a jtable in a JInternal frame like this:我在 JInternal 框架中创建了一个 jtable,如下所示:
public class FLlistes extends JInternalFrame {
private JTable table;
private DefaultTableModel model;
//some code
String[] columns = {"Id","Date", "Place", "Total"};
model = new DefaultTableModel(columns, 0);
table = new JTable(model);
JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(49, 176, 732, 361);
getContentPane().add(scrollPane);
scrollPane.setViewportView(model);
//some code
}
I have another class that makes the queries to populate the table with Hibernate:我有另一个类,它使查询以使用 Hibernate 填充表:
public class AccionsBD {
public static void GetALLLlistes() {
String jql = "select llc from LlistaCompra llc";
EntityManager entityManager = JPAUtil.getEntityManagerFactory().createEntityManager();
TypedQuery<LlistaCompra> q = entityManager.createQuery(jql,LlistaCompra.class);
List<LlistaCompra> llistes = q.getResultList();
for (LlistaCompra llista: llistes) {
String[] row = {Integer.toString(llista.getIdLlista()), llista.getData().toString(), llista.getLloc()};
model.addRow(row);
}
entityManager.close();
}
}
The problem is that i don't know how to access model in model.addRow(row);
问题是我不知道如何在model.addRow(row);
访问模型model.addRow(row);
in order to fill the table为了填表
Make FLlistes
as singletone and provide a getter method for DefaultTableModel
property.将FLlistes
设为FLlistes
并为DefaultTableModel
属性提供 getter 方法。 Then you can access getModel()
from singletone object .然后你可以从单调对象访问getModel()
。
public class FLlistes extends JInternalFrame {
private JTable table;
private DefaultTableModel model;
public DefaultTableModel getModel(){
return model;
}
//Singletone implemenation
}
